Check the fuse box if you suspect that your vehicle’s BCM is on the blink. Make sure all the fuses are in good shape. If any are burnt out, replace them immediately.

How to troubleshoot a Body Control Module ( BCM )?

Turn the radio and CD player on. Sometimes a CD player will stop playing a CD and will begin broadcasting a radio station. The frequency of these actions depends on the severity of the malfunctioning BCM. Check the fuse box if you suspect that your vehicle’s BCM is on the blink. Make sure all the fuses are in good shape.

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

What causes a faulty Body Control Module ( BCM )?

The abnormal vibration that happens frequently will also lead to your BCM to malfunction. Rough roads and other similar terrains where you drive every day may cause the system’s failure. What a Faulty PCM and BCM Can Cause…

What does the BCM stand for in a car?

The BCM, is the body computer that checks in on many of the vital systems of the car and controls theme from a centralized hub.

Why does my BCM fail at high speeds?

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. ● Bad acceleration. If your acceleration isn’t smooth, you could also be experiencing BCM failure.

Can a cup of coffee cause a BCM malfunction?

If liquid gets onto the BCM–sort of like spilling a cup of coffee on your laptop, it can obviously cause some major problems. If it is exposed to a lot of heat or if it freezes and then melts, you can also get BCM malfunctions.

Can a bad ECM cause a car not to start?

4. Car Not Starting. A bad ECM may lead to a vehicle that won’t or is difficult to start. If the ECM fails completely, it will leave the vehicle without engine management control, and will not start or run as a result.

When to seek help for a failing BCM?

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. The key is to heed these warning signs, take prompt action and seek help.

Can a BCM have a no start condition?

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.

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.

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.

How big is a GM body control module?

This computer will fit the following part numbers: 10382479 15093910 15276271 15299986 15819552 15828601 15837419 15872388 15872421 15880684 15921352 15921353 15948438 15948439 20815898 20839063 20864767 20864768 20921435 20921436 20935349 22860591 25826124 25826125 25847588 25847589 25892622 25910474 25934762 25934763 95151084

Why are the indicator lights on my Vue not working?

I have a 2008 Vue and yesterday the indicator lights on the left side of the dashboard came on and won’t turn off (tire pressure, traction control, door ajar, air bag lights, gas gauge didn’t work, didn’t display gear I was in when I shifted out of drive). It was raining out when this happened.

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 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.

How does the BCM work in a starter motor?

The transponder ignition key communicates with the receiver which then communicates the key code to the BCM. The body control module passes the key code on to the PCM for confirmation. If the key code is correct, the PCM sends a verification signal back to the BCM and the BCM supplies power to the control coil on the starter motor relay.

What to do if your car ECM is not working?

The only way to be sure is to visit a mechanic with the proper computer. They can analyze your vehicle’s error codes, and let you know exactly what the problem is. If your ECM can’t make adjustments to your car’s timing or air to fuel ratio, the vehicle may not start at all.
