Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, interior and exterior lighting, the security system, and the instrument cluster.
How do I know if my BCM is failing?
Common signs include multiple, unrelated electrical issues happening at once. For example, your power locks and dome light might stop working simultaneously. A persistent security light or a no-start condition where the engine cranks but won’t fire are also strong indicators of a BCM problem on these GM models.
Is this module difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The BCM is typically located under the driver’s side dashboard. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors from the old module to the new one. Since our 2001 GM Truck & SUV Programmed BCM is pre-flashed, no special tools are needed for programming.
Do I need to send you my old BCM?
No. This product comes with no core charge. You can keep your original module without any additional fees or the hassle of shipping it back.
What happens if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag warning light illuminates after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a qualified technician with a professional scan tool.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings specific to your truck’s options and features. This critical step ensures the module works perfectly once installed, just like the original from the factory.
