Diagnostic Procedure

WARNING: This page is about a different car, the 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If not using the hand-held tester, start the inspection from step  2.
  1. Check the illumination (interior light and ignition switch light) using the hand-held tester. Connect the hand-held tester to the DLC3. See Figure. Check that the illumination can light in an ACTIVE TEST. If all the illumination lights, perform the next test procedure of the problem symptom. See step  4 of the SYSTEM OPERATION CHECK under TROUBLE SHOOTING. If all the illumination does not light, go to the next step.
  2. Check the illumination light. If the results are OK, go to the next step. If the results are not good, replace the failure light.
  3. Check the wiring harness and connector between each illumination light and body ECU, battery and each illumination light. If the results are OK, perform the next test procedure of the problem symptom. See step  4 of the SYSTEM OPERATION CHECK under TROUBLE SHOOTING. If the results are not good, repair or replace the wiring harness or connector.
