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.CHECK DTC DETECTION

1. Start the engine.
2. Drive the vehicle.
3. Maintain the following conditions for 5 seconds or more.
4. Stop the vehicle.
5. Check the first trip DTC.

Engine speed : More than 1,500 rpm

Accelerator pedal position : 0.5/8.0 or more

Selector lever : D position

Vehicle speed : More than 40 km/h (25 MPH)

Is "P0717" detected?

YES >> Go to TM, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK INPUT SPEED SENSOR POWER CIRCUIT

1. Turn ignition switch OFF.
2. Disconnect the transaxle assembly connector.
3. Turn ignition switch ON.
4. Check the voltage between the A/T unit harness connector and ground. 

Is the check result normal?

YES >> GO TO 2.

NO >> Check the TCM power supply. Refer to TM, "Diagnosis Procedure".

2.CHECK INPUT SPEED SENSOR GROUND CIRCUIT

1. Turn ignition switch OFF.
2. Check the continuity between the A/T unit harness connector and ground.  

Is the check result normal?

YES >> GO TO 3.

NO >> Check or repair the malfunction items.

3.CHECK INPUT SPEED SENSOR SIGNAL CIRCUIT

1. Disconnect the TCM connector.
2. Check the continuity between the TCM harness connector and the A/T unit harness connector. 

Is the check result normal?

YES >> GO TO 4.

NO >> Check or repair the malfunction items.

4.CHECK INPUT SPEED SENSOR TCM CIRCUIT (CHECK 3)

Check the continuity between TCM harness connector and ground.  

Is the check result normal?

YES >> GO TO 5.

NO >> Check or repair the malfunction items.

5.CHECK TCM INPUT SIGNALS

1. Connect all of the disconnected connectors.
2. Lift the vehicle.
3. Start the engine.
4. Check the frequency of the input speed sensor. 

Is the check result normal?

YES >> Perform a simulation test to judge the cause of the malfunction. Refer to GI, "Intermittent Incident".

NO >> Replace the transaxle assembly. Refer to TM, "Removal and Installation".
