Frequently Asked Questions
Do I need to take my vehicle to the dealership after installation?
No. Because this 2003-2006 Escalade ESV Body Control Module is pre-programmed to your vehicle’s VIN, you do not need to visit a dealership for additional programming. It is designed to be a plug-and-play solution.
What if my airbag light is on after installing the new BCM?
In some cases, the new BCM may need to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed by a technician with a professional-grade diagnostic scan tool.
Is this module difficult to install?
Installation is generally straightforward for someone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before you begin is always recommended. The entire process often takes less than 10 minutes.
What is a core charge?
A core charge is a deposit that is returned to you when you send back your old part. We do not require a core charge for this BCM, which saves you time and the hassle of shipping your old, faulty module back.
How do I know if the BCM is really the problem?
Common signs of a failing BCM include multiple, unrelated electrical issues like malfunctioning power windows, door locks, interior lights, and HVAC controls. Diagnostic trouble codes related to body systems (often starting with a ‘B’ or ‘U’) are also strong indicators.
