Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit Vehicle Identification Number (VIN). We cannot ship your module until we receive the VIN, as the programming is specific to your vehicle.
Is this part difficult to install?
The BCM is typically located in or near the under-dash fuse panel. For someone with basic mechanical skills, the physical swap is straightforward. It involves disconnecting the battery, removing some trim panels, and unplugging the old module to plug in the new one. The key benefit of our service is that no post-installation programming is required.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s Supplemental Deployment Module (SDM). If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync that any competent repair shop can perform.
Will this fix my specific electrical problem?
This Programmed 2003-2005 Isuzu Ascender BCM is the solution for a wide range of body-related electrical issues. While it corrects the most common faults, we always recommend proper diagnostics to confirm the BCM is the source of your problem before ordering. This ensures you’re getting the right part for the job.
Do I need to return my old BCM?
No. We do not require you to return your original module. There is no core charge associated with this purchase, which simplifies the process for you.
