What does BCM mean in fuses?

What does BCM mean in fuses?

In automotive electronics, body control module or ‘body computer’ is a generic term for an electronic control unit responsible for monitoring and controlling various electronic accessories in a vehicle’s body.

Where are the fuses on a 2012 Equinox?

Fuse Box Location It is located on the passenger side panel of the center console.

Why does my ECM fuse keep blowing?

Fuel Pump. Another cause of an ECM 1 fuse consistently blowing is a fuel pump problem. When the fuel pump begins to fail it overheats, causing it to drain more amperage (amp); if the amps exceed the amount of amps the ECM 1 fuse allows, the fuse will blow. Replacing the fuel pump should correct this problem.

Can a bad relay pop a fuse?

I have never seen a relay coil short ciruit that would cause alot of current to flow and therefore blow a fuse. Most common failure with a relay is the actual contacts or less likely the energizing coil goes open circuit and no current flows to energize the contacts.

What problems can a bad BCM cause?

A malfunctioning BCM will activate dashboard instrumentation cluster error and warning lights. These lights may flash off and on if the BCM is not able to read the sensors correctly. Your vehicle performance may also be affected as the BCM communicates with other control modules in the vehicle.

Does a BCM need to be 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. This needs to be completed by a dealer or some automotive specialists, as they control security codes to reprogram these systems.

What happens if ECM fuse is blown?

If an electrical wire gets burned or damaged, the cables pointing to the ECM is going to short-circuit. Once that happens, a power surge can result, and if it the exceeds the fuse’s limitations, the fuse is going to blow. Once you have checked all those spots, check the wires and the coil on the back of the engine.

How do I know if my ECM relay is bad?

Symptoms of a Bad or Failing ECM-Power Relay

  1. No power when the key is inserted. One of the first symptoms of a problem with the ECM power relay is no power when the key is inserted.
  2. Engine will not start.
  3. Battery drain or dead battery.

Can a bad relay cause a dead short?

If the relay has an internal short, it may keep power fed to the ignition and fuel system, even when ignition cylinder is in another position, or the key is removed. This will cause the fuel pump and ignition components to remain powered on, drawing current, at all times, which will eventually lead to a dead battery.

Can a bad relay cause battery drain?

A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off. This will place a parasitic drain on the battery, which will eventually cause it to go dead.
