Symptom table

The probable malfunctioning circuit and parts corresponding to each malfunction phenomenon are shown below. This table is used for performing troubleshooting when a malfunction is still present although normal codes are displayed during DTC checking. The probable malfunction location indicates the inspection items of circuits and parts that must be checked.

NOTE: If a malfunction is not detected by the diagnostic system although malfunction symptoms are present, it is thought that the malfunction has occurred in a location outside of the detection scope of the diagnostic system, or in a system other than the diagnostic system.
