  3. Check for continuity between the terminals.
    • There should be continuity between terminals No. 9 and No. 5 when the door key cylinder switch is in LOCK position.
    • There should be no continuity between terminals No. 9 and No. 5 when the door key cylinder switch is in the neutral or UNLOCK position.
    • There should be continuity between terminals No. 8 and No. 5 when the door key cylinder switch is in UNLOCK position.
    • There should be no continuity between terminals No. 8 and No. 5 when the door key cylinder switch is in the neutral or LOCK position.
    • There should be no continuity between terminals No. 8 and No. 9 when the key is in the neutral position.
  4. If the continuity is not as specified, the switch is faulty; replace the driver's door latch (see FRONT DOOR LATCH REPLACEMENT ).
