On-Board Diagnostics

If the ASC-ECU detects any problem in the CAN communication line or the ECUs, which the ASC-ECU is communicating with, it sets a DTC. The DTCs can be confirmed by connecting scan tool (M.U.T.-III). The set DTCs are not erased even after the ignition switch has been turned to the "LOCK" (OFF) position, or the battery has been disconnected. The DTCs can be erased by operating scan tool (M.U.T.-III).
