Does the BCM control turn signals?
Meanwhile, on newer vehicles, a computer, which is often referred to as the body control module (BCM), manages the turn signals. When the driver operates the turn signals, an electrical signal is sent to the body control module (BCM).
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 are the symptoms of a defective BCM?
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”). But the BCM may not be able to interpret its meaning as it will not read the sensors accurately. 2. Engine may not start
When does the Body Control Module ( BCM ) fail?
2. When the BCM is exposed to extreme heat, especially during summertime, the function of this system might be undermined and may not give you accurate results. Excessive heat may come from the car’s engine or the surroundings. 3. The BCM could be in danger of failure when your car suffers shock from a collision and other similar accidents.
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 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 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.
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”). But the BCM may not be able to interpret its meaning as it will not read the sensors accurately. 2. Engine may not start
