2. PERFORM 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.

DIAGNOSTIC TROUBLE CODE CHART
HINT:
If a DTC is output during the DTC check, check the parts listed in the table below and proceed to the "See
page" given.
*1: "Comes on" means the Malfunction Indicator Lamp (MIL) illuminates.
*2: "DTC stored" means the ECM stores the trouble code if the ECM detects the DTC detection condition.
*3: The ATF temperature warning light blinks or a message is displayed in the combination meter.
These DTCs may be output when the clutches, brakes, gear components, etc., inside the automatic
transmission are damaged.
