Inspection Procedure

HINT:

According to the DATA LIST displayed on the intelligent tester, you can read the value of switches, sensors, actuators and other items without removing any parts. Reading the DATA LIST as the first step in troubleshooting is one method to save labor time.

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).
5. Turn on the tester.
6. Enter the following items: "DIAGNOSIS / OBD / MOBD / ECT / DATA LIST".
7. According to the display on the tester, read "DATA LIST".
   DATA LIST
   
   

   Item	Measurement Item/Range (display)	Normal Condition
   AT OIL TEMPI	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 the intelligent tester indicates 150°C (302°F) or more, there is a short circuit.

   When DTC P0713 is output and the intelligent tester indicates -40°C (-40°F), there is an open circuit.

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

   TEMPERATURE SPECIFICATION
   
   

   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 seconds). When P0713 is set, P0711 cannot be detected.

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

1. Connect the intelligent tester to the DLC3.
2. Turn the engine switch on (IG) and turn the intelligent tester on.
3. Select the items: "DIAGNOSIS / OBD/MOBD / ECT / DTC INFO / CURRENT CODES".
4. Read the DTCs using the intelligent tester.

   Result 

   RESULT REFERENCE
   
   

   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 

1. Check the transmission fluid level.

   OK: 

   Automatic transmission fluid level is correct. 

NG: ADD FLUID 

OK: Go to Next Step 

1. Remove the TCM from the transaxle.
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Tester Connection	Specified Condition
   17 (E2) - 18 (THO1)	90 Ω to 156 kΩ
   17 (E2) - Body ground	10 kΩ or higher
   18 (THO1) - Body ground	10 kΩ or higher

   HINT:

   If the resistance is out of the specified range with the ATF temperature shown in the table below, the driveability of the vehicle may decrease.

   Standard resistance 

   ATF TEMPERATURE
   
   

   ATF Temperature	Specified Condition
   10°C (50°F)	5.8 to 7.1 kΩ
   110°C (230°F)	0.23 to 0.26 kΩ

OK: REPLACE TCM 

NG: Go to Next Step 

1. Disconnect the ATF temperature sensor connector from the transmission wire.
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Tester Connection	Specified Condition
   E2 - THO1	90 Ω to 156 kΩ
   E2 - Body ground	10 kΩ or higher
   THO1 - Body ground	10 kΩ or higher

   HINT:

   If the resistance is out of the specified range with the ATF temperature shown in the table below, the driveability of the vehicle may decrease.
