NO

>> Repair or replace malfunctioning parts.

7.

DETECT MALFUNCTIONING ITEMS

Check the following items:

• Open circuit or short circuit in harness between ignition switch and IPDM E/R. Refer to 

PG-17, "Wiring Dia-

gram — Ignition Power Supply —"

.

• Short circuit in harness between IPDM E/R harness connector terminal 21 and output speed sensor harness

connector terminal 3.

• 10A fuse (No.49, IPDM E/R). Refer to 

PG-60, "IPDM E/R Terminal Arrangement"

.

• IPDM E/R
Is the check result normal?

YES

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.

DTC CONFIRMATION PROCEDURE

CAUTION:

Be careful of the driving speed.

1.

PREPARATION BEFORE OPERATION (PART 1)

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.

PREPARATION BEFORE OPERATION (PART 2)

With CONSULT

1. Start the engine.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Select “FLUID TEMP”.

4. Confirm that the CVT fluid temperature is in the following range. 

With GST

1. Start the engine.

2. Set the CVT fluid to 10

°C (50°F) or more. 

NOTE:

When the ambient temperature is 20

°C (68°F), the CVT fluid usually increases to 50 to 80°C (122 to

176

°F) with driving in an urban area for approximately 10 minutes. 

Is the CVT fluid 10

°C (50°F) or more? 

YES

>> GO TO 3.

NO

>> 1. Warm the transaxle. 

2. GO TO 3.

3.

CHECK DTC DETECTION

1. Drive the vehicle.

2. Maintain the following conditions for 10 seconds or more.

3. Stop the vehicle.

4. Check the first trip DTC.
Is “P0740” detected?

YES

>> Go to 

TM-166, "Diagnosis Procedure"

.

NO

Diagnosis Procedure

INFOID:0000000009019694

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 CVT unit harness connector terminal.

Is the inspection result normal?

YES 

>> GO TO 2.

NO

>> Repair or replace malfunctioning parts.

2.

CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE

Check torque converter clutch solenoid valve. Refer to 

TM-166, "Component Inspection (Torque Converter

Clutch 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 (Torque Converter Clutch Solenoid Valve)

INFOID:0000000009019695

1.
