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

Are you chasing down bizarre electrical issues in your GM vehicle? One minute the power windows work, the next they don’t. The security light is flashing, and sometimes the car won’t even start. As a technician with over 20 years of diagnostic experience, I’ve seen these exact frustrations hundreds of time. The culprit is often a failing Body Control Module (BCM), the central command center for your car’s comfort and convenience features. This isn’t just an inconvenience; it affects your vehicle’s core functions and security.

This replacement GM Body Control Module is the definitive, hassle-free solution. We take the guesswork and dealership expense out of the equation. Simply provide your vehicle’s VIN at checkout, and our experts will program the module with the latest official GM software specific to your car or truck. It arrives at your door ready for installation, saving you time and the high cost of dealership programming.

Is Your GM Showing These Symptoms?

A failing BCM can make you feel like your vehicle is possessed. Here are the common signs I see in the shop that point directly to a faulty module:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior dome lights or exterior lamps staying on or not working at all.
• ✔ The security or anti-theft light flashing, often causing a no-start condition.
• ✔ Instrument cluster gauges behaving erratically or going dead.
• ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
• ✔ Remote keyless entry failing to work intermittently or completely.

A Straightforward Guide to Installation

Replacing the BCM is a manageable job for a confident DIYer or a quick task for any professional. With our pre-programmed module, you skip the hardest part.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. Locate the BCM: On most of these GM models, the BCM is located under the driver’s or passenger’s side of the dashboard, or in the center console area. A quick search for your specific model will confirm its location.
3. Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Remove any mounting bolts or clips holding the old module, install the new one, and securely reconnect all electrical plugs.
4. Power Up: Reconnect the negative battery terminal.
5. Perform Relearns: Turn the key to the ‘ON’ position. While the module is plug-and-play, some vehicles may require the post-installation procedures noted below for systems like the airbag or brake sensor.

Important Post-Installation Steps

For a seamless repair, be aware of these potential final steps. Your vehicle may not require them, but it’s important to be prepared.

• Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and requires a professional bi-directional scan tool.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light operation and to keep the traction control system happy.
• No Core Charge: You can keep your old part; there is no core charge and no need to send anything back to us.

Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
