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 TCM CONNECTOR FOR POOR CONNECTION
• Switch the ignition off.
• Disconnect the TCM connector.
• Inspect for poor connection at TCM terminals 2R and 2E (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 7.

INSPECT LINE PRESSURE CONTROL SOLENOID CIRCUIT FOR SHORT TO POWER SUPPLY
• Switch the ignition ON (engine off).
• Measure the voltage at TCM (wiring harness-side) terminals 2R and 2E.
• Is there 0 V at the TCM wiring harness-side connector terminals?
|
Yes
|
Go to Step 7.
|
|
No
|
Go to the next step.

INSPECT LINE PRESSURE CONTROL SOLENOID CIRCUIT FOR SHORT TO POWER SUPPLY
• Switch the ignition off.
• Disconnect the coupler component connector.
• Switch the ignition ON (engine off).
• Measure the voltage at TCM (wiring harness-side) terminals 2R and 2E.
• 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:
• TCM terminal 2R—Coupler component terminal J
• TCM terminal 2E—Coupler component terminal I
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 7.

|
INSPECT LINE PRESSURE CONTROL SOLENOID
• Inspect the line pressure control solenoid.
• Is the line pressure control solenoid normal?
|
Yes
|
Repair or replace the wiring harness (coupler component connector—line pressure control solenoid) for short to power supply, then go to the next step.
|
|
No
|
Replace the control valve body, then 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.
