Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the climate control system.
Does this BCM require programming at the dealership?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes the installation plug-and-play, saving you time and money by avoiding a trip to the dealer.
Is this part difficult to install?
Installation is generally simple for those with basic mechanical skills. The BCM is typically located under the steering column and can be replaced in under 15 minutes. Always remember to disconnect the battery before starting.
What if my airbag light is on after installing the new BCM?
In some cases, the new BCM needs to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a professional scan tool to clear the light.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which simplifies the repair process for you.
