1.
| caution |
Do not connect the auxiliary battery terminals in reverse as the wheel
speed sensor may be damaged.
|
Remove the wheel speed sensor. Then, connect the circuit tester to the
wheel speed sensor using the extra fine probe (special tool: MB992006), and measure the sensor
current.
Standard value:
Low: 5.9 - 8.4 mA
High: 11.8 - 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.Remove the wheel speed sensor. Then, 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.
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.
