Four-Wheel Drive Systems: Pcm: Notes
DTC Chart: PCM
Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .
Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures, such as module reprogramming, often set network DTCs. Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery. REFER to: Battery .

Normal Operation and Fault Conditions
If the AWD Module observes an overpower or a low voltage condition, a DTC is set and all PTU outputs are turned off.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C0092:17 | 4WD/AWD Power Transfer Unit Position Sensor "B" Circuit Voltage Above Threshold | PTU fork position signal voltage above threshold. |
| C0092:32 | 4WD/AWD Power Transfer Unit Position Sensor "B" Signal Low Time < Minimum | PTU fork position sensor signal out of range. PTU Cam position sensor signal < 3% DC. |
| C0092:33 | 4WD/AWD Power Transfer Unit Position Sensor "B" Signal Low Time > Maximum | PTU fork position sensor signal out of range. PTU Composition sensor signal > 90% DC. |
| C0092:38 | 4WD/AWD Power Transfer Unit Position Sensor "B" Signal Frequency Incorrect | PTU fork position sensor frequency out of range. PTU Cam position sensor frequency out of range 1kHz +/- 150Hz. |
