Wheel Speed Sensor Insulation Check

Remove the wheel speed sensor. Then, connect the circuit tester to the wheel speed sensor using the extra fine probe (special tool: MB992006), and measure the insulation resistance between the terminal No. 1/2 and the wheel speed sensor body.
Standard value: 5 MΩ or more
If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
