Frequently Asked Questions
What does a Body Control Module do on my Escalade EXT?
The BCM acts as the main computer for your vehicle’s non-engine related electronics. It manages functions like your power windows, door locks, security system, interior and exterior lighting, wipers, and HVAC controls, ensuring they all work together correctly.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills and can often be completed in under 15 minutes. The BCM is usually located under the steering column or driver’s side dash. Disconnecting the battery before you begin is always recommended.
Will this module require programming at the dealership?
No. The primary benefit of our service is that we program the module to your vehicle’s VIN before it ships. This allows for a simple plug-and-play installation without the need for expensive dealer tools or software.
What happens if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag light remains on, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a technician with a professional-grade scan tool.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, the only way to be 100% certain is through proper diagnostics with a scan tool that can communicate with the BCM. Multiple communication-related DTCs or codes pointing to various body systems often confirm a faulty BCM.
What is a core charge, and does this part have one?
A core charge is a deposit you pay until you return your old part. This 2003-2006 Escalade EXT Body Control Module 15137394 has absolutely no core charge, so you can keep your old part without any extra hassle or cost.
