Pinpoint Test C : AWD (All-Wheel Drive) Clutch Control: Notes
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 time to send a signal and have the AWD relay module energize the active torque coupling solenoid.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
