Normal Operation and Fault Conditions
The wake-up control circuit wakes up the PCM and the SOBDMC/ TCM prior to engine cranking/torque request. The PCM and SOBDMC/ TCM needs to wake up prior to a crank/torque request so they have the time to go through their initialization. The wake-up control circuit is controlled by the BCM.
The BCM activates the wake-up control circuit when any of the following occur:
- The driver door is opened
- A key is inserted into the ignition
- The ignition is in the ON or START position
