Are you battling bizarre electrical problems in your GM vehicle?

Please verify your original part number against the extensive cross-reference list below to confirm compatibility.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (e.g., headlights or dome lights staying on).
- ✔ ‘Service Theft System’ or other security-related warnings on the dash.
- ✔ Key fob not working to lock, unlock, or start the vehicle.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ False dashboard warnings or gauges behaving erratically.
- ✔ Communication (U-codes) or functional faults stored in the vehicle’s diagnostic system.
Installation and Post-Install Considerations
While this BCM is programmed for a plug-and-play installation, some vehicles may require simple relearn procedures after the part is installed. These are typically straightforward but may require a professional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn may be necessary.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
