PG-52, "Wiring Dia-

gram - IGNITION POWER SUPPLY -"

.

• Short circuit in harness between IPDM E/R harness connector terminal 70 and input speed sensor harness

connector terminal 3.

• 10A fuse (No.93, located in the IPDM E/R). Refer to 

PG-89, "Fuse, Connector and Terminal Arrangement"

.

• IPDM E/R

P0740 TORQUE CONVERTER

DTC Description

INFOID:0000000010622526

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector (Torque converter clutch solenoid valve circuit is open or shorted to power supply)
• Torque converter clutch solenoid valve

FAIL-SAFE

• Start  is  slow
• Acceleration is slow
• Lock-up is not performed

DTC CONFIRMATION PROCEDURE

CAUTION:

Be careful of the driving speed.

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.

PREPARATION BEFORE OPERATION

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 20

°

C (68

°

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 20

°

C (68

°

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.
