Restore Full Functionality to Your Vehicle’s Electronics
Are you experiencing frustrating electrical problems in your GMC Terrain, Chevy Equinox, or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a security system that won’t cooperate, 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 hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and disruptive symptoms. This listing offers a reliable, straightforward solution: a replacement BCM programmed specifically for your vehicle.
Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Warning lights appearing on the dashboard without a clear cause.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Unexplained battery drain that leaves you with a dead battery.

Installation & Post-Installation Procedures
The BCM is typically located on the left-hand (driver’s) side of the dash or in the kick panel area. While installation is straightforward, please note the following potential post-installation requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
