NO >> INSPECTION END
Diagnosis Procedure
1.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL
Check the voltage between ECM harness connector terminals as per the following conditions.
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 2.
2.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace error-detected parts.
3.CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY
Is the inspection result normal? YES >> GO TO 6.
NO >> Remove the foreign matter and clean the electric throttle control actuator inside, then perform throttle valve closed position learning. Refer to EC-139, "Work Procedure".
6.CHECK THROTTLE CONTROL MOTOR
