Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, these systems can behave erratically.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific configuration and security information onto the BCM. Without it, the module won’t recognize your vehicle’s features or communicate correctly with other onboard computers, leading to system malfunctions or a no-start condition. Our pre-programming service makes the installation plug-and-play.
How difficult is the installation?
The physical installation is straightforward for someone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard near the steering column. The process usually takes less than 15 minutes. However, be aware of potential post-installation procedures noted in the product details.
My airbag light is on. Will this BCM fix it?
A faulty BCM can cause an airbag light, often with code B1001. While this replacement 22860591 Body Control Module will resolve the hardware fault, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and clear the light after installation.
What does “No Core Charge” mean?
It means you are not required to send your old, failed BCM back to us. This saves you the time, hassle, and expense of return shipping and waiting for a core deposit refund.
