  1. Remove lower panel from instrument panel. Disconnect 8-pin connector from main wiring harness and note terminal identification. See Fig 1 .
  2. Using an ohmmeter, check for continuity between the designated terminals with the ignition lock assembly in the ACC position in relation to installation of the ignition key. Refer to the KEY INTERLOCK SOLENOID CONTINUITY SPECIFICATIONS  table.
  3. Replace ignition lock assembly if continuity is not as specified, as key interlock solenoid cannot be serviced separately.
