Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM

Are you chasing down bizarre electrical gremlins in your GM vehicle? One minute the power windows work, the next they don’t. The security light is flashing for no reason, or your dashboard is lit up with random warning lights. As a technician with over 20 years of experience, I can tell you these aren’t separate problems—they often point to a single failing component: the Body Control Module (BCM). This isn’t just a part; it’s the central nervous system for your vehicle’s comfort and convenience features. When it fails, it creates chaos. We offer a reliable, cost-effective solution: a high-quality replacement Programmed GM Body Control Module, flashed with the latest GM software specifically for your vehicle’s VIN.

Is Your GM Vehicle Showing These Symptoms?

A failing BCM can cause a wide range of issues that might seem unrelated. If you’re experiencing any of the following, your BCM is the likely culprit:

• ✔ Intermittent or non-working power windows, door locks, or mirrors.
• ✔ Erratic interior or exterior lighting (flickering, staying on, or not turning on).
• ✔ Key fob not responding or security system faults.
• ✔ False warnings on the dash, such as “Service StabiliTrak” or “Service Airbag.”
• ✔ Communication DTCs, most commonly U0140 (Lost Communication With Body Control Module).
• ✔ Inconsistent operation of the horn, windshield wipers, or HVAC controls.

Your Straightforward BCM Installation Guide

We handle the complex programming so you can focus on a simple installation. While the BCM location varies by model (check your service manual), the general process is very manageable for a DIYer or professional mechanic.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
2. Locate the BCM: On most of these GM models, the BCM is located under the driver’s side dash, near the steering column or behind a kick panel. On vans like the Express or Savana, it’s often in the center dash area.
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, radio, etc.
6. Perform Relearns (If Needed): Start the vehicle. If an airbag light appears or brake functions seem off, perform the necessary post-installation procedures as detailed below.

Important Post-Installation Information

Because this Programmed GM Body Control Module arrives ready for your vehicle, most functions will work immediately. However, for safety systems, a ‘handshake’ with other modules may be required:

• ✔ 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 compatible pro-level scan tool. This syncs the BCM with the airbag module.
• ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to clear any traction control warnings.
• ✔ No Core Charge: You are not required to send your old BCM back to us. This saves you time and return shipping costs.
