WHEEL SPEED SENSOR OUTPUT VOLTAGE
CHECK
1. Lift up the vehicle and release the parking brake.
2. Disconnect the ABS-ECU connector, and then use the
special tool (inspection harness for connector pin contact
pressure) to measure the output voltage at the
harness-side connector.
3. Rotate the wheel to be measured at approximately 1/2 - 1
rotation per second, and check the output voltage using
a circuit tester or an oscilloscope.

Output voltage
When measuring with a circuit tester:
42 mV or more
When measuring with an oscilloscope:
120 mV p-p or more
4. If the output voltage is lower than the above values, the
reason could be as follow:
D
Faulty wheel speed sensor.
So replace the wheel speed sensor.
