Disconnect TCM connector and CVT unit connector.
Check continuity between TCM harness connector terminal and CVT unit harness connector terminal.

Is the inspection result normal?

YES >> GO TO 2.

NO >> Repair or replace malfunctioning parts.

2.CHECK LOW BRAKE SOLENOID VALVE

Check low brake solenoid valve. Refer to TM "Component Inspection (Low Brake Solenoid Valve)".

Is the inspection result normal?

YES >> Check intermittent incident. Refer to GI "Intermittent Incident".

Component Inspection (Low Brake Solenoid Valve)

1.CHECK LOW BRAKE SOLENOID VALVE

Check resistance between CVT unit connector terminal and ground.

Is the inspection result normal?

YES >> INSPECTION END

NO >> There is a malfunction of low brake solenoid valve. Replace transaxle assembly. Refer to TM "Removal and Installation".
