Wheel Speed Sensor Inspection




INSPECTION

WHEEL SPEED SENSOR CURRENT CHECK





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.
NOTE:
When measuring at the front wheel speed sensor

- Do not remove the front wheel speed sensor from the knuckle.
When measuring at the rear wheel speed sensor

- Do not remove the rear wheel speed sensor from the knuckle.

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.

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 terminal No. 1/2 and the wheel speed sensor body as a single unit.
Standard value: 5 Mohms or more
 2. If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
