1. DATA LIST
HINT: Using the Techstream to read the Data List allows values or status 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.
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) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG) and turn the Techstream on.
