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 No. 1/2 and the wheel speed sensor body as a single unit.
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.
