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 TEMP2 | ATF temperature sensor No. 2 value/ Min.: -40°C (-40°F) Max.:215°C(419°F) |
|
If value is -40°C (-40°F) or 215°C (419°F), ATF temperature sensor No. 2 circuit is opened or short circuit |
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.
TEMPERATURE 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
RESISTANCE SPECIFICATIONTester 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
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 SPECIFICATIONTester Connection Specified Condition E6-32 (THO2) - E5-28 (E2) 25Ω to 156kΩ 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
OK: REPLACE ECM
