Actuator Assembly Test

1 . Disconnect the 4-P connector from the actuator. 2. Check the output linkage for smooth movement.

3. Connect battery power to the D terminal and ground to the A terminal.

4. Check for a clicking sound from the magnetic clutch. The output linkage should be locked. You should be able to hear the motor.

5. If the output linkage is not locked, replace the actuator assembly.

6. Check the operation of the actuator motor in each output linkage position according to the table. You should be able to hear the motor.

Actuator Cable Adjustment

1 . Check that the actuator cable operates smoothly with no binding or sticking.

2. Start the engine and warm it up to normal operating
temperature (the cooling fans come on twice).

3. Measure the amount of movement of the output linkage until the engine speed starts to increase. At first, the output linkage should be located at the fully closed position. Free play should be 1 1 ± 1. 5 mm (0.43 ± 0.06 in).

4. If the free play is not within specs, loosen the

NOTE: If necessary, check the throttle control system (see Section 11 ), then recheck the output linkage free play.

5. Retighten the locknut and recheck the free play.
