Power Modes

The Body Control Module/Gateway Module (BCM/GWM) assembly controls the power supplies for the various vehicle functions. There are nine power modes available to determine the operating condition of the vehicle.

Only five of these modes will be noticeable to the driver and technicians as follows:

• Power mode 0 - Ignition off
• Power mode 4 - Accessory
• Power mode 6 - Ignition on
• Power mode 7 - Engine running
• Power mode 9 - Crank before engine running.
