Wheel Speed Sensor Current Check
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
- If the measurement value is not within the standard value range, replace the wheel speed sensor with a new one.
