Wheel Speed Sensor Insulation Check
- 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 number 1 or 2 and the wheel speed sensor body as a single unit.
Standard value: 1.5 MΩ or more
- If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
