Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related service information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
INSPECT COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to OFF.
•  Disconnect the coupler component connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 9.
No
Go to the next step.
3
INSPECT TCC SOLENOID, TCC ENGAGE SOLENOID AND BELT GRIP PRESSURE LINEAR SOLENOID CIRCUIT FOR SHORT TO GND
•  Switch the ignition to OFF.
•  Inspect for continuity between the following circuits:
―  Coupler component terminal J (wiring harness-side) and body GND
―  Coupler component terminal I (wiring harness-side) and body GND
―  Coupler component terminal E (wiring harness-side) and body GND
―  Coupler component terminal F (wiring harness-side) and body GND
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to GND, then go to Step 9.
No
Go to the next step.
4
INSPECT TCC SOLENOID, TCC ENGAGE SOLENOID AND BELT GRIP PRESSURE LINEAR SOLENOID CIRCUIT FOR SHORT TO POWER SUPPLY
•  Switch the ignition to ON (Engine off).
•  Measure the voltage between the following circuits:
―  Coupler component terminal J (wiring harness-side) and body GND
―  Coupler component terminal I (wiring harness-side) and body GND
―  Coupler component terminal E (wiring harness-side) and body GND
―  Coupler component terminal F (wiring harness-side) and body GND
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
No
Go to the next step.
5
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to OFF.
•  Disconnect the TCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to the Step 9.
No
Go to the next step.
6
INSPECT TCC SOLENOID, TCC ENGAGE SOLENOID AND BELT GRIP PRESSURE LINEAR SOLENOID CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to OFF.
•  Inspect for continuity between the following circuits:
―  Coupler component terminal J (wiring harness-side) and TCM terminal A16
―  Coupler component terminal I (wiring harness-side) and TCM terminal A5
―  Coupler component terminal E (wiring harness-side) and TCM terminal A4
―  Coupler component terminal F (wiring harness-side) and TCM terminal A2
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the Step 9.
7
INSPECT SOLENOID VALVE
•  Inspect the following solenoid valve.
―  TCC solenoid
―  TCC engage solenoid
―  Belt grip pressure linear solenoid
•  Is there any malfunction?
Yes
Perform the following procedure, then go to Step 9.
1.  Replace the CVT.
2.  Perform oil pressure sensor learning.
No
Go to the next step.
8
INSPECT CVT
•  Perform the “Mechanical System Test”.
•  Perform the “Road Test”.
•  Is there any malfunction?
Yes
Perform the following procedure, then go to next step.
1.  Replace the CVT.
2.  Perform oil pressure sensor learning.
No
Go to the next step.
9
VERIFY TROUBLESHOOTING OF DTC P0741:00 COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC using the M-MDS.
•  Perform the following procedure to ensure that the DTC has been resolved:
1.  Start the engine.
2.  Vehicle stopped after being driven in D range.
•  Is the same DTC present?
Yes
Perform the following procedure, then go to next step.
1.  Replace the TCM.
2.  Perform TCM learning.
No
Go to the next step.
10
