Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. Verify the Park Assist Sensor is connected before proceeding with this diagnostic procedure.
  NOTE:
  A disconnected sensor will set this DTC.
2. With the scan tool, read PAM DTCs and record on the repair order.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read PAM DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - 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. If no problems are found, test complete.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK THE VOLTAGE OF THE (X700) PARK ASSIST SENSOR SUPPLY CIRCUIT

1. Check for continuity between ground and the (D701) Park Assist Sensor 8 Signal circuit at the Park Assist Module C2 harness connector.
  Is there continuity between ground and the (D701) Park Assist Sensor 8 Signal circuit?
  
  Yes
  - Go To 5
  No
  - Go To 7
CHECK THE (D701) PARK ASSIST SENSOR 8 SIGNAL CIRCUIT FOR A SHORT TO GROUND WITH THE PARK ASSIST MODULE DISCONNECTED
1. Disconnect the Park Assist Module C2 harness connector.
2. Check for continuity between ground and the (D701) Park Assist Sensor 8 Signal circuit at the Park Assist Module C2 harness connector.
  Is there continuity between ground and the (D701) Park Assist Sensor 8 Signal circuit?
  
  Yes
  - Repair the (D701) Park Assist Sensor 8 Signal circuit for a short to ground.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 6
CHECK THE (D701) PARK ASSIST SENSOR 8 SIGNAL CIRCUIT FOR A SHORT TO THE (X750) PARK ASSIST SENSOR GROUND CIRCUIT
1. Check for continuity between the (D701) Park Assist Sensor 8 Signal circuit and the (X750) Park Assist Sensor Ground circuit at the Park Assist Module C2 harness connector.
  Is there continuity between the (D701) Park Assist Sensor 8 Signal circuit and the (X750) Park Assist Sensor Ground circuit?
  
  Yes
  - Repair the (D701) Park Assist Sensor 8 Signal circuit and the (X750) Park Assist Sensor Ground circuit for a short together.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Replace the Park Assist Module in accordance with the Service Information. Refer to MODULE, PARK ASSIST, REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK THE (D701) PARK ASSIST SENSOR 8 SIGNAL CIRCUIT FOR AN OPEN
1. Disconnect the Park Assist Module C2 harness connector.
2. Measure the resistance of the (D701) Park Assist Sensor 8 Signal circuit between the Park Assist Module C2 harness connector and the Park Assist Sensor harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Repair the (D701) Park Assist Sensor 8 Signal circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 8
PARK ASSIST SENSOR
1. Turn the ignition on.
2. Reconnect the Park Assist Module C2 harness connector.
3. Connect a jumper wire between the (X700) Park Assist Sensor Supply and (D701) Park Assist Sensor 8 Signal circuit at the Park Assist Sensor harness connector.
4. Turn the ignition on.
5. With the scan tool, read PAM DTCs.
