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 10 seconds or more.

Selector lever : D position Vehicle speed : 55 km/h (34 MPH) or more

4. Stop the vehicle.

5. Check the first trip DTC.

Is P0720 detected? YES >> Go to TM-413, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK OUTPUT SPEED SENSOR POWER CIRCUIT

Check the voltage between the output speed sensor harness connector terminal and ground.

Is the check result normal?


Is the check result normal? YES >> GO TO 6.

NO >> GO TO 2.

2.CHECK OUTPUT SPEED SENSOR GROUND CIRCUIT

Check the continuity between the output speed sensor harness connector terminal and ground.

Is the check result normal?


Is the check result normal? YES >> GO TO 3.

NO >> Repair or replace the malfunctioning parts.

3.CHECK CIRCUIT BETWEEN OUTPUT SPEED SENSOR AND TCM (PART 1)

1. Turn ignition switch OFF.

2. Disconnect the TCM connector.

3. Check the continuity between the output speed sensor harness connector terminal and the TCM harness connector terminal.

Is the check result normal?


Is the check result normal? YES >> GO TO 4.

NO >> Repair or replace the malfunctioning parts.

4.CHECK CIRCUIT BETWEEN OUTPUT SPEED SENSOR AND TCM (PART 1)

Check the continuity between the output speed sensor harness connector terminal and ground.

Is the check result normal?


Is the check result normal? YES >> GO TO 5.

NO >> Repair or replace the malfunctioning parts.

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 output speed sensor.

Is the check result normal?


Is the check result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO >> Replace the output speed sensor. Refer to TM-497, "Exploded View".

6.CHECK CIRCUIT BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR (PART 1)

1. Disconnect the IPDM E/R connector.

2. Check the continuity between the IPDM E/R harness connector terminal and the output speed sensor harness connector terminal.

Is the check result normal?


Is the check result normal? YES >> GO TO 7.

NO >> Repair or replace the malfunctioning parts.

7.CHECK CIRCUIT BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR (PART 2)

Check the continuity between the IPDM E/R vehicle-side harness connector terminal and ground.

Is the check result normal?


Is the check result normal? YES >> GO TO 8.

NO >> Repair or replace the malfunctioning parts.

8.DETECTION OF MALFUNCTION ITEMS

Check the following items: Harness open circuit or short circuit between the ignition switch and IPDM E/R. Refer to PG-15, "Wiring Diagram - IGNITION POWER SUPPLY -".

10A fuse (No.55, IPDM E/R). Refer to PG-25, "Fuse, Connector and Terminal Arrangement".

IPDM E/R

Is the check result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO >> Repair or replace the malfunctioning parts.
