Are you battling bizarre electrical issues in your GM truck or van? Intermittent power windows, flickering dash lights, a security system that won’t behave, or a mysterious battery drain are all classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it malfunctions, it can create a host of frustrating and hard-to-diagnose problems. This isn’t just a replacement part; it’s a complete, ready-to-install solution for your vehicle.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security or anti-theft light staying illuminated on the dash.
- ✔ Unexplained battery drain that leaves you with a dead vehicle overnight.
- ✔ Remote keyless entry (fob) working intermittently or not at all.
- ✔ Horn honking unexpectedly or not working when pressed.

Installation & Post-Install Notes
Physically replacing the BCM is typically straightforward, often located under the steering column or in the center dash. However, after installation, some vehicles may require additional electronic procedures. If your airbag warning light illuminates, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, the security system, wipers, and the horn.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
Is this part difficult to install?
The physical replacement is a simple plug-and-play process. However, as noted, some vehicles may require additional electronic relearn procedures with a professional scan tool after the new BCM is installed.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
This is a known possibility. The new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Will this Programmed BCM 15194169 fix my vehicle’s battery drain?
If the battery drain is caused by the BCM failing to let other modules ‘sleep’, then yes, replacing it will often solve the problem. However, you should always confirm the BCM is the source of the drain before ordering.
