Quick Answer: How Much Does It Cost To Replace BCM??

You will pay around $300 for most cars to replace the body control module.

That includes labor and parts.

The parts will cost about $150, while labor will be closer to $100 or so, depending on how long it takes to rewire the car.

What are the symptoms of a bad body control module?

In case there is some trouble with the BCM, some of the symptoms given below will start showing up in the car. Shaking: The car becomes jerky when driving at increasing speeds. Misfiring: Misfiring of the car at high speeds. Hesitant Acceleration: The pick up of the car, when accelerating, is not smooth.

What causes a BCM to go bad?

Vibration and Stress

Vibration as well as thermal stress has also been known to cause control modules to go bad. This is because they can cause tiny cracks to form in the control module’s circuit boards. However, unlike water damage, this type of damage to a control module is repairable.

How does BCM work?

How Does a BCM Control Unit Work? The body control module receives data from the input devices and controls the output devices based on this data. For instance, when the user presses the power window switch, the car’s battery sends power to the BCM unit, to communicate with the ignition module.

Can BCM be repaired?

Most of the time, a damaged BCM will have to be replaced and can’t be repaired. 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.

Will a bad BCM drain a battery?

When you are on parking, the battery is strong enough to supply your other car components with energy to run them, such as the radio presets, security alarm, and other elements. But a malfunctioning BCM may not detect other parasitic drains that will leave you with a drained battery.

What are signs of a bad alternator?

  • Engine stalling.
  • Dead battery.

Can I put a used BCM in my car?

Q: Can you use a used bcm with out having it reprogrammed

Unfortunately, any control module needs to be flashed or reprogrammed to link to the sensors and monitors of an individual vehicle in order for them to work correctly.

What problems can a bad BCM cause?

Potential causes of a malfunctioning BCM include hard impact collisions, loose wiring harnesses, shorting of wires, excessive heat from the engine, and damaged sensors. These instances can generate multiple problems such as computer miscalculations, which could make your car impossible to drive.
