  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 door latch (see FRONT DOOR LATCH REPLACEMENT )
