Test D: Left Front Window Is Inoperative

  1. Check Switch Input  - Using NGS tester, select and monitor DDM PID D_PW_SW. Press and release driver door window control switch in the UP and DOWN position several times. If PID D_PW_SW values agree with the switch position, go to next step. If PID D_PW_SW values do not agree with the switch position, replace driver door module and retest system operation.
  2. Check Yellow/Light Green Wire For Open  - Turn ignition off. Disconnect DDM 4-pin connector C522 (located in lower front corner of driver door). Using a voltmeter, check voltage between ground and DDM 4-pin C522 connector terminal No. 3 (Yellow/Light Green wire). If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Yellow/Light Green wire and retest system operation.
  3. Check Black Wire For Open  - Using an ohmmeter, check resistance between ground and DDM 4-pin C522 connector terminal No. 4 (Black wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black wire and retest system operation.
  4. Check Left Front Window Output To Motor  - Reconnect DDM 4-pin connector C522. Disconnect left front window motor connector C514. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and left front window motor connector C514 (harness side) Red/Yellow wire while pressing left front window control switch to UP position. Check voltage between ground and left front window motor connector C514 (harness side) Pink/Yellow wire while pressing left front window control switch to DOWN position. If voltage does not cycle from zero volts to battery voltage when switches are pressed, go to next step. If voltage cycles from zero volts to battery voltage when switches are pressed, go to step 6).
  5. Check Pink/Yellow & Red/Yellow Wires For Open  - Turn ignition off. Disconnect DDM 4-pin connector C522 (located in lower front corner of driver door). Using an ohmmeter, check resistance in Pink/Yellow wire between DDM 4-pin C522 connector terminal No. 1 and left front window motor connector C514. Check resistance in Red/Yellow wire between DDM 4-pin C522 connector terminal No. 2 and left front window motor connector C514. If either resistance reading is 5 ohms or more, repair open in Pink/Yellow or Red/Yellow wire(s) and retest system operation. If both resistance readings are less than 5 ohms, replace driver door module and retest system operation.
  6. Check Pink/Yellow & Red/Yellow Wires For Short To Ground  - Using an ohmmeter, check resistance between ground and left front window motor connector C514 Pink/Yellow wire terminal. Check resistance between ground and left front window motor connector C514 Red/Yellow wire terminal. If either resistance reading is 10 k/ohms or less, replace left front window motor and retest system operation. If both resistance readings are more than 10 k/ohms, replace driver door module and retest system operation.
