Inspection Procedure

WARNING: This page is about a different car, the 2008 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

DATA LIST

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.

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 Techstream to the DLC3.
Turn the engine switch on (IG) position.
Turn the Techstream on.
Select the item "Powertrain / Engine and ECT / Data List".

According to the display on the tester, read the "Data List".

DATA LIST

Item	Measurement Item/Range (display)	Normal Condition
A/T Oil Temperature 1	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 Techstream output is 150°C (302°F) or more, there is a short circuit.

When DTC P0713 is output and Techstream output is -40°C (-40°F), there is an open circuit.

Measure the resistance between terminal OIL and body ground.

TERMINALS RESISTANCE 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.

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 CHART

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.

TERMINALS TEMPERATURE CHART

ATF Temperature	Specified Condition
10°C (50°F)	3 to 8 kΩ
25°C (77°F)	2.5 to 4.5 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
E4-27 (OIL) - Body ground	10 kΩ or higher
E4-26 (EOIL) - Body ground	↑

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: REPLACE ECM
