After tightening the pulley bolt, confirm whether pulley [A]
is an angle shown in the figure.
41.7° ±7° [B]
○
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 ON.
○
Confirm the pulley turns clockwise or counterclockwise
then it stops at the original position.
If the pulley position has not been returned to the original

2 pins connector terminals. To turn the pulley gradually,
intermittently connect the battery positive (+) terminal to
the 2 pin connector terminal while connecting the battery
negative (–) terminal to the connector.
Pink (–) lead terminal [A]
Gray (+) lead terminal [B]
Clockwise:
Pink (–) lead terminal to battery (–) terminal
Gray (+) lead terminal to battery (+) terminal
