Self-diagnostic Function

Malfunction detection function

Memory function

  • The memory function detects a malfunction, changes it to a DTC, and stores it in the memory.

  • Once a DTC is stored, it can only be cleared by the designated procedure; not by turning the ignition switch to the LOCK position or disconnecting the negative battery cable. The procedure is mentioned in the workshop manual.

Display function

  • When the on-board diagnostic function has started, DTCs stored by the memory function are output to the DLC-2.
