What's a Bcm Fuse?

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.

Does the BCM have a fuse?

BCM can switch power to lights

If the driver left the vehicle with the headlights still on, the current draw would drain the battery. In a vehicle equipped with a BCM, headlight power runs through a headlight relay in the underhood fuse box and then to the headlights.

What happens when a BCM goes bad?

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.
