Tired of Electrical Gremlins in Your GM SUV?

Expert Insight: The Smart Fix for an Aging System
As a technician, I’ve seen countless GMT360-platform trucks like the Trailblazer and Envoy come in with bizarre electrical issues. Often, these BCMs, located under the rear seat or near the fuse box, suffer from age-related electronic failure or even minor moisture intrusion over the years. In the past, the only option was a new module from the dealer followed by a tow and an expensive programming session. Our solution changes the game. By providing a Programmed 15122670 BCM directly to you, we empower you or your trusted mechanic to complete the repair efficiently, saving hundreds of dollars and significant downtime. It’s the modern, logical repair for a classic, hard-working truck.
Frequently Asked Questions
Do I absolutely have to provide my VIN?
Yes. Providing your Vehicle Identification Number is mandatory. We cannot ship the module without it. The VIN is required to load the correct software and calibration files for your truck’s specific options, ensuring the BCM works correctly upon installation.
Is this BCM truly “plug and play”?
For most vehicles, it is very close. Because it arrives pre-programmed, it eliminates the most difficult step. However, as with any module replacement, certain vehicles may require a simple relearn procedure after installation, such as for the brake pedal position sensor or the airbag system, which can be performed with a compatible high-level scan tool.
What if my airbag light is on after installation?
If the airbag (SRS) warning light appears, it means the new BCM needs to be synced with the vehicle’s airbag control module. A procedure called “Setup SDM Primary Key in BCM” must be performed by a qualified technician with a professional diagnostic tool to resolve this.
How can I be sure my old BCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis is always recommended. This can be done by a professional technician who can check for communication faults and specific BCM-related diagnostic trouble codes (DTCs). A common sign is a scan tool being unable to communicate with the BCM.
Will this fix my intermittent starting problem?
If the starting issue is related to the BCM’s role in the vehicle’s electrical system, then yes, this Programmed 15122670 BCM can resolve it. However, starting problems can have many causes, so it’s important to rule out issues with the battery, starter, and ignition switch first.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
