Condition
Some customers may comment on a Stabilitrak(R) or Active Handling System light being illuminated. Also, this warning light will be accompanied by a SERVICE STABILITRAK or SERVICE ACTIVE HNDLG message on the DIC. Diagnosis with a scan tool may reveal a DTC C0710.
Cause
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 may be 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.
Correction
Remove the drivers side closeout (insulator) panel.
Locate the SWPS connector that connects to the steering angle sensor, located on the lower center of the steering column.
Install the clip (1), P/N 19179794, into the connector. This clip will act as a terminal positive assurance (TPA) and prevent any movement of the terminals.
Reinstall the closeout panel.
Clear the DTC with a scan tool and road test the vehicle.
If DTC C0710 resets during the road test, refer to DTC C0710 in SI.
