PINPOINT TEST D : C113A:11 or C113A:15: Notes
Diagnostic Overview
C113A:11 or C113A:15
Normal Operations and Fault Conditions
The wakeup control circuit wakes 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 wakeup control circuit also powers the PATS transceiver. The wakeup control circuit is controlled by the BCM. The wakeup control circuit is FET protected. REFER to Multifunction Electronic Modules , Field Effect Transistor (FET) Protection.
The BCM 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.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C113A:11 | Wakeup Control: Circuit Short To Ground | Set by the BCM when a short to ground is detected on the wakeup control circuit. |
| C113A:15 | Wakeup Control: Circuit Short To Battery or Open | Set by the BCM when a short to voltage or an open is detected on the wakeup control circuit. |
Visual Inspection and Diagnostic Pre-checks
- BCM fuse 18 (10A).
