Body Control Module (BCM) Programming/RPO Configuration: Introduction
A new body control module BCM must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO's available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
- The battery is fully charged.
- The ignition mode switch is in the ON position.
- All disconnected modules and devices are reconnected before programming.
A new BCM installed in the vehicle may set the DTC B1001 00 and DTC C0278 00. This is a normal condition and DTCs will clear after the BCM Setup and BPP Sensor Calibration procedures are performed.
IMPORTANT:
The following procedures must be performed in order when a new BCM is installed. If the procedures are not performed in the order described, the BCM may lock itself.
- BCM Setup
- BPP Sensor Calibration
- Program VIN
