Test D: Mirror Operates In One Second Intervals

NOTE: Many test steps refer to various connectors. To identify connectors, use illustrations. See Figure -Figure .
  1. Ensure transmission is in Park. Operate both mirrors in all directions. If both mirrors move in all directions, go to next step. If either mirror does not operate in any direction, repair as necessary. See SYMPTOM CHART under SELF-DIAGNOSTIC SYSTEM.
  2. Connect New Generation Star (NGS) tester to data link connector. Perform Driver Door Module (DDM) self-test. If no DDM DTCs exist, go to next step. If any DDM DTCs exists, perform appropriate test. See DIAGNOSTIC TROUBLE CODES (DDM) table under SELF-DIAGNOSTIC SYSTEM.
  3. Perform Driver Seat Module (DSM) self-test. If no DSM DTCs exist, go to next step. If any DSM DTCs exist, perform appropriate test or appropriate step. See DTC TEST PROCEDURE table.

  4. Ensure transmission is in Park. Position driver and passenger mirrors in center position. Operate both mirrors through complete travel in all directions. If both mirror move smoothly and completely, replace DSM. If driver mirror does not operate properly, go to next step. If passenger mirror does not operate properly, go to step 8). If both mirrors do not operate properly, go to step 11).
  5. Disconnect driver mirror harness connector C523. Disconnect DSM harness connector C313. Measure resistance between ground and terminals No. 4 (Red/White wire) and No. 1 (Dark Blue/White wire) at driver mirror harness connector C523. If both resistance readings are more than 10 k/ohms, go to next step. If either resistance reading is 10 k/ohms or less, repair short to ground in appropriate wire.
  6. Measure resistance in wires between DSM harness connector C313 and driver mirror harness connector C523. See DRIVER POTENTIOMETER CIRCUIT IDENTIFICATION table. If all resistance readings are 5 ohms or less, go to next step. If any resistance reading is more than 5 ohms, repair open in appropriate wire.
    DRIVER POTENTIOMETER CIRCUIT IDENTIFICATION

    DSM Terminal No. Mirror Terminal No. Wire Color
    9 4 Red/White
    10 1 Dark Blue/White
    13 3 Gray
    15 2 Gray/Red
  7. Measure voltage at terminal No. 1 (Dark Blue/White wire), No. 2 (Gray/Red wire), No. 3 (Gray wire) and No. 4 (Red/White wire) at driver mirror harness connector C523. If voltage does not exist at any terminal, go to step 14). If voltage exists at any terminal, repair short to voltage in appropriate wire.
  8. Disconnect passenger mirror harness connector C615. Disconnect DSM harness connector C313. Measure resistance between ground and terminals No. 1 (Purple/White wire) and No. 4 (Dark Green/White wire) at passenger mirror harness connector C615. If both resistance readings are more than 10 k/ohms, go to next step. If either resistance reading is 10 k/ohms or less, repair short to ground in appropriate wire.
  9. Measure resistance in wires between DSM harness connector C313 and passenger mirror harness connector C615. See PASSENGER POTENTIOMETER CIRCUIT IDENTIFICATION table. If all resistance readings are 5 ohms or less, go to next step. If any resistance reading is more than 5 ohms, repair open in appropriate wire.
    PASSENGER POTENTIOMETER CIRCUIT IDENTIFICATION

    DSM Terminal No. Mirror Terminal No. Wire Color
    11 4 Dark Green/White
    12 1 Purple/White
    13 3 Gray
    15 2 Gray/Red
  10. Measure voltage at terminal No. 1 (Purple/White wire), No. 2 (Gray/Red wire), No. 3 (Gray wire) and No. 4 (Dark Green/White wire) at passenger mirror harness connector C615. If voltage does not exist at any terminal, go to step 16). If voltage exists at any terminal, repair short to voltage in appropriate wire.
  11. Disconnect DSM harness connector C313, driver mirror harness connector C523 and passenger mirror harness connector C615. Measure resistance in Gary/Red wire between terminal No. 15 at DSM and terminal No. 2 at both mirror harness connectors. Also measure resistance in Gray wire between terminal No. 13 at DSM harness connector C313 and terminal No. 3 at both mirror harness connectors. If all resistance readings are 5 ohms or less, go to next step. If any resistance reading is more than 5 ohms, repair open in appropriate wire.
  12. Measure resistance between ground and terminal No. 2 (Gray/Red wire) at both mirror harness connectors. If resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Gray/Red wire.
  13. Measure voltage at terminal No. 2 (Gray/Red wire) at both mirror harness connectors. If voltage does not exist, go to step 18). If voltage exists, repair short to voltage in Gray/Red wire.
  14. Connect DSM harness connector C313. Measure voltage at terminals No. 1 (Dark Blue/White wire), No. 2 (Gray/Red wire) and No. 4 (Red/White wire) at driver mirror harness connector C523. If voltage exists, go to next step. If voltage does not exist, replace DSM.
  15. Measure resistance between ground and terminal No. 3 (Gray wire) at driver mirror harness connector C523. If resistance is more than 10 k/ohms, replace DSM. If resistance is 10 k/ohms or less, go to step 20).
  16. Connect DSM harness connector C313. Measure voltage at terminals No. 1 (Purple/White wire), No. 2 (Gray/Red wire) and No. 4 (Dark Green/White wire) at passenger mirror harness connector C615. If voltage exists, go to next step. If voltage does not exist, replace DSM.
  17. Measure resistance between ground and terminal No. 3 (Gray wire) at passenger mirror harness connector C615. If resistance is more than 10 k/ohms, replace DSM. If resistance is 10 k/ohms or less, go to step 21).
  18. Disconnect driver mirror harness connector C523 and passenger mirror harness connector C615. Measure voltage at terminal No. 2 (Gray/Red wire) at driver and passenger mirror harness connectors. If voltage does not exist, go to next step. If voltage exists at driver mirror harness connector, go to step 20). If voltage exists at passenger mirror, go to step 21).
  19. Measure resistance between ground and terminal No. 2 (Gray/Red wire) at driver and passenger mirror harness connectors. If both resistance reading are more than 10 k/ohms, go to step 22). If resistance is 10 k/ohms or less at driver mirror harness connector, go to next step. If resistance is 10 k/ohms or less at passenger mirror harness connector, go to step 21).
  20. Remove driver mirror assembly. Inspect mirror wiring. If wiring is damaged, repair as necessary. If wiring is okay, replace driver mirror assembly.
  21. Remove passenger mirror assembly. Inspect mirror wiring. If wiring is damaged, repair as necessary. If wiring is okay, replace passenger mirror assembly.
  22. Connect all disconnected components. Perform DSM self-test. If DTCs B1663, B1664, B1665 and B1666 do not exist, replace DSM. If DTCs B1663, B1664, B1665 and B1666 exist, preform appropriate test. See POWER SEATS article.
