INSPECTION CHART FOR DIAGNOSIS CODE

---

warning

When touching the throttle valve, surely shut off the driving circuits of the throttle valve. In the event that the throttle valve is operated, a finger might be injured as the result of being caught by the throttle valve.

caution

When the ignition switch is turned ON with the connector disconnected in proceeding with troubleshooting, the diagnosis code may be stored in other systems. Erase codes if diagnosis codes of all the systems are checked and the codes are output after completion of the troubleshooting.
