Power Mode Defined

The power mode is the information used by the various control modules on the vehicle to determine operation. The power mode reflects the ignition switch position as well as any power modes that are customer convenience items, i. e. Retained Accessory Power (RAP). If a control module does not receive a power mode signal, either a serial data message or a hard wire input, the control module does not operate.
