High/Low Beam Switching Solenoid Test

1. Remove the battery cover (left side) or right front fender trim (right side).




2. Disconnect the 3P connector (A) from the high/low switching solenoid connector (B).
3. Turn the solenoid connector 45 degrees counterclockwise, and pull it out slightly from the headlight housing.




4. Check the solenoid operation by connecting power to the No. 3 terminal and ground the No. 2 terminal momentarily. The solenoid should work.
