Restore Full Electrical Function to Your Vehicle
Are you battling frustrating and unpredictable electrical problems in your Chevrolet Caprice or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of confusing and disruptive symptoms. This replacement Body Control Module, part number 25910474, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Expert Pro Tip
Before replacing your BCM, always perform a thorough check of your vehicle’s battery and primary ground connections. A weak battery, corroded terminals, or a loose ground wire (especially the main body ground) can cause voltage drops that mimic the symptoms of a faulty BCM. Verifying these components first can save you time and money in your diagnosis.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors behaving erratically or not working at all.
- ✔ The vehicle’s security system engaging randomly or preventing the car from starting.
- ✔ False warnings appearing on the instrument cluster (e.g., ‘Service Theft System’).
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Communication errors with other modules when scanned with a diagnostic tool.
- ✔ Complete loss of power to multiple accessory systems simultaneously.

This process guarantees compatibility and restores all original functions as intended by the manufacturer.
Post-Installation Procedures
While this BCM is programmed for a direct installation, some GM vehicles may require simple relearn procedures after the new module is connected. These are standard processes that help the BCM sync with other vehicle components.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional scan tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, a recalibration of the brake pedal position sensor may be necessary. This ensures the brake lights and traction control system receive accurate data from the BCM.
Please consult a factory service manual or a qualified technician for detailed instructions specific to your vehicle.

Frequently Asked Questions
Do I need to send you my old BCM?
No, there is no core charge for this part. You can keep your original module.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the specific software and configuration files for your vehicle’s exact options. Programming the BCM with this data ensures it works correctly right out of the box, saving you a trip to the dealership.
Is this a difficult part to install?
The physical installation is typically straightforward, involving the removal of a few dash panels and disconnecting electrical connectors. The difficulty level is moderate and can be done by a DIYer with basic tools. However, some models may require post-installation relearn procedures that need a professional scan tool.
What functions does the Body Control Module control?
The BCM manages a wide array of non-engine related functions, including but not limited to: interior and exterior lighting, power windows, power door locks, keyless entry, the security/anti-theft system, and communication between various electronic modules in the vehicle.
Will this fix my ‘Service Theft System’ message?
A failing BCM is a very common cause of a persistent ‘Service Theft System’ warning and related no-start issues. Replacing and correctly programming the BCM is often the correct repair for this problem.
