BCM Replacement and Programming
Proceed as follows to program and configure a BCM:
- Open the Service Programming System (SPS) with a scan tool and follow the instructions on the screen. See SERVICE PROGRAMMING SYSTEM (SPS) .
- Select BCM body control module - Programming on the monitoring screen with SPS support and follow the instructions on the screen.
- Perform the following for the right type of ignition system before continuing with the next step:
- Key ignition system: Key in ignition. Other keys to the car must be at least 3 metres from the car.
- Press the start system button: The remote control key must sit in the console's programming pocket. You can display info on the exact position of the pocket using the Help button in the window SPS Immobilizer Setup. All other remote control keys must be at least 3 metres from the car.

NOTE: The following programming steps can take between 10 and 12 minutes and it may seem like the process has stopped during that time. This is a normal security timeout response. Do not restart programming.
