1.Disconnect the variable
resistor connector. 2.Use a circuit tester to
measure the resistance between terminal No. 1 and No. 3 of
the variable resistor connector. Standard
value: 3.5 - 6.5 kΩ

3.Connect the circuit tester
between the terminal No. 1 and No. 2. 4.Check that
the resistance changes smoothly when the adjusting screw is
rotated by
the special tool MAS screwdriver
(MD998299). 5.Inspect the body for crack or other
damage. 6.If any defect is found, replace the
variable resistor as an assembly.
