Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing frustrating electrical issues in your 2011-2013 Chevrolet Caprice or other compatible GM vehicle? Symptoms like malfunctioning power windows, erratic dashboard lights, a faulty security system, or unresponsive interior accessories often point to a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and disruptive problems. This replacement Body Control Module, part number 25847588, is the definitive solution to restore your vehicle’s proper operation.
From the Diagnostic Bay
We had a 2012 Caprice PPV (Police Pursuit Vehicle) in the shop that was draining its battery overnight. The owner had already replaced the battery and alternator, but the parasitic draw persisted. After hours of tracing circuits, we found the culprit: the original BCM had an internal short that was keeping the fuel pump relay energized even when the car was off. Swapping in a correctly programmed BCM not only fixed the battery drain but also resolved an intermittent power lock issue the owner hadn’t even mentioned. It highlights how a single faulty module can cause multiple, seemingly unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Erratic or flickering dashboard warning lights (ABS, Airbag, Security).
- ✔ Vehicle’s anti-theft system preventing the car from starting.
- ✔ Interior or exterior lights staying on, draining the battery, or not turning on.
- ✔ Horn, radio, or windshield wipers activating unexpectedly.
- ✔ Inability for a scan tool to communicate with the module.

This ensures a seamless installation process, getting you back on the road faster. This module is a direct replacement for a wide range of part numbers, including: 15826125, 25847589, 25892622, 20815898, 22860591, and many more.
Installation and Post-Install Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps after the part is connected. These are known as relearn procedures and are necessary to sync the new BCM with other modules in your vehicle.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and to satisfy the traction control system.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
