Diagnostic Trouble Code (DTC) C0710 Steering Wheel Position Sensor (SWPS) Signal, Service Stability System Message on Driver Information Center (DIC) (Inspect and Secure Wires in SWPS Connector)

This bulletin is being revised to clarify connector numbers (Step 3). Please discard Corporate Bulletin Number 06-02-35-002 (Section 02-Steering).

Some customers may comment on a Service Stability Message on the DIC.

Diagnosis with a scan tool may reveal a DTC C0710.

The most likely cause of a DTC C0710 on a vehicle equipped with telescoping/tilt steering wheel is high resistance in SWPS connector C202. Fretting terminal corrosion maybe present in the SWPS connector due to the telescoping motion of the steering column. When the steering column is telescoped in and out, the female terminals within the SWPS connector may move on the male terminals of the SWPS. This movement between the terminals may cause a high resistance condition in the SWPS connector.

1. Remove the driver's side close out panel.

•	Cadillac XLR -- Refer to Closeout/Insulator Panel Replacement - Left

•	Chevrolet Corvette -- Refer to Closeout/Insulator Panel Replacement - Instrument Panel (I/P) Lower




2. On XLR models only, locate and remove the plastic strap (1) on the steering column harness that retains the three wiring harnesses. Discard this strap.

Important: Connector C202 is specified by the supplier and does not appear on the wiring schematic. This connector is different from C231 (40 pin) which does appear on the schematic.

3. Disconnect the SWPS connector C202 which connects to the steering angle sensor located on the lower center of the steering column.

Important: 

•	Failure to properly tape the wires in the connector may result in additional concerns.

•	Failure to use a small plastic strap 2.5-3.5 mm (0.10-0.14 in) in width may prevent the SWPS connector from properly seating, resulting in additional SWPS DTCs.

•	Failure to position the plastic strap in the connector notch shown below may result in the strap becoming loose and allowing the terminal to move within the connector.




4. Using electrical tape (1), tape from the plastic strap up the wires a minimum of 2.5 cm (1 in).
5. Install a small plastic strap (2) 2.5-3.5 mm (0.10-0.14 in) wide around the SWPS sensor connector so that it retains the wires to the connector as shown.

Important: Install and remove the SWPS connector a minimum of three times to remove any possible terminal corrosion.

6. Reinstall the SWPS connector.
7. Reinstall the close out panel.

•	Cadillac XLR -- Refer to Closeout/Insulator Panel Replacement - Left

•	Chevrolet Corvette -- Refer to Closeout/Insulator Panel Replacement - Instrument Panel (I/P) Lower

8. Clear the DTC with a scan tool and road test the vehicle.
9. If DTC C0710 resets during the road test, refer to DTC C0710 in SI.
