WHEEL SPEED SENSOR INSULATION CHECK
1. Connect the circuit tester to the wheel speed sensor using the special tool extra fine probe (MB992006), and measure the insulation resistance between the terminal No. 1/2 and the wheel speed sensor body as a single unit.Standard value: 5 MΩ or more
2. If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
