Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer in your vehicle responsible for managing a wide array of non-engine-related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this module difficult to install?
No, 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. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one in its place. The entire process often takes less than 15 minutes.
Do I need to take my truck to the dealer after installing this?
No. The primary benefit of our service is that this 25844480 Body Control Module comes pre-programmed to your vehicle’s VIN. This eliminates the need for any additional programming or calibration from a dealership, making it a true plug-and-play installation.
How do I know if my BCM is failing?
Common signs of a failing BCM include multiple, unrelated electrical issues happening at once. For example, your radio, power locks, and interior lights might all act erratically. You may also see warning lights on the dash or have diagnostic trouble codes that point to communication errors with various electronic systems.
What happens if the airbag light stays on after installation?
In some cases, particularly if you have an active DTC like B1001, the new BCM needs to sync with the airbag system’s Supplemental Deployment Module (SDM). This requires a professional scan tool to perform a ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any well-equipped automotive shop.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep, discard, or recycle your original module without any need to send it back to us.
