Pinpoint Test D : P188C And P188D: Notes
NOTE:
Fuse 70 (15A) is HOT at all times and protects multiple components. Check related systems that may be inoperative.
Refer to All Wheel Drive (AWD) for schematic and connector information.
Normal Operation and Fault Conditions
The AWD system uses data from other systems as inputs to the PCM. The PCM uses the inputs to determine the appropriate duty cycle to send to the AWD relay on the command circuit and returns AWD relay information on the feedback circuit.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P188C | AWD Relay Module Communication Circuit | When the PCM detects an open, a short to ground or voltage on the command circuit. |
| P188D | AWD Relay Module Feedback Circuit | When the PCM detects an open, a short to ground or voltage on the feedback circuit. |
