DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” 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 “P099B” 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? 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? YES >> INSPECTION END
NO >> There is a malfunction of high & reverse brake solenoid valve. Replace transaxle assembly. Refer to TM-283, "Removal and Installation".
