Inspection Procedure

WARNING: This page is about a different car, the 2006 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 DATA LIST DETAIL , 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 / ENHANCED OBD II / DATA LIST.

Follow the instructions on the tester and read the DATA LIST.

DATA LIST DETAIL

Item	Measurement Item/Range (Display)	Normal Condition	Diagnostic Note
AT FLUID TEMP	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 during cold soak	If value is -40°C (-40°F) or 215°C (419°F), ATF temperature sensor circuit is opened or short circuited

HINT:

When DTC P2742 is output and the intelligent tester output is 150°C (302°F) or more, there is a short circuit.

When DTC P2743 is output and the intelligent tester output is -40°C (-40°F), there is an open circuit. Measure the resistance between terminal THO2 (OT2) and the body ground.

TERMINALS RESISTANCE SPECIFICATION

Temperature Displayed	Malfunction
-40°C (-40°F)	Open circuit
150°C (302°F) or more	Short circuit

INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)

Disconnect the E1 wire connector.

Measure the resistance of the transmission wire.

Standard resistance

TERMINALS RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
1 (OT2-) - 9 (OT2+)	79 Ω to 156 kΩ
1 (OT2-) - Body ground	10 kΩ or higher
9 (OT2+) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE TRANSMISSION WIRE

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the E5 and E6 ECM connectors.

Measure the resistance of the wire harness side connectors.

Standard resistance

TERMINALS RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
E6-32 (THO2) - E5-28 (E2)	25 Ω to 156 kΩ
E6-32 (THO2) - Body ground	10 kΩ or higher
E5-28 (E2) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
