    • Yes  : GO to  C4.
    • No  : GO to C2.
  2. C2 VERIFY DIGITAL TRANSMISSION RANGE SENSOR ALIGNMENT 
    • Check to make sure the digital TR sensor harness connector is fully seated, pins are fully engaged in connector and in good condition before proceeding.
    • Apply the parking brake.
    • Select NEUTRAL.
    • Disconnect the shift cable/linkage from the manual lever.
    • Verify that the TR Sensor Alignment Gauge fits in the appropriate slots.
    • Is the digital TR sensor adjustment OK? 
    • Yes  : GO to C3.

    • Select DRIVE.
    • Reconnect the shift cable/linkage.
    • Verify that the shift cable/linkage is adjusted OK.
    • Is the shift cable/linkage adjusted OK? 
  4. C4 CHECK ELECTRICAL SIGNAL OPERATION 
    • Select PARK.
    • Disconnect: Digital TR Sensor.
      CAUTION: Do not pry on connector. This will damage the connector and result in a transmission concern.

      Press the button and pull out on the digital TR harness connector.

    • Inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals.
    • Are the connector, pins and harness damaged? 
    • Yes  : REPAIR as required. CLEAR DTCs and REPEAT OBD Tests.
    • No  : If diagnosing a DTC, GO to C5. If diagnosing a starting concern or a reversing lamp concern, GO to  C10.
  5. C5 CHECK ELECTRICAL SYSTEM OPERATION (DIGITAL TR AND PCM) 
    • Key in OFF position.
    • Connect the scan tool.
    • Connect: Digital TR Sensor.
    • Key in ON position.
    • Enter the following diagnostic mode on the scan tool: TR PIDS TR, TR___D, TR___V.
    • Move transmission range selector lever into each gear and stop.
    • Observe any of the following PIDs, TR and TR___D, TR___V (vehicle dependent) while wiggling harness, tapping on sensor or driving the vehicle. Use PIDs TR and TR___D for DTCs P0705, P1704 and P1705. Use PIDs TR and TR___V for DTC P0708. Compare the PIDs to the Digital Transmission Range (TR) Sensor Diagnosis Chart.
    • Do the PIDs TR, TR___D and TR___V match the Digital Transmission Range (TR) Sensor Diagnosis chart and does the TR___D PID remain steady when the harness is wiggled, the sensor is tapped or the vehicle driven? 
    • Yes  : The problem is not in the digital TR sensor system. REFER to DIAGNOSIS BY SYMPTOM  for further diagnosis.
    • No  : If TR___D changes when wiggling harness, tapping on the sensor or driving the vehicle, the problem may be intermittent. GO to C6.
  6. C6 CHECK DIGITAL TRANSMISSION RANGE SENSOR OPERATION 
    • Disconnect: Digital TR Sensor.
      CAUTION: Do not pry on the connector. This will damage the connector and result in a transmission concern.

    • Connect: TR-E Cable to Digital TR Sensor.
    • Place the Digital TR Overlay onto Transmission Tester.
    • Carry out Sensor Test as instructed on the Digital TR Overlay.
    • Does the status lamp on the tester TRS-E cable match the selected gear positions? 
    • Yes  : Concern is not in the digital TR sensor, GO to C7.
    • No  : INSTALL a new digital TR sensor. CLEAR DTCs and REPEAT OBD Tests.
  7. C7 CHECK THE PCM HARNESS CIRCUITS FOR OPENS 
    • Key in OFF position.
    • Disconnect: Powertrain Control Module (PCM).
    • Inspect for damaged or pushed-out pins, corrosion or loose wires.
    • Disconnect: Digital TR Sensor.
      CAUTION: Do not pry on the connector. This will damage the connector and result in a transmission concern.

      Disconnect the digital TR sensor connector.
