INSPECTION PROCEDURE

1. 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.

a. Warm up the engine.

b. Turn the ignition switch off.

c. Connect the Techstream to the DLC3.

d. Turn the ignition switch to ON.

e. Turn the Techstream on.

f. Enter the following menus: Powertrain/Engine and ECT/Data List.

g. According to the display on the Techstream, read the Data List.

Engine and ECT:

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.

2009 TRANSMISSION AB60F Automatic Transaxle - Tundra

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
(30 MPH) or more:

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

1. INSPECT SPEED SENSOR NT INSTALLATION

a. Check the speed sensor NT installation.

OK: The installation bolt is tightened properly and there is no clearance between the sensor
and transmission case.

NG: SECURELY INSTALL OR REPLACE SPEED SENSOR NT

OK: Go to next step.

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
