Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling bizarre electrical gremlins in your Buick LaCrosse, Chevy Malibu, or Cadillac SRX? Flickering lights, malfunctioning power accessories, or a security system that has a mind of its own often point to one central culprit: a failing Body Control Module (BCM). The BCM is the nerve center for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights and anti-theft system. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This listing offers a straightforward, reliable solution: a replacement 2014-2016 LaCrosse Body Control Module that is professionally programmed with your vehicle’s original data.
From the Diagnostic Bay
We had a 2015 Malibu come in with the weirdest issue – the left turn signal would activate the windshield wipers. The customer had replaced switches and relays to no avail. A quick scan showed communication errors with the BCM. After we cloned his original data to one of our replacement modules, all the strange cross-circuit issues vanished. It’s a classic example of how a failing BCM can scramble signals throughout the vehicle, making diagnosis a real headache for the unprepared.
Why Choose Our 2014-2016 LaCrosse Body Control Module Service?
Instead of paying for expensive diagnostics and programming fees at a dealership, our service simplifies the entire process. We perform a direct data transfer (cloning) from your original BCM to this replacement unit. This means the replacement module will be a true plug-and-play part, pre-configured with your car’s specific VIN, options, and key information. There is no need for additional programming or calibration upon installation, saving you time, money, and hassle.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) staying on, flickering, or not turning on.
- ✔ Vehicle security system issues, including false alarms or a no-start condition due to anti-theft activation.
- ✔ Intermittent operation of the radio, climate controls, or windshield wipers.
- ✔ Horn honking unexpectedly.
- ✔ Diagnostic Trouble Codes (DTCs) related to U-codes (communication), B-codes (body), or specific accessory circuits.

Installation and Post-Install Notes
Installation is as simple as disconnecting the battery, removing your old BCM, and plugging in the newly programmed one. However, in some GM vehicles, certain systems may require a relearn or sync procedure after the BCM is replaced. Please be aware of the following:
- 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-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on some models to ensure proper brake light function and to keep the traction control system operating correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic body accessories. This includes power windows, locks, lights, wipers, the security system, and more.
How does your mail-in cloning service work?
After you place your order, you will ship your original BCM to us. We then use specialized equipment to read the unique data from your module and write it onto the replacement unit. This makes the new module a perfect electronic match for your vehicle.
Is this a true plug-and-play solution?
Yes. Because we clone your vehicle’s original data, the replacement BCM will not require any additional programming from a dealer. You simply install it, and it’s ready to go. Some minor relearn procedures, like for the airbag or brake pedal sensor, may be needed in specific cases.
What happens if I have an airbag light after installation?
If the airbag light comes on, it means the BCM needs to be synchronized with the airbag system’s computer (SDM). This is a common security procedure that can be completed by a qualified mechanic with a professional diagnostic tool.
Do I need to return my old BCM after the service?
No core charge is required. We will return your original module along with the newly programmed replacement. You can keep your original part.
