NOTICE

If the pulley bolt is tightened without holding, the actuator damage will occur.

This position is original position of the pulley.

NOTE

Correct the position electrically after confirming the use is discontinued and there is no damage when differing from the angle of shown in the figure.

NOTICE

Do not correct the pulley position with the tool, forcibly. The actuator damage will occur.

If the pulley angle is wrong, adjust the angle as follows.

Connect: 2 pins Connector 3 pins Connector

Turn the ignition switch to ON.

Confirm the pulley turns clockwise or counterclockwise then it stops at the original position.

Make sure that the pulley turns clockwise and then counterclockwise.

The pulley should returns to the original position.

Turn the ignition switch OFF.

If the pulley does not return to the original position, check the exhaust butterfly valve actuator resistance (see Exhaust Butterfly Valve Actuator Resistance Inspection).
