Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded on the repair order?

Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related Service 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.

•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 6.
No
Go to the next step.
4
INSPECT TFT SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition OFF (LOCK).
•  Inspect for continuity between coupler component terminals B8 and B7.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
5
INSPECT TFT SENSOR
•  Inspect the TFT sensor.
•  Is there any malfunction?
Yes
Replace the TFT sensor, then go to the next step.
(See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No
Go to the next step.
6
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all the 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 to normal operating temperature.
3.  Drive the vehicle in D position for 150 s or more.
•  Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No
Go to the next step.
7
VERIFY NO DTCs ARE PRESENT
•  Perform the “Reading DTCs Procedure”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [AY6A-EL, AY6AX-EL].)
No
DTC troubleshooting completed.
