Go to the next step.

2

• Verify related Service Bulletins and/or on-line repair 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.

3

• Switch the ignition off.

• Disconnect the TCM connector.

• Inspect for poor connection at TCM terminals 1A and 1B (such as damaged/pulled-out pins, corrosion).

• Are terminals normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 10.

4

• Inspect for continuity between the TCM terminals 1A and 1B (wiring harness-side).

• Is there continuity?

Yes

Go to the next step.

No

Go to Step 7.

5

• Inspect for continuity between the TCM terminals (wiring harness-side) and body ground.

• Terminal 1A and body ground

• Terminal 1B and body ground

• Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• Turbine sensor terminal B—TCM terminal 1A

• Turbine sensor terminal A—TCM terminal 1B

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has a short to ground.

Go to Step 10.

6

• Switch the ignition ON (engine off).

• Measure the voltage at TCM (wiring harness-side) terminals 1A and 1B.

• Is there 0 V at the TCM wiring harness-side connector terminals?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• Turbine sensor terminal B—TCM terminal 1A

• Turbine sensor terminal A—TCM terminal 1B

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has a short to power supply.

Go to Step 10.

7

• Switch the ignition off.

• Disconnect the turbine sensor connector.

• Inspect for poor connection at turbine sensor terminals A and B (such as damaged/pulled-out pins, corrosion).

• Are terminals normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 10.

8

• Inspect the turbine sensor.

  (See TURBINE SENSOR INSPECTION [SJ6A-EL].)

• Is the turbine sensor normal?

Yes

Go to the next step.

No

Replace the turbine sensor, then go to Step 10.

(See TURBINE SENSOR REMOVAL/INSTALLATION [SJ6A-EL].)

9

• Inspect for continuity between turbine sensor terminals (wiring harness-side) and TCM terminals (wiring harness-side).

• Terminal B and terminal 1A

• Terminal A and terminal 1B

• Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• Turbine sensor terminal B—TCM terminal 1A

• Turbine sensor terminal A—TCM terminal 1B

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has an open circuit.

Go to the next step.

10

• Always reconnect all disconnected connectors.

• Clear the DTC using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Perform the following procedure to ensure that the DTC has been resolved:

• Start the engine.

• Warm-up the engine and transmission.

• Drive the vehicle in D position and make sure that the gears shift smoothly from 1GR to 6GR.

• Perform the DTC inspection using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Is the same DTC present?

Yes

Replace the TCM, then go to the next step.

(See TCM REMOVAL/INSTALLATION [SJ6A-EL].)

No

Go to the next step.

11

• Clear the DTC using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Perform the DTC inspection using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (SJ6A-EL)].)

No
