Pinpoint Test Y: PSCM (Power Steering Control Module) DTC (Diagnostic Trouble Code) U2100:00 Initial Configuration Not Complete

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 U2100 Initial 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 U2100 is present and provide diagnostics if DTC U2100 is currently active in the PSCM.

Diagnostic Aids 

• REFER to: Module Configuration - System Operation and Component Description .

DTC Fault Trigger Conditions 

Possible Sources 

• PSCM not configured
• PSCM configuration not complete

Visual Inspection and Pre-checks 

• This DTC is set if the complete PSCM configuration was not carried out or if the configuration fails.

1. NOTE: This procedure must be completed using FDRS. Do not clear DTCs until the FDRS procedure has completed.To complete the diagnosis, navigate to the FDRS Guided Routine tab and carry out the procedure
