PINPOINT TEST L : C0051:16 or C0051:17: Notes
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 which processes the data and transmits it on the HS-CAN. When either DTC C0051:16 or C0051:17 is set, the SCCM ignores the input from the steering wheel position sensor and transmits a fault message on the HS-CAN.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C0051:16 | Steering Wheel Position Sensor: Circuit Voltage Below Threshold | This DTC sets if the data received by the SCCM from either of the 2 optical sensors is below a predetermined threshold. |
| C0051:17 | Steering Wheel Position Sensor: Circuit Voltage Above Threshold | If the data received by the SCCM from either of the 2 optical sensors is above a predetermined threshold. |
