STEP

INSPECTION

ACTION

1

NOTE:

• Recording can be facilitated using the screen capture of the PC function.

• Record the freeze frame data/snap shot data.

—

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

• Connect the TCM connector.

• Switch the ignition off.

• Inspect the AT 15 A fuse for malfunction.

• is it normal?

Yes

Go to the next step.

No

• If the AT 15 A fuse has been melted, replace it, then go to the Step 8.

• If the AT 15 A fuse is not installed correctly, install it correctly, then go to Step 8.

4

• Inspect the voltage between TCM terminal (wiring harness-side) and body ground.

• TCM terminal 2AE

• TCM terminal 2AI

• Is the voltage B+?

Yes

Go to the next step.

No

Go to Step 6.

5

• Switch the ignition off.

• Disconnect the TCM connector.

• Inspect for poor connection at TCM terminals 2AE and 2AI (such as damaged/pulled-out pins, corrosion).

• Is terminal normal?

Yes

Go to Step 8.

No

Repair or replace the connector and/or terminal, then go to Step 8.

6

• Disconnect the positive battery cable.

• Inspect for continuity between the fuse terminals and body ground.

• AT 15A fuse terminal and body ground

• Is there continuity?

Yes

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

• TCM terminal 2AE—AT 15 A fuse

• TCM terminal 2AI—AT 15 A fuse

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 8.

No

Go to the next step.

7

• Inspect for continuity between TCM terminal and fuse terminals (wiring harness-side).

• Terminal 2AE and AT 15 A fuse

• Terminal 2AI and AT 15 A fuse

• 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:

• TCM terminal 2AE—AT 15A fuse

• TCM terminal 2AI—AT 15A fuse

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.

8

• 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.

9

• 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

DTC troubleshooting completed.
