Power Window Master Switch/Driver Door Lock Control Switch Circuit

  1. Remove door trim panel and service hole cover to access power window master switch/door lock control switch connector. Disconnect 10-pin power window master switch/door lock control switch connector. Turn ignition on. Using a voltmeter, measure voltage between body ground and switch connector terminals No. 1 (Green wire), No. 2 (Red/Black wire) and No. 8 (White/Black wire) with switch in specified position. See DRIVER DOOR LOCK CONTROL SWITCH VOLTAGE  table. If voltage is as specified, go to next step. If voltage is not as specified, replace door lock control switch.
    DRIVER DOOR LOCK CONTROL SWITCH VOLTAGE

    Switch Position Terminal No. & Ground Voltage
    Lock 2 Less Than One
    Lock 1 6-8
    Unlock 2 6-8
    Unlock 1 Less Than One
    Neutral 2 6-8
    Neutral 1 6-8
  2. Using an ohmmeter, check continuity between switch connector terminals No. 1 (Green wire), No. 2 (Red/Black wire) and No. 8 (White/Black wire) with switch in specified position. See DRIVER DOOR LOCK CONTROL SWITCH CONTINUITY  table. If continuity is as specified, go to next step. If continuity is not as specified, replace door lock control switch.
    DRIVER DOOR LOCK CONTROL SWITCH CONTINUITY

    Switch Position Terminals No. Continuity
    Lock 2 & 8 Yes
    Unlock 1 & 8 Yes
    Neutral 2 & 8; 1 & 8 No
  3. Check circuits for faults between power window master switch/door lock control switch, anti-theft/door lock control ECU and body ground. See WIRING DIAGRAMS . Repair or replace as necessary. If circuits are okay, check anti-theft/door lock control ECU pin voltages. See ANTI-THEFT/DOOR LOCK CONTROL ECU PIN VOLTAGE TESTS  under COMPONENT TESTS. Replace as necessary and retest system operation. Proceed to next test listed in appropriate SYMPTOM DIAGNOSIS table under TROUBLE SHOOTING .
