What is BCM in Ford Edge?
BCM stands for Body Control Module, which is a critical component in the Ford Edge and other Ford vehicles. The BCM is an electronic control unit that manages various body functions and systems in the vehicle.
What is the Body Control Module (BCM)?
The Body Control Module (BCM) is a computer-based system that controls and monitors a variety of electrical and electronic functions in a vehicle. In the Ford Edge, the BCM is responsible for managing features such as the lighting system, power windows, door locks, and other body-related components. It acts as the central nervous system, coordinating the communication between different electronic modules and sensors throughout the vehicle.
Key Functions of the Ford Edge BCM
- Lighting Control: The BCM controls the operation of the headlights, taillights, turn signals, and interior lighting, ensuring they function properly.
- Power Window and Door Lock Control: The BCM manages the power windows and door locks, allowing the driver and passengers to control these features.
- Theft Deterrent System: The BCM is integrated with the vehicle's theft deterrent system, helping to prevent unauthorized access and theft.
- Diagnostic Capabilities: The BCM can diagnose and report issues with various body-related systems, providing valuable information for maintenance and repair.
- Communication with Other Modules: The BCM communicates with other electronic control units (ECUs) in the vehicle, such as the powertrain control module (PCM) and the instrument cluster, to ensure seamless integration and functionality.
The BCM is a crucial component in the Ford Edge, as it ensures the proper operation and coordination of various body systems, contributing to the overall comfort, safety, and reliability of the vehicle.
What does the Ford BCM do?
The BCM communicates with other on-board computers via the car's CAN bus system, and its main application is controlling load drivers – actuating relays that in turn perform actions in the vehicle such as locking the doors, flashing the turn signals (in older cars), or dimming the interior lighting.
Can I replace a BCM myself?
DIY if possible: If you are experienced with car repairs, you might be able to handle the BCM replacement yourself. This could save you the labor costs, which, as we discussed, can be quite useful.
Can I drive with a bad body control module?
The Consequences of Ignoring BCM Problems
A faulty BCM can cause a cascade of malfunctions within the car's electrical systems, leading to the failure of critical components like the air conditioning system, central locking, and dashboard lights, to name a few.
Can I drive with a faulty BCM?
A malfunctioning BCM can lead to irregularities in various vehicle functions and, in severe cases, render your vehicle unsafe for use.
Can I reset my BCM?
Resetting the BCM requires the module's power to be completely drained so that it loses memory, and it usually involves disconnecting the battery and draining the residual power by turning on the headlights.
What causes a control module to go bad?
Common Causes of Engine Control Module Failures
Corrosion on the wiring harness and increased moisture are frequent culprits behind faulty ECMs. These factors can lead to ECM shorts, electric surges, and voltage problems, resulting in inaccurate readings and error codes.
What happens when BCM goes bad?
The BCM can also be the hub responsible for automatically activating certain electronics based on input from certain sensors. A faulty BCM can trigger various issues such as malfunctioning electronics, excess battery drain, and a no-start condition.
How much does it cost to replace a BCM?
between $624 and $659
The average cost for a Body Control Module Replacement is between $624 and $659. Labor costs are estimated between $89 and $112 while parts are priced between $536 and $547. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
How long does it take to reset BCM?
There's a temporary charge that's often stored in the BCM capacitors that needs to be discharged to perform the reset. Touch the disconnected battery cables together, being sure not to touch the battery posts at this time. It should only take a few seconds.
How do I know if my Ford BCM is bad?
Symptoms of a Bad Body Control Module (BCM) Electrical Components Don't Work or Work Erratically Dash Warning Lights Battery Keeps Draining Security System Problems Failure in Driver Assist Systems Communication Failure Codes (U0140) Things Check with a Failed Body Control Module Check Battery and Alternator are Good.
