Wheel Speed Sensor Insulation Check
Fig 1: Measuring Insulation Resistance Between Terminal No. 1/2 And Wheel Speed Sensor Body As Single Unit
- Connect the circuit tester to the wheel speed sensor using the special tool extra fine probe (MB992006), and measure the insulation resistance between terminal No. 1/2 and the wheel speed sensor body as a single unit.
Standard value: 5 M Ω or more
- If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
