2.

Check the electric throttle control actuator harness connector connection.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace error-detected parts.

3.

CHECK ELECTRIC THROTTLE CONTROL ACTUATOR CIRCUIT

Check the electric throttle control actuator circuit for open and short.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK THROTTLE CONTROL MOTOR

Perform 

EC-1177, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace electric throttle control actuator.
