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

1. Start the engine.

2. Shift the selector lever to “D” position and wait for 5 seconds or more.

3. Check the first trip DTC.
Is “P0998” detected?

YES

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009268204

1.

CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

1. Turn ignition switch OFF.

2. Disconnect TCM connector and CVT unit connector.

3. 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 LOW BRAKE SOLENOID VALVE

Check low brake solenoid valve. Refer to

TM-391, "Component Inspection (Low Brake Solenoid Valve)"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to

GI-45, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.
