BCM Programming & RPO Configuration
Replacement BCMs EEPROM chip must be programmed with proper Regular Production Option (RPO) configurations. EEPROM stores vehicle options. When BCM is replaced, replacement BCM must be programmed to identify the following information:
- Country Of Sale (Canada, Europe, US, etc.)
- Daytime Running Lights (DRL)
- Front Fog Lights
- HVAC (C60 Manual Or CJ2 Automatic)
- Memory Options
- Real Time Damping (RTD)
- Tire Pressure Monitor (TPM)
If BCM is not properly programmed, vehicle will exhibit a no crank condition. If BCM is not properly programmed, BCM will set default values for some systems. These default values may cause malfunctions in other systems.
BCM must be programmed to accept resistance value of existing vehicle keys to allow PASS-Key operation. When BCM is replaced, BCM is programmed to accept first PASS-Key resistance value detected. If BCM is unable to detect a valid PASS-Key resistance value, BCM will not end programming sequence and a BCM DTC B2735 will set.
