Are you experiencing perplexing electrical issues in your Chevrolet, GMC, Cadillac, or Buick?

This replacement GM Body Control Module is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN.

Is Your GM Body Control Module Failing?
The BCM is the electronic brain that manages many of your vehicle’s non-engine-related functions. When it starts to fail, the symptoms can seem random and unrelated. Look out for these common warning signs:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning dashboard gauges or warning lights (like the airbag or security light).
- ✔ Problems with the keyless entry or security system.
- ✔ The radio or climate control system behaving unpredictably.
- ✔ A parasitic battery drain that leaves you with a dead battery.
- ✔ A no-start condition where the engine cranks but won’t fire up.

Installation Notes
While this module is designed for a direct fit, some vehicles may require simple post-installation relearn procedures. In most cases, these can be performed with a capable bi-directional scan tool. The two most common procedures are:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as a central computer for your vehicle’s body electronics. It controls features like power windows, locks, lights, wipers, security systems, and interior accessories, ensuring they all work together correctly.
What is the process after I place my order?
After you purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians will then program the BCM with the latest GM software matched specifically to your vehicle before shipping it to you.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. However, as noted, some vehicles may require additional electronic relearn procedures with a proper scan tool for systems like the airbags or brakes.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, yes. However, after installation, the new BCM must be synced with the airbag module (SDM) using a diagnostic tool. If this procedure is not performed, the light will remain on even with the new part.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
