VE BCM key coding - is it a one time deal?

Postby Gareth » Thu Aug 13, 2015 8:03 am

as the title suggests, I have a VE in next week for a replacement BCM (brake light circuit death..) so I've never done a BCM in a VE and was wondering if I need to order new keys to go with it (like VR-VY), any thoughts are appreciated :thumbup:

Trying to remember years ago having a play with the tech2 on a VE and programming a spare key.
It showed counts of how many times a key was programmed, can't remember the limit.
Maybe do a brake pedal position relearn before ordering a bcm (not sure if you have already checked that)

Programming the BCM
Note: The vehicle will not start and many other functions may not operate correctly if a replacement BCM is not correctly set up. The following procedures must be followed:

 1. The BCM reprogramming – Refer to Service Programming System (SPS).
 2. Brake pedal position sensor (BPPS) learn.
 3. Program SDM primary key to BCM
Note: After the procedure is completed, the personalization settings of the BCM are set to default settings. Inform the customer that the personalization must be set again.

Brake Pedal Position Sensor (BPPS) Learn
 1. Calibration Criteria DO NOT apply the brake pedal during the brake pedal position sensor calibration procedure. Any movement of the brake pedal during this procedure will cause the calibration procedure to fail. If this occurs, the BPPS calibration must be repeated. BPPS calibration must be performed after the BPPS or body control module (BCM) have been serviced. The calibration procedure will set the BPPS home value. This value is used by the BCM to determine the action of the driver applying the brake system and to provide this information to the vehicle subsystems via the serial data communication bus.
Apply the parking brake.

 2. Place the transmission in the PARK position for automatic transmission or NEUTRAL for manual transmission.
 3. Install a diagnostic scan tool.
 4. Key ON, engine OFF, select Body.
 5. Select BCM (Body Control Module).
 6. Select Programming.
 7. Select the Brake Pedal Position Sensor Learn procedure and follow the directions displayed on the screen.
 8. Check all vehicle lights for correct operation.
Program SDM Primary Key to BCM
 1. Install a diagnostic scan tool.
 2. Key ON, engine OFF, select Body.
 3. Select BCM (Body Control Module).
 4. Select Programming.
 5. Select the Program SDM primary key to BCM procedure and follow the directions displayed on the screen.

You will need the ability to change the Vin number in the BCM, Tech2 and SPS can do it or, not sure about other scan tools :thumbup:
