Check the first trip DTC.

Is вЂњP099BвЂќ detected? YES >> Go to TM-214, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

Turn ignition switch OFF.
Disconnect TCM connector and CVT unit connector.
Check continuity between TCM harness connector terminal and ground.

Is the inspection result normal?

Is the inspection result normal? YES >> GO TO 2.

NO >> Repair or replace malfunctioning parts.

2.CHECK HIGH CLUTCH & REVERSE BRAKE SOLENOID VALVE

Check high clutch & reverse brake solenoid valve. Refer to TM-214, "Component Inspection".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO >> Repair or replace malfunctioning parts.

Component Inspection

1.CHECK HIGH CLUTCH & REVERSE BRAKE SOLENOID VALVE

Check resistance between CVT unit connector terminal and ground.

Is the inspection result normal?

Is the inspection result normal? YES >> INSPECTION END

NO >> There is a malfunction of high & reverse brake solenoid valve. Replace transaxle assembly. Refer to TM-283, "Removal and Installation".
