P0730 BELT DAMAGE

P0730 BELT DAMAGE

Description

INFOID:0000000003806403

TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signals. Then it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.

DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.
NOTE:
If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch
OFF. Then wait at least 10 seconds before performing the next test.
Perform the following procedure to confirm the malfunction is eliminated after the repair.

1.

CHECK DTC DETECTION

With CONSULT-III

1.

Turn ignition switch ON.

2.

Select “Data Monitor” mode for “TRANSMISSION”.

3.

Make sure that output voltage of CVT fluid temperature sensor is within the range specified below.

4.

Start engine and maintain the following conditions for at least 30 consecutive seconds.

Is “P0730 BELT DAMG” detected?

YES

>> Go to 

TM-228, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-35, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000003806405

1.

CHECK DTC

With CONSULT-III

1.

Turn ignition switch ON.

2.

Select “Self Diagnostic Results” mode for “TRANSMISSION”.

Are any DTC displayed?

YES - 1 (DTC for “P0730 BELT DAMG” is displayed)>>Replace the transaxle assembly. Refer to 

TM-332,

"Exploded View"

.

YES - 2 (DTC except for “P0730 BELT DAMG” is displayed)>>Check the DTC detected item. Refer to 

TM-

204, "CONSULT-III Function (TRANSMISSION)"

.

If it is out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to increase the 
voltage (cool down the fluid)

Start test from 0 km/h (0 MPH)

Constant acceleration

: Keep 30 sec or more

VEHICLE SPEED

: 10 km/h (6 MPH) or more

ACC PEDAL OPEN

: More than 1.0/8

P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE

P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE

Description

INFOID:0000000003806406

• The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehi-

cle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.

• Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
• When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed shall not

change abruptly. If there is a big jump in engine speed, there is no lock-up.

Perform the following procedure to confirm the malfunction is eliminated after the repair.

1.

CHECK DTC DETECTION

With CONSULT-III

1.

Turn ignition switch ON.

2.

Wait at least 10 consecutive seconds.

3.

Check “Self Diagnostic Results” mode for “TRANSMISSION”.

With GST

Follow the procedure “With CONSULT-III”.

Is “P0740 TCC SOLENOID/CIRC” detected?

YES

>> Go to 

TM-230, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-35, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000003806408

1.

CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector.

3.

Check resistance between TCM vehicle side harness connector terminal and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 2.

2.

CHECK HARNESS BETWEEN TCM AND CVT UNIT (TORQUE CONVERTER CLUTCH SOLENOID

VALVE) (PART 1)

1.

Disconnect CVT unit connector.

2.

Check continuity between TCM vehicle side harness connector terminal and CVT unit vehicle side har-
ness connector terminal.
