2011-2012 LaCrosse BCM Body Control Module 13586278 Programmed

Is Your GM Vehicle Acting Possessed?

If your 2011-2012 Buick LaCrosse, Chevy Volt, Cadillac SRX, or other compatible GM model is plagued by bizarre electrical issues, the Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lights and security system. When it begins to fail, it can create a cascade of frustrating and seemingly unrelated problems that can be difficult to diagnose.

Common Symptoms of a Failing BCM

A faulty BCM doesn’t always fail completely. Often, it will cause intermittent issues that come and go with temperature changes or vehicle vibration. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs attention:

• ✔ Power windows, door locks, or mirrors operating erratically or not at all.
• ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
• ✔ The vehicle’s security system engaging randomly or preventing the car from starting.
• ✔ Key fobs that stop working intermittently.
• ✔ Unexplained battery drain that leaves you with a dead battery overnight.
• ✔ Warning lights on the dashboard (like the airbag or service vehicle light) with no other apparent cause.
• ✔ The radio or climate control system behaving unpredictably.

The Easiest Solution: Our Plug-and-Play Programming Service

Replacing a BCM isn’t as simple as swapping the part. A new module from the dealership must be programmed with expensive, specialized tools to recognize your vehicle’s specific key data and options. Our unique cloning service eliminates this entire step. We provide a simple, cost-effective solution to get your vehicle back to perfect working order without a trip to the dealer.

The process is straightforward:

1. Place Your Order: Purchase this service and we will contact you with shipping instructions.
2. Ship Us Your Original BCM: Carefully package and send your vehicle’s original BCM to us.
3. We Clone The Data: Our technicians will extract the vital, vehicle-specific data from your original module and flash it onto a fully tested replacement unit.
4. Receive Your Programmed BCM: We ship the replacement, programmed module back to you. The unit you receive is 100% plug-and-play, ready for installation.

Installation and Post-Install Notes for your 2011-2012 LaCrosse BCM

Because we’ve transferred all the necessary data, installation is as simple as disconnecting the battery, removing the old module, and plugging in the new one. However, in some GM vehicles, a couple of minor follow-up procedures may be necessary.

• Airbag System Sync: If the airbag warning light appears after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be required to ensure correct brake light function and to satisfy the traction control system.
