STEERING LOCK SYSTEM DTC CHECK / CLEAR

Note


  • The steering lock ECU does not store past DTCs. If any DTCs are output, confirm and record them as soon as possible. Do not turn the power switch off or clear the DTCs until the DTCs are confirmed and recorded.

  • DTCs may have been stored due to problems unrelated to the steering lock system. Be sure to confirm and record any DTCs output for other systems.

  • When using the GTS with the power switch off to troubleshoot:

    Connect the GTS to the DLC3 and turn a courtesy light switch on and off at 1.5 second intervals until communication between the GTS and vehicle begins.
