ACDelco 10439803 GM Original Equipment Body Control Module
The Automotive Body Control Module (BCM) is an essential system in your car that controls various body functions. BCMs had become one of the greatest innovations in modern automobiles.
Also known as the ‘body computer’, did you know that a BCM can control power steering, the air-conditioning, and your power windows, among others?
The BCM system is an Electronic Control Unit (ECU) specially designed to manage your vehicle’s processor-based power distribution system. With this device, the works of all electronic modules within the vehicle’s bus are integrated and communicated flawlessly.
We feature here 10 of the best body control module replacement kits available in the market today. Nine of them are from ACDelco, an American automotive parts brand owned by General Motors (GM), and one from Cardone, also an American company well-known as one of the world’s top auto parts manufacturers.
With these world-class brands yet more affordable, you are assured of the highest quality BCMs within your budget.
A body control module functions as your vehicle’s brain. The BCM may seem a small device inside your car but this thing lets you control your vehicle’s body electronics (such as the wiper, power windows, lights, power steering, sensors, HVAC, and side-view mirrors, among others).
The BCM works with your vehicle’s bus system (LIN, CAN, PCAN, etc.) to communicate with different ECUs in your car. However, the BCM doesn’t control any engine-related functions.
Here’s a typical diagram of an auto Body Control Module:
A bad BCM says a lot of symptoms and you should know them very well. Unlike a heater that blows out cold air instead of heat in the middle of freezing weather, BCM failure may trigger a chain reaction.
If not properly addressed, the event can incur large-scale damage to your vehicle. So what are the most visible signs that your BCM is failing?
Here are some of those symptoms:
Exposing your BCM unit from excessive heat (like near the engine or the surroundings) may compromise the BCM’s functions.
Just like any other device or car parts, a BCM unit could suffer the sign of the times. If used for a long time, the system may undergo extreme wear and tears that will lead to its malfunction.
If your vehicle suffers from intense shocks, like in an accident and other similar events, your body control module may suffer the consequences and may lead to failure.
Rainwater and other water sources may contaminate the system and might cause a short circuit of the censors.
If there are problems in the BCM, you can experience these warning signs.
Intense vibration and shaking: Your vehicle may become jerky [to know more about car jerking, read here when accelerating.
Burnt fuse: The fuse box may have a burnt fuse.
Stalling acceleration: If your car is hesitant in accelerating, you may suspect a failing BCM.
Bad engine actuation: You may feel that your engine fails to crank up.
The body control module is usually located under the dashboard on the driver side towards the center of your car. You can look to the right of the steering wheel towards the firewall to find your vehicle’s BCM. A BCM unit is a small black rectangle so you can easily distinguish it from other devices.
Helpful tips: Most of the time, a bad or damaged body control module can’t be repaired or reprogrammed. The different elements (like heat, moisture, vibration, and age) all contribute to the failure of this module.
The best to do is replace the module so a brand new one could provide another long lease of life for your module. A replacement body control module is easily available in online stores so you don’t have to visit a motor shop if you don’t have the time.
A brand new BCM only costs less than a couple of hundred dollars plus a minimal amount for programming and installation as a labor fee from your local dealer. When your car’s BCM fails, take it to a mechanic who can get the job done properly.
Amazon.com offers the most competitive prices for OE (original equipment) BCMs. The store has a wide array of choices for BCMs to fit your car needs.
