Toyota Tundra (2015 year). Manual — part 1093
HINT:
*1: Excluding throttle valve opening percentage due to Idle Speed Control (ISC).
*2: Data List values are only displayed when performing the following Active test: Control the VVT Linear
(Bank 1), Control the VVT Linear (Bank 2), Control the Exhaust Linear (Bank 1) and Control the VVT
Exhaust Linear (Bank 2). For other Active test, the Data List value will be 0.
Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in N or P, the
A/C switch should be OFF, and all accessory switches should be 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.
