FUEL INJECTION SYSTEM
DIAGNOSTIC MODE
• In this mode, diagnostic codes are input into the ECU in accordance with the number of times the
start switch has been operated.
• In accordance with the diagnostic codes, the ECU displays the values received from the sensors
and actuates the actuators.
• Whether or not the system is operating normally is determined by a human operator through the
observations of the values indicated by the engine trouble warning light or the actuating condi-
tions of the actuators.
