BECM locked out or in alarm? Have another BECM that requires programming for your vehicle? Do you want some functions enabled or disabled? Program a new remote(s)?
Much of the information in a BECM can be changed using standard diagnostic software. Changing or accessing either the EKA code or the FOB code for the remotes requires unlocking the BECM, which is a bit more difficult to do as it requires specialist software and disassembly of the BECM to directly connect to the CPU chip on the logic board inside.
When your BECM is in alarm and you are locked out try to input the EKA code. If you do not have the EKA code contact your Land Rover dealer and ask them to retrieve it from the security records for your vehicle held by Land Rover. The 95 model year did not have this feature activated but, so far, all the ones that I have activated have worked. NOTE: A driver's door latch failure is quite likely to prevent EKA input and may cause the BECM to go into alarm and lockout.
If you cannot get the BECM out of alarm and lockout then you will have to remove it from the RR and send either the entire BECM or the Logic Board from the inside. Sending the entire BECM in Australia is not too difficult or expensive, however, doing this from outside of Australia will be expensive. This is why I have included instructions of removing the much smaller and lighter Logic Board.
Data in a BECM that I usually program
BECM current alarmed status: This enables the BECM to be reset to the not alarmed status. Unknown will be displayed if the value stored in the BECM is not a valid value. You cannot set the status to unknown.
Current EKA lockout status: This enables the BECM to be reset to to normal status. Unknown will be displayed if the value stored in the BECM is not a valid value. You cannot set the status to unknown.
EKA number: This is the Emergency Key Access (EKA) Number for this vehicle. Only available on unlocked BECM's (see BECM STATUS). Even if the EKA function is disabled (see PASSIVE EKA) and therefore not used, each BECM still has a number programmed into it. The number has to be 4 characters long, each character can be a number between 1 and 6, and the four numbers cannot be all the same.
Engine: Select between the later Motronic Petrol engine management that is fitted after 1999 and can be distinguished by the overlapping sausage effect of the intake plenum on the top of the engine. GEMS petrol engine management fitted before 1999, which can be distinguished by the flat-topped intake plenum with the engine capacity shown on the top of the engine or the Diesel EDC engine management.
EMS code: Only used on GEMS and Motronic engine Management Systems (EMS). When the ignition is turned on, the BECM, providing it is in receipt of a valid mobilization code, from receiving an unlock signal from the correct key fob or having its EKA code entered, and is therefore not in an alarmed or immobilised state, sends a coded signal to the Engine Management System (EMS) ECU and in turn, the EMS ECU then compares against a code it already has stored in it. If the two codes compare OK, the EMS ECU allows the engine to start. This forms the basis of the immobiliser. If the EMS ECU or the BECM is replaced, the two codes will not match and it will not be possible to start the engine. It is therefore necessary to synchronise the codes in both the BECM and the EMS ECU. For GEMS, a function can be found in the GEMS section that gives the fixed code from the GEMS ECU that must be entered here. For Motronic, any number can be used here as the Motronic ECU has a learn function located in the OTHER section which can be used to force it to learn this code.
BECM Status: The BECM has an electronic lock that is designed to prevent access to some of its contents. All BECM's are locked in this way at the vehicle factory after they are programmed with the information specific to the vehicle they have been fitted in. However, replacement BECM's are supplied unlocked and all data can be readily accessed and changed up until the point when the unit is locked. This is currently an irreversible process so it is important to check the correctness of all information stored in the BECM before considering locking it. The lock status has no effect on any other operation of the BECM. RovaCom software has the ability to unlock a BECM using the SM035 software.
It is acceptable to leave the status of the BECM unlocked for normal vehicle usage, which is what I do after accessing the CPU.
FOB code: For security this information is only available to be read or programmed on unlocked BECM's (see BECM STATUS). The fob code is a 3-part code, which uniquely identifies the family of key fobs (key 1, key 2, etc.) that go with this vehicle. Any key Fob, when pressed, transmits its unique electronic ID code (FOB CODE) in an encrypted format. The BECM of any vehicle within range of that key fob decrypts the received transmission and compares the FOB CODE that was received, against the FOB CODE that is stored. If the two match, it will accept the key as valid and perform the relevant task (lock, unlock, send mobilize signal to engine ECU, etc). This FOB CODE is derived from converting the manufacturer's lockset bar code. This is a 14 digit alphanumeric number, which is printed on a label that accompanies every new key fob or lockset. When the vehicle was assembled at the factory and was first fitted with its new lock set, the lockset bar code was recorded along with the vehicles VIN number. This can be obtained from Land Rover records by asking your local dealership and quoting the Vehicle's VIN number. If the lockset bar code given by the dealer is no longer correct for the vehicle (due to an earlier replacement of the lockset and where the kept records were not updated), there is then no alternative but to replace the lockset and use the new lockset bar code that comes with it. When you have the lockset bar code, do not attempt to enter this directly, but e-mail this to me and I will forward it to the BlackBox Solutions help desk who will convert the lockset bar code into a the 3-part FOB CODE. This FOB CODE is then entered into the BECM. The FOB CODE can only be obtained by this method. If you have a remote and do not have either the lockset barcode or the FOB code it is a paperweight. Refer to the section on remotes for more information.
I can also turn off the Alarm and passive immobilisation, change engine and transmission types etc,
General Functions and settings in a BECM that can be changed
- Alarm: The alarm can be either enabled or disabled if required. Disabling the alarm prevents the alarm from arming and stops all audible and visual activity whenever the vehicle is locked or unlocked. It does not affect the immobilization.
- Alarm lights: This changes the method of visual output from the BECM used for the alarm activated / triggered.
- Arm/disarm: Changes the method of visual notification of alarm arming and disarming.
- Daylight running: Either headlamps or sidelights can be selected as the daytime running lights or the function can be disabled.
- EKA: To enable or disable the Emergency Key Access (EKA) code input from the driver’s door lock.
- Immobiliser: Turns on/off the passive (self) immobilise function in markets that use it. Only passive, not active, which cannot be deactivated.
- Key warning: When enabled, the warning gong will sound continuously whilst the keys are in the ignition and the ignition is turned off.
- Mislock: Changes the method of notification of error on alarm arming between using the interior light or the alarm sounder.
- Sunroof: This denotes whether an electric sunroof is fitted to the vehicle or not.
- Trip computer: This denotes whether a trip computer is installed in the vehicle or not.
- Window cancel: Some markets allow operation of the windows and sunroof for a period of time after the ignition is turned off and the door is opened; some have immediate cancellation of operation when the ignition is turned off and others have no cancellation at all.
- Wiper speed: Enables the windscreen wipers to go to intermittent when the RR has stopped and returned to wipe when moving off.
- Range lamp: This is used to enable or disable the high or low range selector back lamp function.
- Gearbox: This denotes whether the gearbox is manual or automatic.
- One touch: This specifies which windows have the 1 touch functionality.
- Lazy locking: Changes the situation in which lazy locking is allowed.

BECM Remove and Refit
Instructions for removing the BECM
Please insure that you have the radio code before starting.
Step 1 – Go to the engine bay fuse box and remove the three large 60 amp (blue) fuses. Remove the rear one first, the middle one and the front one last. These fuses supply power to the three brown wires on the outside of the BECM.
Step 2 - Locate BECM - it is large black box with a finned aluminium lid located under driver's seat and remove the plastic seat trims from around the seat base.
Step 3 - Using a T50 Torx bit and suitable driver, loosen the rear two seat mounting bolts. Remove the front two seat mounting bolts and tip the seat backwards just far enough to unplug the cables from under the seat bottom. Lower the seat and remove the two rear seat mounting bolts. Prepare the rear seat to receive the front seat by clearing it off, insure the seat backs are up and place a piece of sturdy cardboard or carpet upon the seat base. Caution the front seat is heavy. Lift the seat up, back and tip sideways to place it on its left hand side onto the rear seat with the headrest furthest away from you. NOTE: You do not have to unbolt the seatbelt from the seat.
Step 4 - Unscrew the plastic duct on top of the BECM and remove it.
Step 5 - Undo the three 10mm power terminal connection nuts (brown wires) on the outer face of the BECM (next to the fuses). Note their order so that they are put back in their correct order later.
Step 6 - Undo the 10mm earth terminal connection nut (black wire) to the left of the 3 that were just removed in step 5.
Step 7 - Undo the three 10mm nuts that hold the BECM to the floor of the vehicle.
Step 8 - Disconnect all multi plugs from the BECM and remove the BECM from the vehicle.
Reverse the above procedure to refit the BECM to the vehicle.
Follow the EKA and Power Up procedure and then recode the radio.
You are away!
NOTE: While the BECM is removed – locate the earth stud on the floor, under the carpet behind the seat – follow the black earth wire. Remove the nut and ring terminals and thoroughly clean the lot - especially remove any grey paint on the stud face. Refit and tighten.
EKA, BECM Power Down and Power Up
Emergency Key Access (EKA) for the LP (P38) Range Rover
If the vehicle is locked using the remote handset and loss or failure of the handset occurs, the vehicle can be unlocked and the alarm disarmed by entering a four-digit code using the key in the driver’s door lock. The code is a unique code for the vehicle and can be found on the security information card or it is obtainable from Land Rover.
EKA procedure - Vehicles up to 96MY
1. Unlock driver’s door with the key.
2. Open the door and the alarm sounder will sound twice. If the key is inserted in the ignition at this point and an attempt is made to start the engine, the engine will not crank and the message centre will display ’ENGINE DISABLED PRESS REMOTE OR USE KEY CODE’.
3. Close the driver’s door and ensure that: All doors, tail door and bonnet must be closed. This is a must do, otherwise the EKA will not work.
4. Turn the key to the lock position.
NOTE: The code cannot be entered if the message centre displays ’KEY CODE LOCKOUT’. (see below)
5. Enter the code as follows. At each turn of the key to the lock or unlock position, the side lamps warning lamp in the instrument pack will flash to indicate that the key turn has been recognized.
6. Enter the first digit. If the first digit is 2, turn and release the key two times in the unlock direction.
7. Enter the second digit. If the second digit is five, turn and release the key five times in the lock direction.
8. Enter the third digit. If the third digit is four, turn and release the key four times in the unlock direction.
9. Enter the fourth digit. If the fourth digit is two, turn and release the key two times in the lock direction.
10. Turn the key to the unlock direction and, provided that the code has been entered correctly, all the doors and the tail door will be unlocked and the alarm will be partially disarmed.
When the EKA code has been entered, the security LED will continue to flash in deterrent mode to show that the alarm is partially disarmed and will be triggered if the bonnet is opened.
If the EKA code is entered incorrectly, on the final unlock turn of the key, a mislock will sound and the remaining doors and the tail door will remain locked and the alarm partially armed. If five incorrect attempts are made to enter the code, the BeCM enters a ten-minute ’lockout’ period. Further attempts to enter the code will cause a mislock to sound each time the key is turned. During the lockout period, the message centre displays ’KEY CODE LOCKOUT’.
If you make a mistake while entering the code open either of the front doors, a mislock will sound and the door will need to be closed and key locked and the code re-entered from the beginning. This will not count as an incorrect EKA entry.
With the vehicle in EKA mode, if the remote handset unlock button is pressed all doors will be unlocked and the alarm disarmed. The lock button will not operate while entering the EKA code.
EKA procedure - Vehicles from 96MY
If the vehicle is locked using the remote handset and loss or failure of the handset occurs, the vehicle can be unlocked and the alarm disarmed by entering a four digit code using the key in the driver’s door lock as described in the EKA procedure for vehicles up to 96MY with the following exceptions:
1. If the vehicle had not been locked with the remote handset, then in step 4, the key must be turned four times to the lock position.
2. The number of incorrect attempts is reduced to three and the lockout period increased to thirty minutes.
Powering up a P38 BECM
I have found that this procedure has worked for me almost all of the time.
NOTE: This may not work if the message centre displays ’KEY CODE LOCKOUT’. (See above)
When you are locked out, have had a flat battery, battery replacement or are removing and refitting the BECM:
1 - Go to the engine bay fuse box and remove the three large 60 amp (blue) fuses.
Remove the rear one first, the middle one and the front one last.
These fuses supply power to the three brown wires on the outside of the BECM.
If you are removing and refitting the BECM leave the battery terminals connected to keep power
going to the other computers. With the three fuses removed there is no power at the BECM.
2 – With a charged battery fitted (and the BECM refitted and connected).
3 – Open the driver’s door and leave it open.
4 – Fit only one key/remote into the steering column lock do not turn it! If more than one key/remote is near the ignition lock there will be multiple signals transmitted and the BECM will not be able to do a friendly mobilization.
5 – Replace the three fuses in the reverse order, front one first, middle and rear last.
As the BECM powers up (with the key fitted in the steering column and the driver’s door open) it should do a friendly mobilization sequence.
If it does not then remove the fuses in the above order, turn the ignition key to the ignition on position and refit the fuses in the above order. (Some girls do it one way, some the other!)
If the other doors unlock at this time then close and open the driver’s door or any other door. If a door is not opened within one minute the vehicle will automatically relock all the doors and arm the alarm.
You will now have to re-synchronise the remote(s) to the BECM.
Put the remote key into the driver’s door lock and turn it to the lock or unlock position and quickly return it to the rest position. Quickly push either button on the remote once. Repeat the above several times until the remote re-synchronises with the BECM. You will know when this happens, as all the doors will start to lock and unlock with the pushing of the remote buttons.
Unlock the vehicle and open the driver’s door (or any door). If a door is not opened then, within one minute, the vehicle will automatically relock all the doors and arm the alarm.
Insert the key into the ignition lock and when the key is turned the engine should start.
Recode the radio then reset the windows and sunroof.
Windows - one at a time, drive each window to the fully open position, short pause, drive the window to the fully closed position (in one continuous movement), pause at the top until notified the window is set.
Sunroof – do each operation in one continuous movement fully open the sunroof, pause, fully close the sunroof, pause, fully open to tilt position, pause, fully close, pause until notified the sunroof is set. Each of the motor drives has an encoder that sends a stream of pulses while the motor is running, the BECM counts the pulses and puts them in memory so that it knows when the window or sunroof is in the closed position.
Interruption or non reception of the pulse stream at the BECM means there will be no reset notification.
Any feedback appreciated.
Front door functions not working
P-38 Range Rover - Front door - central locking, window, mirrors not working
Check fuse 9 and 22 on the BECM – there should be a Fuse warning in the instrument cluster
When a faulty outstation is suspected the left and right can be swapped, as they are identical.
It is known that a problem exists where the harnesses run in the sill channels (especially the red wires). Moisture in the sill channel can eventually permeate the insulation and the copper wires inside will corrode. This will give a very high ohms reading or even open circuit on the affected wire(s). When the loom in the sill channel has been un-taped a corroded wire will visually look OK but will exhibit elasticity when pulled from the ends. Cut out the entire section of any affected wires in the sill channel and replace it using soldered and insulated connections at both ends. Retest for continuity with a multimeter while moving and stretching the repaired wire(s).
With both ends disconnected there must be good continuity (very low ohms) when each wire is tested using a multimeter by back-probing the terminals. Move the loom in the sill while measuring the resistance. There must be no resistance between a wire and earth when tested except for the black earth wires, which should have very good continuity to earth.
From each door outstation there are 8 wires in C755R and C755L the black 16 pin connectors
The purple wire with the blue trace, terminal 6, is battery power from Fuse 22
The purple wire with the black trace, terminal 10, is battery power from Fuse 9
There are two black earth wires, terminals 7 and 9
The purple wire with the orange trace, terminal 3, carries mirror position data
The orange wire with the green trace, terminal 15, carries the serial data direction signals
The light green wire, terminal 13, carries the serial data
The red wire, terminal 14, carries the clock (or timing) signals
BECM to the right front door outstation:
C326 (C1285) is the blue 20 pin connector on the bottom row at the front of the BECM.
C323 (C1284) is the grey 12 pin connector on the top row at the front of the BECM. It has the two power wires in terminals 2 and 12.
E328 is the earth point located on the side of the wheel arch under the seat latch mechanism on the right hand side of the luggage space.
BECM to the left front door outstation:
C362 (C1286) is the black 16 pin connector on the bottom row at the front of the BECM. Terminals are 1, 8, 9 and 10. The harness goes behind the centre console and behind the left seat then into the left side sill channel up to a 12 way black connector located at the A pillar end of the flex tube going to the door and then up through the tube and door to the outstation. C361 (C1291) is the white 18 pin connector on the inside at the front of the BECM. It has the two power wires in terminals 6 and 10.
NOTE: under the left seat wires have been found to be short circuit to the seat base mountings E367 is the earth point located on the side of the wheel arch under the seat latch mechanism on the left hand side of the luggage space.
In the Land Rover circuit diagrams Cxxx are connector numbers for Range Rovers up to and including 1999, the numbers in brackets (Cxxxx) are for 2000 onwards.
Intermittent non-start due to engine immobilization
We are having much ado about the electrical integrity of the gold plated terminals used in connecting the BECM to the ECM. These terminals, which are used for signals, handle only very low power levels and therefore are susceptible to corrosion occurring between the gold plating and the base metal of the body of the terminal’s. Disturbing them by disconnection and reconnection may temporarily cure the problem as the physical act seems to displace the insulating corrosion however the only permanent solution that we have found is to put a very, very small amount of contact treatment solution on the gold terminals. We have been doing this for years on these gold terminals (and the connectors under the seats for seatbelt pretensioners - among others) and have not had any further problems.
Use only contact treatment solutions that are made for gold contacts.
Try the electronics stores in your area for the contact treatment solution that is used on the gold connectors for audio/visual equipment. Jaycar has stores throughout Australia and New Zealand. They have Deoxit - contact cleaner and rejuvenator – NS-1434 Aerosol can or NS-1436 Solution Kit.
Terminals to treat
BOSCH Motronic ECM: Pin 5 of the 16-pin green connector on the front of the BECM has a black wire sending the coded bit stream to pin 33 of the ECM through pin 1 of the body/engine harness connector. Pin 20 on the ECM has a white wire with a blue trace that sends the MIL signal back to pin 5 of the 20-pin green connector on the front of the BECM through pin 15 of the body/engine harness connector. The BOSCH Motronic ECM connector is the 40-pin second from the end.
GEMS ECM: Pin 5 of the 16-pin green connector on the front of the BECM has a black wire sending the coded bit stream to pin 26 of the 36-pin red connector of the ECM through pin 1 of the body/engine harness connector. Pin 22 of the 36-pin black connector on the ECM has a black wire with a yellow trace that sends the MIL signal back to pin 5 of the 20-pin green connector on the front of the BECM through pin 4 of the body/engine harness connector.
The body/engine harness connector is located under the coolant expansion tank in the engine bay.
If you are not getting the check engine light (MIL) in the instrument cluster either the EMS code is not getting to the EMS unit through the black wire or the EMS is not returning the MIL signal back to the BECM on the black wire with the yellow trace (GEMS) or white wire with a blue trace (BOSCH). The check engine (MIL) light must be on for the BECM to crank the engine with GEMS. With BOSCH the engine will crank but there will not be any injection or spark.
Remove and refit the connectors on the EMS a couple of times and then, if that has not fixed it, unclip the coolant expansion tank and move it aside, then pull apart and put back together the connector(s) under it a couple of times. You must have a check engine light on (unless the globe is blown)
When the ignition switch is turned to position 3 (crank) the relays you can hear clicking in the BECM have nothing to do with cranking the engine. The relays are performing other functions (mostly power saving). When the key is turned to position 3 there is an IC in the BECM that silently switches the starter relay in the engine bay fusebox and is only enabled when there is a MIL signal (GEMS), not in alarm or immobilized and the gearbox is in park/neutral.
It is not uncommon for the gear selector switch to fail on these transmissions as the drain for the A/C is almost on top of it and drips condensate on it. Is the gear indication displayed correctly in the instrument cluster?
GEMS - You can try to bypass the starter relay as you may also have a faulty relay, blown crank fuse (shared with the EAS) or the starter motor has packed it in. On the front of the BECM on the top row at the transmission tunnel there is a 10 pin yellow connector. Terminal 2 has a white wire with a red trace and earthing this wire will energise the crank relay (SM) in the fusebox if the 30 amp MAXI 2 fuse is not blown. If the solenoid and starter motor are OK the engine will crank. If the ignition is switched on it will fire up.
Caution this disables the Park/Neutral inhibit and if the gearbox is in a gear the Range Rover will take off.
If you bare both ends of a small diameter wire (of suitable length) and stick one end into the back of the number 2 terminal on the 10 pin yellow connector (careful to get all the strands inside and not short circuiting to another terminal) and earth the other end the engine will crank if all the above are OK.
If the non-start problem persists, please go the GEMS Mobi4 section.
Logic Board Remove and Refit
Instructions for removing the Logic Board from inside of a BECM
Step 1 – Move the BECM to a cleared workbench and use a T8 Torx bit to remove all 8 of the course threaded screws around the outside edge of the aluminium lid. Put the screws in a separate labelled small plastic bag.
Step 2 - Using a T8 OR T10 Torx bit remove all 11 of the machine thread screws in the middle of the aluminium lid and remove the lid. Put the screws in a separate labelled small plastic bag.
Use a static safe work mat, wrist strap and follow static safe work principals.
Step 3 - Locate the 4 grey ribbon cables with red header connectors coming up around three edges of the upper PCB (power board).
Step 4 - Carefully unplug each of the 4 connections by pulling straight up on the red header connectors. Be careful to pull up evenly on the red connector ends only to avoid bending any pins as they separate.
Step 5 - Bend the ribbon cables backwards so that the disconnected header connectors are hanging outside of the BECM 's outer case.
Step 6 - Lift the power board up and hinge it back on its wires about 140 degrees, to the side with the Fuse box until it is out of the way of the screws holding the logic board in the bottom of the case.
Step 7 - Using a T8 Torx bit unscrew the 7 course threaded screws which hold the logic PCB in the bottom of the BECM box and remove the lower PCB (Logic Board). Put the screws in a separate labelled small plastic bag.
Step 8 – Place the Logic Board in a static safe bag and securely pack for transport to me for programming..
NOTE: You should be able to source a suitable static safe bag from a computer repair store. (PC motherboard anti static bag) Hopefully you may also be able to get a box and other protective packaging.ss
Refitting the logic circuit board is the reverse of the above.
Remotes: Only multiple remotes with the same lockset barcode and FOB code can be programmed to a BECM.
Remotes come in four classes, 1, 2, 3, 4 only 1 and 2 will operate the seat and mirror memory (if fitted and working).
If you have a remote that will not synchronise to your RR and do not have either the lockset barcode or the FOB code it is a paperweight.
FOB code - The FOB code is a 3-part code, which uniquely identifies the family of key fobs (remotes) (key 1, key 2, etc.) that go with a vehicle. Any key fob, when pressed, transmits its unique electronic ID code (FOB CODE) in an encrypted format. The BECM of any vehicle within range of that key fob decrypts the received transmission and compares the FOB CODE that was received, against the FOB CODE that is stored. If the two match, it will accept the key as valid and perform the relevant task (lock, unlock, send mobilize signal to engine ECU, etc). For security, this information is only available to be read or programmed on unlocked BECM's (see BECM STATUS in the BECM programming section).
The FOB CODE is derived from converting the manufacturer's lockset bar code. This is a 14 digit alphanumeric number, which is printed on a label that accompanies every new key fob or lockset. When the vehicle was assembled at the factory and was first fitted with its new lockset, the lockset bar code was recorded along with the vehicles VIN number. This can be obtained from Land Rover records by asking your local dealership and quoting the Vehicle's VIN number. If the lockset bar code given to you by the dealer is no longer correct for the vehicle (probably due to an earlier replacement of the lockset and where the kept records were not updated), there are then two alternatives:
Remotes – Option one is to have the RR's entire lockset replaced and use the new lockset bar code that comes with it to program an unlocked BECM, Option two is, I can obtain a new remote for you (it would not program into the RR it was originally ordered for); these are only a single remote with its lockset barcode, so if you require a second or third remote you would have to order from a Land Rover dealer. Be sure not to order the same class as the remote you already have, i.e. 1 or 2 etc., as two remotes of the same class cannot be programmed to work at the same time.
Mechanical key - The remotes that I supply (and any ordered from Land Rover) come with a mechanical key, which is for another vehicle, and it will most probably NOT fit your locks. If you supply a non-working remote, I can swap the mechanical key. I also have a supply of blank mechanical keys, which I can get cut, for your locks if you supply a working mechanical key.
Frequency – some markets use 315 MHz and some use 433 MHz – Australia uses both and I need to know what frequency the receiver module in your RR works on. So far, most of the remotes I have been able to obtain have been 315 MHz so if your RR has a 433 MHz receiver it will have to be replaced for use with a new remote.
Repair – I have some spare parts and new cases for the P-38 remotes. Some repairs can be done on remotes that are not corroded or have been water damaged.
