Restore Command Over Your Vehicle’s Electronics
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster. When the BCM begins to fail, it can cause a cascade of confusing and frustrating electrical problems that can be difficult to diagnose. This replacement Body Control Module is the definitive solution to restore full functionality and reliability to your vehicle.
From the Diagnostic Bay
We had a 2011 Savana work van come in that was driving the owner crazy. The dome lights would flicker randomly, the radio would shut off, and sometimes the battery would be dead overnight. The owner had already replaced the battery and alternator with no luck. After a quick scan, we saw multiple communication errors pointing to the BCM. A failing BCM was causing a parasitic draw, draining the battery. Installing a VIN-programmed module like this one solved all the gremlins in one go, saving the owner from further guesswork and costly repairs.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Intermittent no-start conditions or a security light that stays illuminated.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Problems with the heating and A/C blower motor controls.

Post-Installation Information
While this module is programmed for your VIN, some vehicle systems may require a relearn procedure after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
- Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician for your specific vehicle.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before shipping it to you. It will arrive ready to install, saving you time and money.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the part until we receive this information.
What does the BCM actually control?
The Body Control Module manages a wide range of non-engine related functions, including power windows, locks, interior/exterior lighting, the security system, wipers, and climate control fans.
What if the airbag light comes on after I install it?
This can happen occasionally. The new BCM needs to be synced with the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
