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 and wait for 5 seconds or more.

2. Check the DTC.
Is “P0890” detected?

YES

>> Go to 

TM-180, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009019714

1.

CHECK TCM POWER SUPPLY (BACK-UP) CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect TCM connector.

3. Check voltage between TCM harness connector terminals and ground.

Is the inspection result normal?

YES 

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-41, "Intermittent Incident"

.

Is the inspection result normal?

YES 

>> Replace TCM. Refer to 

TM-237, "Removal and Installation"

.

NO

>> Repair or replace malfunctioning parts.

3.

DETECT MALFUNCTIONING ITEMS

Check the following items:

• Open circuit or short circuit in harness between battery positive terminal and TCM connectors terminals 45,

and 46.

• 10A fuse (No.25, fuse and fusible link block). Refer to 

PG-59, "Terminal Arrangement"

.

Is the inspection result normal?

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 and wait for 5 seconds or more.

2. Check the first trip DTC.
Is “P0962” detected?

YES

>> Go to 

TM-182, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009019716

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 LINE PRESSURE SOLENOID VALVE

Check line pressure solenoid valve. Refer to 

TM-182, "Component Inspection (Line Pressure Solenoid

Valve)"

.

Is the inspection result normal?

YES >> Check 

intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.

Component Inspection (Line Pressure Solenoid Valve)

INFOID:0000000009019717
