DATA LIST

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.

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.

Warm up the engine.
Turn the engine switch off.
Connect the Techstream to the DLC3.
Turn the engine switch on (IG).
Turn the Techstream on.
Enter the following menus: Powertrain / ECT / Data List / SPD (NT).

Read the Data List according to the display on the Techstream.

Powertrain > ECT > Data List

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
SPD (NT)	Input shaft speed	Min.: 0 rpm Max.: 12750 rpm	Lock-up is ON (after warming up engine): Input turbine speed (NT) is equal to engine speed OFF (idling with shift lever in N): Input turbine speed (NT) is nearly equal to engine speed	Data is displayed in increments of 50 rpm

Powertrain > ECT > Data List

Tester Display
SPD (NT)

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 malfunction, improper installation, or intermittent connection malfunction in the circuit.
