What Can Cause the Bad Body Control Module Symptoms ? If any of the electrical systems of the car are malfunctioning, it might be time to get the car to a mechanic so that you can get a new body control module. These lights can help you get your car to a mechanic before something seriously wrong happens. What’s the big deal? Why do these symptoms matter? Well, as we saw above, the body control module also controls for warning lights which are supposed to show you when something is malfunctioning inside your car. So, maybe the windshield wipers are proving a bit finicky, or maybe the keyless entry doesn’t seem to be working properly. If a fuse goes bad this could be the BCM. If your acceleration isn’t smooth, you could also be experiencing BCM failure. If the car becomes a bit unstable or misfires when you drive it at high speeds, the BCM might not be communicating and synchronizing different systems of the car. I.e., you could have a check engine light that should be on but isn’t, or you can have a check engine light that is on but shouldn’t be. Flashing dashboard lights, or improper dashboard lighting.Electronics, like windshield wipers and keyless entry, stop working properly.If the keyless entry point of failure is not at the keys or FOB itself, then you should look at the BCM. In fact, the keyless entry is one of the things that can often go wrong in cars that are a little bit older. The keyless entry, especially on newer cars that can open if the keys simply get close enough, is also controlled through the BCM. If you are seeing malfunctions in one or more of these systems and the malfunction doesn’t seem to be occuring at the point of service, the BCM might be involved. Most simple, basic electronic functions that your car has run through the body control module. 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. The windshield wiper system in your car is also connected to the BCM. On the other hand, if your BCM malfunctions, your car might fail to report an actual engine failure. If the check engine lights are coming on and off, the good news is that this might simply be a body control module bcm failure and not an actual engine failure. If the BCM gets out of touch, the dashboard lights might flash on and off, or might go on or off when they are actually not supposed to be triggered. The BCM is supposed to facilitate communication between the vehicle bus of the car and other onboard computers, relaying that information to the user. One of the most technically important things that your body control module is responsible for is the dashboard of warning lights that often appears right around your speed and fuel.
