DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V when engine is running.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is DTC detected? YES >> Proceed to EC-425, "Diagnosis Procedure".
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
Check the throttle control motor. Refer to EC-429, "Component Inspection (Throttle Control Motor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace electric throttle control actuator. Refer to EM-27, "Removal and Installation".
Component Inspection (Throttle Control Motor)
1.CHECK THROTTLE CONTROL MOTOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace electric throttle control actuator. Refer to EM-27, "Removal and Installation".
Environmental factors influence the rate of corrosion
Moisture
Accumulation of sand, dirt and water on the vehicle
body underside can accelerate corrosion.
Wet floor coverings will not dry completely inside
the vehicle and should be removed for drying to
avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of h ...
Abs branch line circuit
Diagnosis procedure
1.CHECK CONNECTOR
Turn the ignition switch OFF.
Disconnect the battery cable from the negative terminal.
Check the terminals and connectors of the ABS actuator and electric unit
(control unit) for damage, bend
and loose connection (unit side and connector side).
