Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save 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 ignition switch OFF.
Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
Turn the ignition switch ON.
Turn the intelligent tester ON.
Enter the following menus: DIAGNOSIS / OBD/MOBD / ECT / DATA LIST.
Follow the instructions on the tester and read the DATA LIST.

DATA LIST

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
A/T OIL TEMPI	ATF temperature sensor No. 1 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 No. 1 circuit is opened or short circuit

HINT:

When DTC P0712 is output and the intelligent tester output is 150°C (302°F) or more, there is a short circuit.
When DTC P0713 is output and the intelligent tester output is -40°C (-40°F), there is an open circuit. Measure the resistance between terminal THO1 (OT) and the 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 set in approximately 0.5 seconds. It is not necessary to inspect the circuit when P0711 is set.

INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)

Disconnect the E1 wire connector.
Measure the resistance of the transmission wire.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
2 (OT-) -10 (OT+)	79 Ω to 156 kΩ
2 (OT-) - Body ground	1 MΩ or higher
10 (OT+) - Body ground	1 MΩ or higher

HINT:

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

Standard resistance

RESISTANCE SPECIFICATION

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

NG: REPAIR OR REPLACE TRANSMISSION WIRE

OK: GO TO Next Step

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the E5 and E6 ECM connectors.
Measure the resistance of the wire harness side connectors.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
E6-24(THO1) - E5-28(E2)	79 Ω to 156 kΩ
E6-24 (THO1) - Body ground	10 kΩ or higher
E5-28 (E2) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
