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.

4. Stop the vehicle.

5. Check the first trip DTC.

OUTPUT SPEED SENSOR
(Output Speed Sensor Circuit)

The output speed sensor value is less than
150 rpm continuously for 5 seconds or more
under the following diagnosis conditions:
• Diagnosis conditions
- Selector lever: “D”, “L” or “R” position
- Auxiliary gearbox shifting is not in progress.
- When the “D” position switch, “L” position

switch or “R” position switch is ON, the out-
put speed has not experienced 250 rpm or
more.

- After shifting the selector lever, the input

speed has experienced less than 300 rpm.

- Secondary pulley speed: 1,500 rpm or more
- TCM power supply voltage: More than 11 V

• Harness or connector

(Output speed sensor circuit is open or
shorted)

• Output speed sensor

The output speed sensor value is 90 rpm or
less continuously for 500 msec or more under
the following diagnosis conditions:
• Diagnosis conditions
- 10-msec-ago output speed: 730 rpm or

more

- TCM power supply voltage: More than 11 V

Selector lever

: “D” position

Vehicle speed

: 55 km/h (34 MPH) or more

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

Is the check result normal?

YES

>> GO TO 2.

NO

>> GO TO 6.

2.

CHECK OUTPUT SPEED SENSOR GROUND CIRCUIT

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

Is the check result normal?

YES

>> GO TO 3.

NO

>> Repair or replace malfunctioning parts.

3.

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

1. Turn ignition switch OFF.

2. Disconnect TCM connector.

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

terminal.

Is the check result normal?

YES

>> GO TO 4.

NO

>> Repair or replace malfunctioning parts.

4.

CHECK CIRCUIT BETWEEN OUTPUT SPEED SENSOR AND TCM (PART 2)

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

Is the check result normal?

YES

>> GO TO 5.

NO

>> Repair or replace malfunctioning parts.

5.

CHECK TCM INPUT SIGNALS

1. Connect all of disconnected connectors.

2. Lift the vehicle.

3. Start the engine.

4. Check frequency of output speed sensor.
