Is your GM truck or SUV suffering from strange electrical problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and climate controls. When the BCM starts to fail, it can cause a host of confusing and seemingly unrelated issues. This isn’t just an inconvenience; a faulty BCM can lead to a no-start condition or a dead battery, leaving you stranded. This replacement module is the definitive solution to restore full functionality and reliability to your vehicle.
From the Diagnostic Bay
We had a 2002 GMC Yukon in the shop that was driving the owner crazy. The dome lights would flicker randomly, the radio would shut off, and twice the battery was dead overnight. We checked the battery and alternator, which were fine. After running diagnostics, we traced the parasitic draw back to a faulty BCM that wasn’t letting the vehicle’s systems go to sleep. Replacing it with a VIN-programmed unit like this one solved every single issue instantly.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ The security system engaging randomly or preventing the engine from starting.
- ✔ “Service Vehicle Soon” or other warning messages appearing on the dashboard.
- ✔ Intermittent operation of the radio, gauges, or climate control system.
- ✔ Unexplained battery drain that kills the battery overnight.

Post-Installation Information
After installation, some vehicles may require additional simple procedures to sync the new module with other vehicle systems. This is normal. For instance, if your airbag light is on, a professional scan tool will be needed to perform the “Setup SDM Primary Key in BCM” procedure. A Brake Pedal Position relearn may also be necessary on some models to ensure proper brake light and traction control function. Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
This module is a direct replacement for part numbers: 15063578, 15081796, 15095334, 19208537, DKAK, DPNU.

What happens if the airbag light comes on after I install it?
