VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
|
Yes
|
Perform repair or diagnosis according to the available Service Information.
• If the vehicle is not repaired, go to the next step.
|
|
No
|
Go to the next step.

INSPECT AT 15 A FUSE
• 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.

|
INSPECT VOLTAGE OF POWER SUPPLY CIRCUIT
• 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
|
INSPECT TCM CONNECTOR FOR POOR CONNECTION
• 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
|
INSPECT POWER SUPPLY CIRCUIT FOR SHORT TO GROUND
• 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 POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
• 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.

VERIFY SAME DTC IS NOT PRESENT
• Always reconnect all disconnected connectors.
• Clear the DTC using the M-MDS.
• Perform the following procedure to ensure that the DTC has been resolved:
-
1. Start the engine.
2. Warm-up the engine and transmission.
3. 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.
• Is the same DTC present?
|
Yes
|
Replace the TCM, then go to the next step.
|
|
No
|
Go to the next step.

VERIFY DTC TROUBLESHOOTING COMPLETED
• Clear the DTC using the M-MDS.
• Perform the DTC inspection using the M-MDS.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
|
|
No
|
DTC troubleshooting completed.
