Voltage Inspection

Caution

• If the wiring harnesses or waterproof connectors are damaged, water penetrating the connector will cause a sensor malfunction. To prevent this, be careful not to damage wiring harnesses or waterproof connectors.

1.Lift up the vehicle.

2.Remove the front under cover No.2. (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

3.Measure the output voltage wave pattern between revolution sensor terminals A and B using an oscilloscope.

• If not as specified, replace the revolution sensor. (See REVOLUTION SENSOR REMOVAL/INSTALLATION [C66M-R].)
