Post-Installation Information
While this module is designed for a simple installation, some vehicles may require additional steps to sync all systems. If your airbag warning light illuminates after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on certain models to ensure correct brake light and traction control operation. Always consult a factory service manual for your specific vehicle.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security systems, and climate controls.
How do I know if my BCM is the problem?
Common symptoms include multiple, unrelated electrical issues happening at once, such as lights flickering, windows not working, and security system faults. A professional diagnosis is the best way to confirm, but these symptoms are strong indicators of BCM failure.
Is this part difficult to install?
For most models, the BCM is located under the dashboard and is a plug-and-play part. It typically involves removing a few trim panels and disconnecting electrical connectors. Basic hand tools are usually all that’s required.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
What if my airbag light is on after I install the new BCM?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade diagnostic tool to sync the modules and turn off the light.
