HINT:

Normal Condition: If no conditions are specifically stated for "idling", the shift lever is in the N or
P position, and the A/C switch is OFF and all accessory switches are OFF.

2. ACTIVE TEST

HINT:

Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be
operated without removing any parts. This non-intrusive functional inspection can be very useful because
intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests
early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while
performing Active Tests.

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/Active Test.

g. According to the display on the Techstream, perform the Active Test.

SPD (NT)

Input shaft speed/
Min.: 0 RPM, Max.:
12750 RPM



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

SPD (SP2)

Output shaft speed/
Min.: 0 km/h (0
mph), Max.: 255
km/h (158 mph)

Vehicle stopped: 0
km/h (0 mph)
(output shaft speed is
equal to vehicle
speed)

NOTE:

If the forced activation of the solenoid does not finish, turn the
ignition switch off.
