Restore Full Electrical Function to Your Vehicle
The Body Control Module (BCM) acts as the central command center for your vehicle’s electronic accessories. It controls everything from power windows and door locks to the security system and interior lighting. When the BCM fails, it can cause a wide array of confusing and intermittent electrical issues, making your vehicle unreliable. This replacement Body Control Module is the definitive solution, delivered to you pre-programmed with the latest GM software matched specifically to your vehicle’s VIN.
From the Diagnostic Bay
We recently serviced a 2011 Cadillac CTS with a classic BCM failure. The owner reported that the interior dome lights would randomly stay on, draining the battery, and the key fob would only work sporadically. After confirming power and ground to the module were good, we diagnosed a faulty BCM. Swapping in a VIN-programmed module like this one instantly resolved all the electrical gremlins, saving the customer a significant amount of money and time compared to a dealership visit.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights failing to turn on or off correctly.
- ✔ The anti-theft or security system malfunctioning, possibly preventing the engine from starting.
- ✔ Keyless entry remote (key fob) not working reliably.
- ✔ Unexplained warning lights appearing on the instrument cluster.
- ✔ Radio, climate controls, or other interior accessories behaving strangely.
- ✔ A “Service Electrical System” message appearing on the dash.

Important Post-Installation Information
While this module is programmed for a direct fit, certain vehicle systems may require a quick synchronization procedure after installation to communicate properly with the new BCM. Please be aware of these potential requirements:
- Airbag System Sync: If the airbag warning light comes on after installation, the ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional diagnostic tool to sync the system and turn off the light. This is only required if the light is on.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on some models to ensure proper brake light function and traction control system performance.
There is no core charge for this part. You can keep your original module.
Frequently Asked Questions
What is a Body Control Module and what does it do?
The Body Control Module, or BCM, is a computer that manages and monitors many of your vehicle’s non-engine related electronic systems, such as lighting, power accessories, security, and climate controls.
Why do you need my VIN?
Your 17-digit Vehicle Identification Number (VIN) allows us to load the exact software and configuration for your vehicle’s specific features and options. This ensures the BCM works correctly right out of the box without requiring a trip to the dealer for programming.
Is this BCM difficult to install?
The physical installation is generally straightforward for someone with basic mechanical skills, as it’s typically located under the dash and involves unplugging the old module and plugging in the new one. Our VIN programming eliminates the most difficult part of the job.
Will I need to visit a mechanic after installation?
In most cases, no. However, if your vehicle’s airbag light comes on, it will require a ‘Setup SDM’ procedure with a professional scan tool to sync the systems. This can be performed by most independent repair shops.
My original part has a different number. Will this work?
Yes. Vehicle manufacturers often supersede part numbers. This module is a verified replacement for the extensive list of part numbers shown in the description, covering a wide range of GM cars, trucks, and SUVs.
