1.
| caution |
Do not connect the battery terminals in reverse as the wheel
speed sensor may be damaged.
|
Connect the circuit tester to the wheel speed sensor using the special tool extra fine
probe (MB992006), and measure the sensor current as a single unit.
Standard value: 5.9 to 8.4 mA or 11.8 to 16.8 mA
2.If the measurement value is not within the standard value range, replace the wheel
speed sensor with a new one.

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.
