Scheme 45

1. CHECK FOR AN ACTIVE DIAGNOSTIC TROUBLE CODE (DTC) Turn the ignition on. With the scan tool, read Park Assist Module DTCs. Does the scan tool display this DTC as active? Yes Go To 2 . No Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) and perform the BODY VERIFICATION TEST.
2. CHECK THE (X700) PARK ASSIST SENSOR SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE Turn the ignition off. Disconnect the Park Assist Module C2 harness connector. Turn the ignition on. Measure the voltage on the (X700) Park Assist Sensor Supply circuit. Is the voltage above 9.2 volts? Yes Repair the (X700) Park Assist Sensor Supply circuit for a short to voltage. Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) and perform the BODY VERIFICATION TEST. No Replace the Park Assist Module in accordance with the Service Information. Refer to «MODULE, PARK ASSIST , REMOVAL»(ref-465950-S32278302072012042300000) . Refer to «STANDARD PROCEDURE»(ref-465990-S29694203322012042300000) and perform the BODY VERIFICATION TEST.
