Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 RPOs 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 0. This is a normal condition and DTCs will clear after the BCM Setup and BPP Sensor Calibration procedures are performed.
