Inspection Procedure

HINT:

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List.
5. According to the display on the Techstream, read the Data List.

   DATA LIST
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   A/T Oil Temperature 1	ATF temperature sensor value/Min.: -40°C (-40°F) Max.: 215°C (419°F)	After stall test: Approximately 80°C (176°F) Equal to ambient temperature while engine is cold	If value is -40°C (-40°F) or 215°C (419°F), ATF temperature sensor circuit is opened or short circuited

   HINT:

   • When DTC P0712 is output and the Techstream output is 150°C (302°F) or more, there is a short circuit.
   • When DTC P0713 is output and the Techstream output is -40°C (-40°F), there is an open circuit. Check the temperature displayed on the Techstream in order to check if a malfunction exists.
     TEMPERATURE REFERENCE
     
     

     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 set in approximately 0.5 seconds.
   • 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 Techstream to the DLC3.
   2. Turn the ignition switch to ON.
   3. Turn the Techstream on.
   4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
   5. Read the DTCs using the Techstream.

      Display (DTC output)	Proceed to
      Only P0711 is output	A
      P0711 and other DTCs are output	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 
   1. Check the transmission fluid level (see AUTOMATIC TRANSMISSION FLUID  ).

      OK: 

      Automatic transmission fluid level is correct. 

   NG: ADD FLUID 

   OK: REPAIR OR REPLACE TRANSMISSION WIRE
