3. Turn over floor carpet.
4. Hoist vehicle.
5. Disconnect connector of wheel speed sensor.
6. Connect voltmeter between connector (1) terminals.
7. While turning wheel at a speed of approximately 1/2 to 1 rotation per second, check AC voltage of sensor.
8. If measured voltage is not as specified, check sensor, ring and their installation conditions.
Reference
When using oscilloscope for this check, check if peak-to-peak voltage (1) meets specification and waveform is complete.
Peak-to-peak voltage at 1/2 to 1 rotation per second 150 mV or more at 21 - 42 Hz
