Frequently Asked Questions
Will I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we pre-program the module to your vehicle’s VIN before shipping. This makes the installation plug-and-play, saving you a costly and time-consuming trip to the dealership.
Where is the BCM located on my Escalade EXT?
On the 2003-2006 Cadillac Escalade EXT and most other compatible GM trucks and SUVs, the Body Control Module is typically located under the driver’s side dashboard, near the steering column. Installation usually takes less than 15 minutes with basic tools.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM needs to be synced with the airbag system’s computer (SDM). If the airbag light stays on, a procedure called “Setup SDM Primary Key in BCM” must be performed with a professional-grade scan tool. This is a simple sync procedure that a qualified technician can complete quickly.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which simplifies the process for you.
