Safety Indicator Input Test

1.Before testing the safery indicatar functions, troubleshoot the multiplex integrated control system test mode A.

Multiplex Integrated Control Unit


2.Remove the left kick panel (LHD type) or right kick panel (RHD type).

3.Disconnect the under-dash fuse/relay box connectors E, H and P.

NOTE: All connectors are wire side of female terminals.

4.Inspect the connector and socket terminals to be sure they are all making good contact.

  • If the terminals are bent, loose or corroded, repair them as necessary, are recheck the system.
  • If the terminals look OK, go to 5.

5.Reconnect the connectors to the under-dash fuse relay box, and make sure these input tests at the appropriate connectors on the under-dash fuse/relay box.

  • If any test indicates a problem, find and correct the cause, then recheck the system.
  • If all the input tests prove OK, go to 6.

6.Perform the gauge self diagnostic procedure.

  • Do the indicators flash, go to 7.
  • Do the indicators not flash, replace the gauge control module.

7.Substitute a known-good under-dash fuse/relay box and recheck the system.

  • If the symptom is gone, the MICU is faulty; replace the under-dash fuse/relay box.
  • If the symptom is still present, the gauge cotrol module must be faulty; replace the gauge control module.
