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
SPD(NT)	Input shaft speed/ Min.: 0 rpm Max.: 12,750 rpm	Lock up is ON (after warming up engine): Input turbine speed (NT) is equal to engine speed OFF (idling with shift lever on N): Input turbine speed (NT) is nearly equal to engine speed	Data is displayed in increments of 50 rpm

HINT:

SPD(NT) is always 0 while driving:
Open or short in the sensor or circuit.
SPD(NT) is always more than 0 and less than 300 rpm while driving the vehicle at 50 km/h (31 mph) or more:

Sensor trouble, improper installation, or intermittent connection trouble of the circuit.

INSPECT SPEED SENSOR INSTALLATION
1. Check the speed sensor NT installation.
OK: Installation bolt is tightened properly and there is no clearance between the sensor and transmission case.

NG: SECURELY INSTALL SENSOR OR REPLACE SENSOR

INSPECT SPEED SENSOR NT

Disconnect the T17 sensor connector from the transmission.
Measure the resistance of the sensor.

1 - 2	20°C (68°F)	560 to 680 Ω

NG: REPLACE SPEED SENSOR NT

OK: GO TO Next Step

CHECK WIRE HARNESS (SPEED SENSOR - ECM)
1. Check wire harness (see ECM ).
NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM
