Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls and monitors many of the non-engine-related electronic accessories in your vehicle. This includes power windows, door locks, interior and exterior lighting, wipers, the security system, and HVAC blower functions.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The BCM is usually located under the driver’s side dashboard near the steering column. Since it comes pre-programmed, the physical replacement is the only step for most functions.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and options into the BCM. This ensures it communicates correctly with all other modules in the vehicle. An unprogrammed module will not function properly and can cause even more electrical issues.
Will this fix my airbag light?
This module often resolves BCM-related airbag codes like B1001. However, in some cases, a post-installation procedure called ‘Setup SDM Primary Key in BCM’ is required using a professional scan tool to sync the new BCM with the airbag system and turn off the light.
Do I need to send my old part back?
No. This BCM comes with no core charge, so you can keep your old part without any hassle or extra fees.
How do I know this is the right BCM for my vehicle?
Please verify that your vehicle is listed in the compatibility chart. The best way to ensure a perfect match is to cross-reference the part number (25844480) or one of the interchangeable numbers with the one on your original module.
