Normal Operations and Fault Conditions

The wakeup control circuit wakes up the PCM (Powertrain Control Module) prior to engine cranking. The PCM (Powertrain Control Module) needs to wake up prior to a crank request so that it has time to go through its initialization. The wakeup control circuit also powers the PATS (Passive Anti-Theft System) transceiver. The wakeup control circuit is controlled by the BCM (Body Control Module). The wakeup control circuit is FET (Field-Effect Transistor) protected. REFER to Field Effect Transistor (FET) Protection Description and Operation for additional information.

The BCM (Body Control Module) activates the wakeup control circuit when:
- the driver door is opened.
- a remote start request is received (if equipped with factory remote start).
- the brake pedal is pressed.
- a key is inserted into the ignition.
- or when the ignition is in the RUN or START position.
