Pinpoint Test BQ: PSCM (Power Steering Control Module) DTC (Diagnostic Trouble Code) U2100:00
WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Power Steering Controls for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Power Steering - System Operation and Component Description .
Description
- When a new EPAS gear is installed, the PSCM 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 10 volts.
Pinpoint Test Applicability
- This test applies to PSCM DTC U2100:00 only. This test 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 verify PSCM U2100 is present and provide diagnostics if DTC U2100 is currently present and active in the PSCM.
Diagnostic Aids
- If DTC U2100:00 is present the steering assist is set to a reduced steering assist mode.
