Description
- Description
- The PSCM continuously monitors different vehicle parameters in order to detect high friction. If the calculated friction value exceeds a predetermined threshold a message is displayed in the message center.
Pinpoint Test Applicability
- Pinpoint Test Applicability
- This test applies to PSCM DTC C102D High Friction Inside Power Steering only. It does not apply to any other module except the PSCM.
DTC Diagnostic Strategy
- DTC Diagnostic Strategy
- If the module DTC list results in a large number of Diagnostic Trouble Codes (DTCs), diagnose all module hard faults first (C102D, C1B00, C200C, C200D, U2011 and U3000) before diagnosing any network faults (lost communication or invalid data). If voltage concern Diagnostic Trouble Codes (DTCs) are present, diagnose those after any module hard faults and before any network faults.
Pinpoint Test Purpose
- Pinpoint Test Purpose
- This test verifies the presence of PSCM DTC C102D and determines if the cause is mechanical or electrical in nature.
Diagnostic Aids
- Diagnostic Aids
- If DTC C102D sets, steering assist is unaffected during the current drive cycle but steering assist is removed starting at the next ignition cycle. Message center displays STEERING LOSS STOP SAFELY.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PSCM C102D:00 | High Friction Inside Power Steering: No Sub Type Information | Sets if high friction is detected inside the steering gear. |
Possible Sources
- Steering gear internal failure
