  1. Close and lock all doors. Measure voltage at specified terminals of CPU 20-pin connector and take appropriate action. See DOOR LOCK LINK SWITCHES CIRCUIT TEST table. SeeFigure .
    DOOR LOCK LINK SWITCHES CIRCUIT TEST

    Terminal (Wire Color) Voltage Reading Action
    2H (Light Green) About 5 Check Next Terminal (2F)
    2H (Light Green) Except 5 Go To Step 2)
    1992
    2F (Light Green) About 5 Check Next Terminal (2J)
    2F (Light Green) Except 5 Go To Step 4)
    1993
    2F (Green/Orange) About 5 Check Next Terminal (2J)
    2F (Green/Orange) Except 5 Go To Step 4)
    2J (Green/Black) About 5 Replace CPU
    2J (Green/Black) Except 5 Go To Step 6)
  2. Disconnect CPU 20-pin connector. Check continuity between ground and terminal 2H (Light Green wire) (2H (Green/Orange wire on 1992 models)) of CPU 20-pin connector. If there is continuity, go to step 6). If there is no continuity, replace CPU.
  3. Check driver door lock link switch. See DOOR LOCK LINK SWITCH under COMPONENT TESTING  . If switch is faulty, replace door lock actuator. If switch is okay, repair wiring between CPU and switch.
  4. Disconnect CPU 20-pin connector. Check continuity between ground and terminal 2F (Green/Orange wire) of CPU 20-pin connector. If there is no continuity, replace CPU. If there is continuity, go to next step.
  5. Check passenger door lock link switch. See DOOR LOCK LINK SWITCH under COMPONENT TESTING  . If switch is faulty, replace door lock actuator. If switch is okay, repair wiring between CPU and switch.
  6. Disconnect CPU 20-pin connector. Check continuity between ground and terminal 2J (Green/Black wire) of CPU 20-pin connector. If there is no continuity, replace CPU. If there is continuity, go to next step.
  7. Check rear door lock link switches. See DOOR LOCK LINK SWITCH under COMPONENT TESTING  . If switch is faulty, replace door lock actuator. If switch is okay, repair wiring between CPU and switch.
