DTC CONFIRMATION PROCEDURE

1.PREPARATION BEFORE WORK

If another вЂњDTC CONFIRMATION PROCEDUREвЂќ occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION

Start the engine and wait for 5 seconds or more
Check the first trip DTC.

Is вЂњP099CвЂќ detected? YES >> Go to TM-216, "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 CVT unit harness connector terminal.

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-216, "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".
