The acronym “BCM” stands for Body Control Module in the context of Ford trucks. The Body Control Module is a computer component in a vehicle that operates, regulates, and checks the vehicle’s electronic devices. It plays an important role in how the electrical features of the vehicle operate. The BCM communicates with other control modules in the vehicle and can affect dashboard instrumentation, warning lights, and vehicle performance. A malfunctioning BCM can activate dashboard error and warning lights, cause battery drain, and result in a no-start condition. It is important to consult factory-specific service literature or a professional mechanic for specific information on the location and resetting procedures for the BCM in your Ford truck .

Is the ECM and BCM the same thing?
What is the main difference between an engine control module (ECM) and a body control module (BCM) on a vehicle? ECM controls the engine, ie ignition timing, fuel injection, , any engine control function. BCM controls the interior and exterior functions of the car.
Can you drive with a bad BCM?
If your car has a problematic BCM, it’s best not to drive it until the BCM is replaced. Control module-related issues can get costly to repair, so you want to avoid aggravating the existing problem. Fortunately, you can get a quality BCM from CarParts.com–and you don’t even have to leave your home for it.
What does a Ford BCM do?
The Electronic Control Module (ECM) is a vital part of any modern engine, using data gathered from the cooling system, intake, exhaust, and other components to deliver commands. It controls ignition timing, wastegate pressure, throttle position, and fuel injection timing.
What does a BCM do in a truck?
MCM controls and regulates all your fuel, timing, EGR and emission components. Located on your engine.
What happens when the BCM goes bad?
Repeated Battery Drain
This draw occurs when a BCM continues to supply power to a particular accessory at incorrect times. Erratic Electrical Function A faulty body control module can also cause intermittent operation of various electrical functions, such as a vehicle’s horn, lights, and wipers.
How do you know if your BCM is bad?
Irregularities in window operation, central locking, dashboard lights, windshield wipers, etc., could be a telltale sign of a failing BCM. Use a Diagnostic Scanner: Connect a diagnostic scanner to the vehicle’s OBD-II port. This device reads error codes that the vehicle’s computer has stored.
How do I know if my Ford BCM is bad?
If your tail lights, turn signal lights, headlights, or cabin lights turn on and off randomly, then a faulty BCM could be to blame.
How much does it cost to replace BCM?
A body control module replacement typically costs anywhere between $400 and $450 on parts alone. Some factors that may affect the price include the brand, series, vehicle specifications, etc. Labor costs can range anywhere from $80 to $100 depending on your vehicle’s year, make, and model.
What does a bad BCM look like?
Unusual door lock and radio operation are additional warning signs of body control module failure, as are dials in the instrument cluster that sweep erratically. When more than one of these symptoms is present at any particular period, the likelihood that such problems are BCM-related rises.
How do I reset my Ford BCM?
Resetting the BCM on a Ford F-150 is as simple as disconnecting or turning off the battery, giving the vehicle a little bit of time and then reconnecting or restarting the battery. Its important to wait at least 15 minutes between draining the vehicle completely and restarting it.
