Ignition Switch & Circuit Test: Cressida

  1. Remove driver's lower instrument panel cover. Remove upper and lower steering column covers if needed. Locate ignition switch wiring harness connector (10-cavity connector).
  2. Using test light, backprobe White wire terminal of ignition switch wiring harness connector. If test light glows, go to next step. If test light does not glow, check for blown Black or White fusible link near battery or in fusible link box near battery. Also check large amperage fuses (ALT and AM1) in engine compartment fuse/relay block. If all are okay, check for open in White wire to ignition switch. Repair as required.
  3. Using test light, backprobe Black/White wire terminal of ignition switch wiring harness connector. Turn ignition switch to START position. If test light does not glow, replace ignition switch. If test light glows on Canada models, check Black/White wire circuit to neutral start switch for open or short. Repair as required. If test light glows on USA models, check Black/White wire circuit to starter relay for open or short. Repair as required.
