Normal Operation
The wake up control circuit is used to wake up the PCM prior to engine cranking. The PCM needs to wake up prior to a crank request so that it has time to go through its initialization. The wake up control circuit is also used to power the Passive Anti-Theft System (PATS) transceiver. The wake up control circuit is controlled by the Body Control Module (BCM) and receives voltage from fuse 18 (10A).
The BCM activates the wake up 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.
- DTC C113A:11 (Wake up Control: Circuit Short To Ground) - sets when the BCM detects a short to ground on the wake up control circuit. The
- DTC C113A:15 (Wake up Control: Circuit Short To Battery or Open) - sets when the BCM detects a short to voltage or an open on the wake up control circuit.
- DTC U1000:00 (Solid State Driver Protection Activated - Driver Disabled: No Sub Type Information) - sets when the BCM has temporarily shut down the output driver. The module has temporarily disabled the wake up control circuit because an excessive current draw exists (such as a short to ground). The BCM cannot enable the wake up control circuit until the cause of the short is corrected, the DTCs have been cleared and a successful self-test is run.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- PATS transceiver
- PCM
- BCM
