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.

Warm up the engine.
Turn the engine switch off.
Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
Turn the engine switch on (IG) position.
Turn on the tester.
Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST".
According to the display on 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

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 OIL and body ground.

TEMPERATURE DISPLAY

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.

INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)

Disconnect the transmission wire connector from the transmission.
Measure the resistance according to the value(s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
1 (E2) - 9 (OIL)	79 Ω to 156 kΩ
1 (E2) - Body ground	10 kΩ or higher
9 (OIL) - Body ground	10 kΩ or higher

HINT:

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

Standard resistance

ATF TEMPERATURE SPECIFICATION

ATF Temperature	Specified Condition
20 °C (68°F)	3 to 4 kΩ
110°C (230°F)	0.22 to 0.28 kΩ

NG : REPAIR OR REPLACE TRANSMISSION WIRE

OK : GO TO NEXT STEP

CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)

Connect the transmission wire connector to the transmission.
Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
E4-27 (OIL) - E4-26 (EOIL)	79 Ω to 156 kΩ

Measure the resistance according to the value(s) in the table below.

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
E4-27 (OIL) - Body ground	10 kΩ or higher
E4-26 (EOIL) - Body ground

NG : REPAIR OR REPLACE HARNESS OR CONNECTOR

OK : REPLACE ECM
