the EBCM memory. Once all the IDs have been learned and vehicle speed is 25 mph, or greater, Conditions for Running the DTC The ignition is ON. Conditions for Setting the DTC The EBCM has not undergone the programming procedure. Action Taken When the DTC Sets The driver information center (DIC) displays the SERVICE ABS warning message. Conditions for Clearing the DTC A current DTC will clear when the EBCM has undergone the setup procedure. Diagnostic Aids A newly replaced EBCM will set DTC C0569 on its initial ignition ON cycle. Reference Information Scan Tool Reference Control Module References for Scan Tool Information Circuit/System Verification 1. Verify that C0569 is not set as current. If the DTC is set, perform the EBCM setup procedure. Refer to Electronic Brake Repair Procedures Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

Diagnostic Instructions Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Review Strategy Based Diagnosis for an overview of the diagnostic approach. Diagnostic Procedure Instructions provides an overview of each diagnostic category. DTC Descriptor DTC C0710 00 Steering Position Signal DTC C0710 5A Steering Position Signal Plausibility Failure Diagnostic Fault Information Circuit/System Description The steering angle sensor supplies input circuits to the electronic brake control module (EBCM) Conditions for Running the DTC The ignition is ON. Ignition voltage is greater than 9 volts. Conditions for Setting the DTC Opens, short to ground, or short to voltage The calculated steering angle from the steering angle sensor does not correlate with the Circuit Short to Ground Open/High Resistance Short to Voltage Signal Performance Steering Position Signal Circuit C0710 00 C0710 00 C0710 00 C0710 5A

Action Taken When the DTC Sets The EBCM disables the vehicle stability enhancement system (VSES) for the duration of The driver information center (DIC) displays the Service Stability System message. The antilock brake system (ABS) remains functional. The VSES Caution indicator turns ON. Conditions for Clearing the DTC The condition for the DTC is no longer present. The EBCM automatically clears the history DTC when a current DTC is not detected in 100 Diagnostic Aids During diagnosis, park the vehicle on a level surface. Inspect the vehicle for proper alignment. The car should not pull in either direction while Find out from the customer the conditions under which the DTC was set.

Connector Repairs Testing for Intermittent Conditions and Poor Connections Wiring Repairs Scan Tool Reference Control Module References for Scan Tool Information Circuit/System Verification With scan tool installed, clear the DTCs. Turn the steering wheel through its full range and back If the DTC did not set as a current DTC see diagnostic aids. Circuit/System Testing 1. Ignition OFF, disconnect the harness connector at the SAS. 2. Test for less than 2 ohm of resistance between the low reference circuit terminal 2 and ground. If greater than the specified range, test the low reference circuit for an open/high 3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground. If less than the specified range, test the 5-volt reference circuit for a short to ground or 4. Test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and the signal circuit terminal 6. If less than the specified range, test the signal circuit for an open/high resistance. If the 5. Ignition OFF, reconnect the SAS. 6. Disconnect the EBCM harness connector. 7. Test for infinite resistance between the signal circuit pin 6 and ground. If less than the specified range, test the signal circuit for a short to ground. 8. Disconnect the SAS.
