Pinpoint Test R: PSCM (Power Steering Control Module) DTC (Diagnostic Trouble Code) C200D:62 Motor Rotation Angle Sensor: Signal Compare Failure
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- NOTE: Refer to Steering GSB for additional connector and wiring inspection tips.
Refer to Wiring Diagrams POWER STEERING CONTROLS for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Power Steering - Overview .
Description
- The PSCM continually monitors the motor position angle sensor when the ignition is ON and the voltage supply to the PSCM is above 5.46 volts.
Pinpoint Test Applicability
- This test applies to PSCMDTC C200D:62 Motor Rotation Angle Sensor only. It does not apply to any other module except 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 C200D:62 is present and provide diagnostics if DTC C200D:62 is currently present and active in the PSCM.
Diagnostic Aids
- During the ignition cycle the DTC initially sets, the PSCM enters limp home mode. The PSCM sends a message to the IPC to display the
STEERING ASSIST FAULT SERVICE REQUIRED in the message center.
- During the next ignition cycle after the DTC sets, if the concern is still present, the PSCM removes steering assist and enters manual mode. The module also transmits an invalid steering angle message over the HS-CAN and sends a message to the IPC to display the
STEERING ASSIST FAULT SERVICE REQUIRED in the message center.
- If a damaged bellows boot(s) was discovered during inspection and this pinpoint test
DOES NOT lead to the installation of a new EPAS gear or bellows boot(s), then ADDRESS the damaged boot(s) before returning the vehicle to the customer.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition PSCM C200D:62 Motor Rotation Angle Sensor: Signal Compare Failure This DTC sets when the steering torque sensor input to the PSCM is out of range or does not agree with other PSCM inputs. This is most likely due to internal faults in the PSCM. Possible Sources
- Steering gear internal failure
- NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
- COMPLETE THE FDRS GUIDED ROUTINE
- 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
