- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 6
- Check for continuity between the (D709) Park Assist Sensor 6 Signal circuit and the (X751) Front Park Assist Sensor Ground circuit at the PTS Module C3 harness connector.
- CHECK THE (D709) PARK ASSIST SENSOR 6 SIGNAL CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
- Disconnect the PTS Module C3 harness connector.
- Measure the resistance of the (D709) Park Assist Sensor 6 Signal circuit between the PTS Module C3 harness connector and the Park Assist Sensor 6 harness connector.
Is the resistance below 3.0 Ohms?
Yes
- Go To 7
No
- Repair the (D709) Park Assist Sensor 6 Signal circuit for an open or high resistance.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- PARK ASSIST SENSOR
- Turn the ignition on.
- Reconnect the PTS Module C3 harness connector.NOTE:
Confirm the following before testing:
- The use of similar gauge wiring.
- Do not use over sized probes/terminals in the connections.
- Connect a jumper wire across the (X702) Front Park Assist Sensor Supply circuit and (D709) Park Assist Sensor 6 Signal circuits at the Park Assist Sensor 6 harness connector.
- Lift Vehicle to a height where the wheels do not touch the ground.
- Turn the ignition on without starting the engine.
- Place the Transmission in reverse.
- With the scan tool, read DTCs.
Does the scan tool display DTC: B1293-12-PTS SENSOR 6- CIRCUIT SHORT TO BATTERY?
Yes
- Replace the Park Assist Sensor in accordance with the Service Information. Refer to SENSOR, PARK ASSIST, REMOVAL AND INSTALLATION .
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 8
- CHECK RELATED HARNESS CONNECTIONS
- Disconnect all PTS Module harness connectors.
- Disconnect all related in-line harness connections (if equipped).
- Disconnect the related component harness connectors.
- Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
- Proper connector installation.
- Damaged connector locks.
- Corrosion.
- Other signs of water intrusion.
- Weather seal damage (if equipped).
- Bent terminals.
- Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
- Terminals that have been pushed back into the connector cavity.
- Perform a terminal drag test on each connector terminal to verify proper terminal tension.
Repair any conditions that are found.
