Is the inspection result normal?

GO TO 3.

Replace terminal cord assembly. Refer to Removal and Installation.

CHECK CVT FLUID TEMPERATURE SENSOR

Check resistance between CVT unit connector terminals.

Is the inspection result normal?

Check intermittent incident. Refer to Intermittent Incident.

Replace terminal cord assembly. Refer to Removal and Installation.
