Frequently Asked Questions
What does this Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, the security system, and the HVAC blower motor, ensuring all your cabin comforts and features work correctly.
Will I need to have this module programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes the installation a simple plug-and-play process, saving you time and the high cost of dealership programming.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM needs to be synced with the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade diagnostic tool.
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. You just need to disconnect the battery, remove a few trim panels, and swap the electrical connectors. The entire process often takes less than 15 minutes.
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.
