What can cause a BCM module to fail?
Water, vibration, heat and age can all contribute to a module failing, which, depending on the placement of the unit in your vehicle, can be difficult to avoid. To keep your new BCM in the best shape possible, make sure it stays clean and dry, and protect it from unwanted shaking or excessive heat if at all possible.
What happens when a BCM goes bad in a car?
As the BCM is communicating with other control elements of your car, its accomplishments of various functions may be hindered. For example, a defective BCM may trigger dashboard instrumentation cluster error and the car’s warning lights may flash on and off (such as the “check engine light”).
What is the Body Control Module ( BCM ) in a car?
You’ve probably never thought about the body control module (BCM) in your car, but this component plays an important and comprehensive role in how the electrical features of your vehicle operate. Since the BCM touches on so many different systems, it’s not always obvious when things start to go awry.
Why does my BCM say no start?
A “no crank” or no start status on the engine may be observed when the BCM malfunctions. This is primarily because of the BCM’s miscommunication with other control systems of the vehicle.

What does the Body Control Module ( BCM ) do?
The Body Control Module (BCM) is the central organizational element of your car that controls other security systems of the vehicle. The BCM contains information which lets you know directly concerning a system that is malfunctioning and out of control.
How does the BCM connect to the PCM?
It says the bcm is the Power Mode Master (PMM) and controls all other modules including the pcm (on my truck anyway). The wiring diagrams show there is no direct link between the pcm and the diagnostic link connector, it shows the pcm connects directly to the bcm which then connects to the dlc.
What happens if a BCM module goes bad?
A bad BCM body control module can prevent you from scanning for trouble codes, kill your digital instrument cluster and gas gauge, and prevent you from turning on lights or starting the engine. In the early days, replacing a bad body control module meant paying a small fortune for a new one from a dealer. That’s not the case anymore.
