End the Frustrating Electrical Problems in Your GM Vehicle
Are you dealing with bizarre electrical issues in your car, van, or SUV? Flickering dashboard lights, power windows that won’t cooperate, a security system that acts up, or even a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a nightmare. This isn’t just an inconvenience; it can be a safety concern when lights or locks don’t function as they should.
This replacement Body Control Module, compatible with part numbers 22820314 and 22915542, is the definitive solution. We take the guesswork and high costs out of the repair. Simply provide your vehicle’s VIN at checkout, and our technicians will program the module with the latest GM software specific to your car. It arrives at your door ready for installation, saving you a trip to the dealership and their expensive programming fees. Restore your vehicle’s functionality and your peace of mind with a reliable, ready-to-install part.
From the Diagnostic Bay
I remember a 2015 Traverse that came into the shop with a laundry list of complaints from the owner. The radio would turn on and off, the driver’s side power lock was dead, and the dome light would stay on for minutes after the door was closed. The owner had already replaced the battery and checked fuses. We connected our diagnostic tool and found a slew of ‘Loss of Communication’ codes (U-codes) with various modules. This immediately pointed us toward the BCM. After confirming power and ground to the module were good, we knew the internal logic had failed. Swapping in a pre-programmed 2013-2016 Impala BCM (which also fits the Traverse) resolved every single issue instantly. It’s a classic case of one part causing widespread, confusing problems.
Common Signs of a Failing BCM
- âś” Unpredictable power window or door lock operation.
- âś” Horn honking unexpectedly or not working at all.
- âś” Dashboard warning lights illuminating for no reason (e.g., security light).
- âś” Interior or exterior lights flickering, staying on, or not turning on.
- âś” Communication error codes, such as U0140, U0155, or other U-codes, stored in the system.
- âś” Key fob not being recognized, leading to remote entry/start failure.
- âś” A no-start condition where the engine cranks but won’t fire up due to a security system fault.
A Straightforward Guide to BCM Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- âś” Locate the BCM: On most supported models like the Impala or Acadia, the BCM is located on the driver’s side, up under the dashboard near the steering column. For Express/Savana vans, it’s typically in the center dash area.
- âś” Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have release tabs that need to be pressed. Do not force them.
- âś” Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and remove it. Install the new, pre-programmed module in its place.
- âś” Reconnect Everything: Plug all electrical connectors securely into the new BCM. Reconnect the negative battery terminal.
- âś” Perform Post-Install Procedures: Start the vehicle and check for proper function of all systems. If the airbag light is on or you notice brake system warnings, follow the post-installation procedures outlined below. A professional scan tool may be required for these final steps.
Important Post-Installation Steps
While this module is programmed for a simple installation, some vehicles require a final handshake between modules. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to send you my old BCM?
No. There is no core charge for this part. You can keep your original module.
What does ‘VIN Programmed’ mean?
It means we load the module with your vehicle’s specific software from GM using the Vehicle Identification Number (VIN) you provide. This ensures it works correctly with the options your car came with from the factory.
Will I need special tools for installation?
Basic hand tools are sufficient for physically swapping the module. However, in some cases, a professional-grade diagnostic scan tool is required for post-installation procedures like the airbag system sync or brake pedal relearn.
What happens if my airbag light comes on after I install this?
This indicates the new BCM needs to be synchronized with the airbag module (SDM). A qualified technician with a proper scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this the right part for my 2013-2016 Impala BCM replacement?
Yes, this part (22820314) is a direct replacement for the specified Impala models. It also interchanges with part number 22915542 and fits a wide variety of other GM vehicles as listed in our compatibility chart.
