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.
Can a BCM have a no start condition?
Because of the BCM’s communications with other modules and components you may experience a no crank or no start condition. In many cases, your BCM will alert you to issues with symptoms, warning lights or both.

Is the windshield wiper connected to the BCM?
The windshield wiper system in your car is also connected to the BCM. Your body control module also controls the power windows, air conditioning, the immobilizer system, the central electronic locking of the car, and the movement of the mirrors. Most simple, basic electronic functions that your car has run through the body control module.
Why is my BCM not working on my car?
Some of the possible causes of a malfunctioning BCM include the clock on the radio not keeping its time and reverting to 12:00 when the vehicle is turned off, then turned on again. Check to make sure all the electronic devices are working properly. If you use a key fob to lock and unlock the doors, the function may not work.
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.

What are the symptoms of a failing BCM?
5 Common Symptoms of a Failing Body Control Module (BCM) 1 The Intermittent Operation of Electronic Components. 2 Security Function Errors. 3 Check Engine Light (CEL) or Other Instrumentation Cluster Warning Lights. 4 Battery Drain (Parasitic drain). 5 No Start Condition.
Can a BCM switch turn off the headlights?
If so, the BCM can turn off the headlights to save battery power. In more complicated and more recent designs, car makers run a single wire to the multi function switch to control headlights, high beams, parking lamps, turn signals and hazards. How can they accomplish all that with a single wire? Simple, the switch contains several resistors.
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.
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.
What is the code for the BCM BCM?
Code U0140 pertains to the BCM or the wiring to the BCM from the engine control module (ECM).
If so, the BCM can turn off the headlights to save battery power. In more complicated and more recent designs, car makers run a single wire to the multi function switch to control headlights, high beams, parking lamps, turn signals and hazards. How can they accomplish all that with a single wire? Simple, the switch contains several resistors.
Can a bad BCM cause a car not to start?
Apart from the symptoms above, you may also notice general instability (i.e., your car shakes upon acceleration) when you have code U0140. The code typically appears when diagnosing cars with engine misfires, water-logged sensors, and shorting of wires due to breakage.
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.
When to ignore a bad body control module?
If your control module bcm malfunctions, it can either actively cause damage to your car by messing up the systems that it controls or passively cause damage to your car by failing to alert you about systems that are malfunctioning. Needless to say, you never want to ignore certain body control module problems.
