Arming triggers:
1. Select the Trigger icon.
2. Select Arm Triggers .
The trigger point lines change color to indicate an armed condition
(
Figure 4-32
).
All set PID triggers are armed simultaneously (if more that one is set). Once armed
it remains armed until you clear it or the trigger is activated.

About Activated Triggers
A trigger is activated (displays red flag) when a PID value meets an upper/
lower limit (trigger point).
When a trigger is activated:
•
Data collection is briefly paused as the Scanner captures a short recording of
PID data (before and after the trigger event), and saves it as a data file.
•
A gray cursor line is displayed to indicate the point at which the data was
paused or saved.
•
An audible alarm is sounded
•
A message displays indicating a data file was saved.
•
Data collection continues.
•
The activated PID trigger is disarmed.
Note
- if a different PID trigger is
activated subsequently, an additional data file will be recorded.
•
A red cursor line is displayed on the graph of the PID with the activated trigger
to indicate where the trigger occurred. A green cursor line is displayed on all the
other PID graphs to indicate their relationship to where the trigger occurred.
•
The trigger menu options are:
- Clear Trigger —deletes the highlighted trigger
- Arm Trigger —arms the trigger to capture data
- Clear All Triggers —deletes all set triggers

Functional Tests provides access to vehicle-specific subsystem tests.
NOTE
Functional Test functionality, availability, navigation and terminology is vehicle
manufacturer dependent, and will vary.
Typical functional tests:
•
Information Tests —read-only tests (i.e. selecting “VIN” to display the VIN of
the vehicle).
•
Toggle Tests —component state change tests (i.e. switching a solenoid, relay,
or switch, between two operating states).
•
Variable Control Tests —command variable value tests (i.e. varying spark
timing in 1° increments or EGR valve duty cycle in 10% increments).
•
Reset Tests —reset the adaptive, or learned, values that are stored in the
vehicle electronic control module memory.
•
Scripted Tests —preconfigured tests that are run when performing certain
repairs (i.e. bleeding brakes with ABS).
