Diagnostic Overview
C0051:16 or C0051:17
Normal Operation and Fault Conditions
The steering wheel position sensor (also known as the steering wheel rotation sensor) uses 2 optical sensors to monitor the steering wheel position relative to the center position when the ignition is in RUN. The steering wheel position sensor transmits this data to the SCCM (Steering Column Control Module) which processes the data and transmits it on the HS-CAN (High Speed Controller Area Network). When either DTC (Diagnostic Trouble Code) C0051:16 or C0051:17 is set, the SCCM (Steering Column Control Module) ignores the input from the steering wheel position sensor and transmits a fault message on the HS-CAN (High Speed Controller Area Network).
DTC Fault Trigger Conditions
Pinpoint Test
1. CHECK FOR SCCM (Steering Column Control Module) DTCs (Diagnostic Trouble Codes)
1. Using a scan tool, perform SCCM (Steering Column Control Module) self-test.
2. Record all SCCM (Steering Column Control Module) DTCs (Diagnostic Trouble Codes).
Is DTC (Diagnostic Trouble Code) B11D9:16 and/or B11D9:17 present?
2. CHECK THE STEERING WHEEL ANGLE SENSOR STATUS (SW_ANG_SENS) PID (Parameter Identification)
1. Using a scan tool, view SCCM (Steering Column Control Module) PIDs (Parameter Identifications).
2. Monitor the SCCM (Steering Column Control Module) PID (Parameter Identification) SW_ANG_SENS.
Does the PID (Parameter Identification) display CORRECT?
3. CHECK FOR CORRECT SCCM (Steering Column Control Module) OPERATION
1. Disconnect and inspect all SCCM (Steering Column Control Module) connectors.
2. Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
3. Reconnect the SCCM (Steering Column Control Module) connectors and all previously disconnected exterior system connectors. Make sure they seat and latch correctly.
4. Operate the system and determine if the concern is still present.
Is the concern still present?
