DATA LIST / ACTIVE TEST

1. DATA LIST
HINT: Using the Data List displayed by the Techstream, you can read the values of the switches, sensors, actuators and so on without parts removal. Reading the Data List as the first step of troubleshooting is one method of shortening labor time.
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.

(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
