Diagnostic Test

  1. READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR THE DTC TO RETURN 
    1. Turn the ignition on.
    2. With the scan tool, read DTCs in Driver Door Module (DDM) and record on the repair order.
    3. Open and close the driver door several times from the outside and inside handles.
    4. Wait 30 seconds.
    5. With the scan tool, read DDM DTCs.

      Is the DTC active?

      Yes 

      • Go To  2

      No 

  2. ISOLATE AND CHECK THE (P711) LEFT BLIND SPOT INDICATOR DRIVER CIRCUIT FOR A SHORT TO GROUND 
    1. The ignition must be off when checking a circuit for continuity to ground.
    2. Isolate the circuit by disconnecting the Driver Door Module (DDM) and every component harness connector containing the circuit being tested. Note:  Use the wiring diagram as a guide to follow the path of the circuit.
    3. Connect the negative lead of the DVOM to a known good ground.
    4. With the positive lead of the DVOM, probe the circuit being tested at the component harness connector and check for continuity between the circuit and ground.
      NOTE:

      There should be no continuity between ground and the circuit being tested.

      Is there continuity between ground and the circuit being tested?

      Yes 

      • Repair the circuit for a short to ground. Use the wiring diagram as a guide to trace the circuit and look for any in-line connectors to help isolate the location of the short.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

      No 

      • Go To  3
  3. ISOLATE AND CHECK THE (P711) LEFT BLIND SPOT INDICATOR DRIVER CIRCUIT FOR A SHORT TO ANOTHER CIRCUIT AT THE DDM HARNESS CONNECTOR 
    1. The ignition must be off when performing a resistance check to find a short between circuits.
    2. Isolate the circuit by disconnecting the Driver Door Module (DDM) and every component harness connector containing the circuit being tested. At this time leave all in-line connectors connected. Note:  Use the wiring diagram as a guide to follow the path of the circuit.
    3. Connect one lead of the DVOM to the circuit being tested at the DDM harness connector.
    4. With the other lead of the DVOM probe all other circuits at the DDM harness connector.
      NOTE:

      With the circuit isolated there should be no continuity between the circuit being tested and any other circuit.

      Is there continuity between the circuit being tested and any other circuit?

      Yes 

      • Repair the short between the circuits that have continuity. Use the wiring diagram as a guide to trace the circuits and look for any in-line connectors to help isolate the location of the short.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

      No 

      • Go To  4
  4. REPLACE THE MIRROR ASSEMBLY AND RETEST FOR DTCS 
    1. Turn the ignition off.
    2. Replace the Driver Outside Rearview Mirror in accordance with Service Information.Refer to OUTSIDE REARVIEW MIRROR, REMOVAL .
    3. Connect the component and Driver Door Module (DDM) harness connectors.
    4. Turn the ignition on.
    5. With the scan tool, erase all DTCs.
    6. Turn the ignition off for a minimum of 10.0 seconds.
    7. Turn the ignition on.
    8. Using the When Monitored and Set Conditions above and recorded data, operate the vehicle in the conditions that set the DTC.
    9. Open and close the door several times.
    10. With the scan tool, read DTCs.

      Did the DTC return?

      Yes 

      • Go To  5

      No 

  5. CHECK RELATED HARNESS CONNECTIONS 
    1. Disconnect all Driver Door Module harness connectors.
    2. Disconnect all related in-line harness connections (if equipped).
    3. Disconnect the related component harness connectors.
    4. 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.

    5. Reconnect all Driver Door Module harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
    6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
    7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
    8. With the scan tool, erase DTCs.
    9. Using the recorded Vehicle Scan Report, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
    10. With the scan tool, read DDM DTCs.

      Did the DTC return?

      Yes 

      No
