P0730 BELT DAMAGE
DescriptionINFOID:0000000003848973
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:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
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 below.
4. Start engine and maintain the following conditions for at least 30 consecutive seconds.
Is
“P0730 BELT DAMG” detected?
YES >> Go to TM-60, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003848975
1.CHECK DTC
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.
Are any DTC detected?
YES-1 (DTC for “P0730 BELT DAMG” is detected)>>Replace transaxle assembly. Refer to TM-168,
"Exploded View".
YES-2 (DTC except for “P0730 BELT DAMG” is detected)>>Check DTC detected item. Refer to TM-37,
"CONSULT-III Function (TRANSMISSION)".
NO >> GO TO 2.
2.DETECT MALFUNCTIONING ITEMS
DTCItem
(CONSULT-III screen term)Malfunction is detected when... Possible cause
P0730 BELT DAMG Unexpected gear ratio detected. Transaxle assembly
ATF TEMP SEN : 1.0 – 2.0 V
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
RANGE : “D” position
ENG SPEED : 450 rpm or more

P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000003848976
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.

DTC CONFIRMATION PROCEDURE
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Wait at least 10 consecutive seconds.
3. Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.
With GST
Follow the procedure “With CONSULT-III”.
Is
“P0740 TCC SOLENOID/CIRC” detected?
YES >> Go to TM-62, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003848978
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
VA LV E ) ( PA R T 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.
