1. DATA LIST 

   HINT:

   According to the DATA LIST displayed by the intelligent tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor time.

   NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
   1. Warm up the engine.
   2. Turn the engine switch off.
   3. Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
   4. Turn the engine switch on (IG) position.
   5. Turn on the tester.
   6. Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST".
   7. According to the display on the tester, read the "DATA LIST".
   DATA LIST
   
   

   Item	Measurement Item/Range (display)	Normal Condition
   AT OIL TEMP1	ATF Temp. Sensor Value/min.: -40°C (-40°F) max.: 215°C (419°F)	After Stall Test; Approx. 80°C (176°F) Equal to ambient temperature when cold soak

   HINT:

   When DTC P0712 is output and OBD II scan tool or intelligent tester output is 150°C (302°F) or more, there is a short circuit.

   When DTC P0713 is output and OBD II scan tool or intelligent tester output is -40°C (-40°F), there is an open circuit.

   Measure the resistance between terminal THO1 (OT) and body ground.

   MALFUNCTION CHART
   
   

   Temperature Displayed	Malfunction
   -40°C (-40°F)	Open circuit
   150°C (302°F) or more	Short circuit

HINT:

If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 second). When P0713 is set, P0711 cannot be detected.

It is not necessary to inspect the circuit when P0711 is set.

1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711) 
   1. Connect the OBD II scan tool or the intelligent tester to the DLC3.
   2. Turn the engine switch on (IG) position and push the OBD II scan tool or the intelligent tester main switch ON.
   3. When you use intelligent tester:

      Select the item "DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES".

   4. Read the DTCs using the OBD II scan tool or the intelligent tester.

      Display (DTC output)	Proceed to
      Only "P0711" is output	A
      "P0711" and other DTCs	B

      HINT:

      If any other codes besides "P0711" are output, perform troubleshooting for those DTCs first.

   B : GO TO  DTC CHART  

   A : GO TO NEXT STEP 

2. CHECK TRANSMISSION FLUID LEVEL 

   OK: Automatic transmission fluid level is correct. 

NG : ADD FLUID 

OK : REPLACE TRANSMISSION WIRE
