Pinpoint Test J: DTCs C0051:16 and C0051:17

Steering Column Switches

Pinpoint Test J: DTCs C0051:16 and C0051:17

Normal Operation

The Steering Column Control Module (SCCM) continuously monitors the voltage supplied to the steering wheel rotation sensor. The applicable DTC sets if voltage outside of defined limits is detected by the SCCM (Steering Column Control Module).

- DTC C0051:16 (Steering Wheel Position Sensor: Circuit Voltage Below Threshold)- sets if the SCCM (Steering Column Control Module) detects voltage to the steering wheel rotation sensor below 10 volts.

- DTC C0051:17 (Steering Wheel Position Sensor: Circuit Voltage Above Threshold)- sets if the SCCM (Steering Column Control Module) detects voltage to the steering wheel rotation sensor above 15.5 volts.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- High circuit resistance

- Steering wheel rotation sensor

PINPOINT TEST J : DTCs C0051:16 AND C0051:17

NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

J1 CHECK FOR RELATED DTCs

- Review the SCCM (Steering Column Control Module) DTCs retrieved and recorded during Inspection and Verification.

Is DTC B11D9:16 or B11D9:17 present?

Yes
DIAGNOSE DTCs B11D9:16 and B11D9:17 before diagnosing DTCs C0051:16 and C0051:17. For DTCs B11D9:16 and B11D9:17, GO to Pinpoint Test I. Pinpoint Test I: DTCs B11D9:16 and B11D9:17
No
GO to J2.

J2 CHECK THE STEERING WHEEL ANGLE SENSOR STATUS (SW_ANG_SENS) PID

- Enter the following diagnostic mode on the scan tool: SCCM (Steering Column Control Module) DataLogger.

- Monitor the SW_ANG_SENS PID.

Does the PID display CORRECT?

Yes
The condition that caused the DTC to set is not present at this time. CLEAR the DTCs. DRIVE the vehicle for more than 1 minute at a speed greater than 32 km/h (20 mph) and make at least 1 left turn and 1 right turn. REPEAT the self-test.

If DTCs C0051:16 or C0051:17 are present, INSTALL a new SCCM (Steering Column Control Module). REFER to Steering Column Control Module (SCCM) . TEST the system for normal operation.

No
If the PID displays FAULT, INSTALL a new steering wheel rotation sensor. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
