Normal Operation and Fault Conditions
Description
- Description
- Due to various steering gear hardware versions, a new PSCM must be calibrated or flashed with the correct level of operating software and matching calibration files.
Pinpoint Test Applicability
- Pinpoint Test Applicability
- This test applies to PSCMDTC C1110 only.
This test 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, C200B, 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. Diagnose all current and active Diagnostic Trouble Codes (DTCs) before diagnosing any historic Diagnostic Trouble Codes (DTCs).
Pinpoint Test Purpose
- Pinpoint Test Purpose
- To verify the PSCMDTC C1110 is present and provide diagnostics if DTC C1110 is currently present and active in the PSCM.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |

| PSCM C1110:56 | Power steering Calibration Data: Invalid/Incompatible Configuration | When the PSCM is initialized (ignition ON), the calibration data is checked against the current ECU software version. If the calibration data does not match the software version, this DTC is set. |
