Pinpoint Test Ab: PSCM (Power Steering Control Module) DTC (Diagnostic Trouble Code) U2300 Central Configuration
Normal Operation and Fault Conditions
- Description
- When a new EPAS gear is installed, the PSCM is blank and must be configured with the vehicle information. Configuration is checked during initial PSCM power up (ignition ON) with the voltage supply to the PSCM greater than 6 volts.
- Pinpoint Test Applicability
- This test applies to PSCMDTC U2300 Central Configuration not complete only. It does not apply to any other module except the PSCM.
- 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
- To verifyPSCMDTC U2300 is present and provide diagnostics if DTC U2300 is currently active in the PSCM.

DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PSCM U2300:55 | Central Configuration: Not Configured | This DTC is set if the initial PSCM configuration was not carried out or if the configuration fails. |
| PSCM U2300:56 | Central Configuration: Invalid/Incompatible Configuration | This DTC is set if the initial PSCM configuration was not carried out correctly or if the configuration was not completed. |
