DISPLAY FUNCTIONS
6. Tool Internal Battery icon - When visible, indicates the Tool
batteries are “low” and should be replaced. If the batteries are not
replaced when the battery symbol
is "on", all 3 LEDs will light
up as a last resort indicator to warn you that the batteries need
replacement. No data will be displayed on screen when all 3 LEDs
are lit.
7. DTC Display Area - Displays the Diagnostic Trouble Code (DTC)
number. Each fault is assigned a code number that is specific to
that fault.
8. Test Data Display Area - Displays DTC definitions, Freeze Frame
data, and other pertinent test information messages.
9. MIL icon - Indicates the status of the Malfunction Indicator Lamp
(MIL). The MIL icon is visible only when a DTC has commanded the
MIL on the vehicle’s dashboard to light.
10. CODE icon - Identifies the Code Number Sequence display area.
11. PENDING icon - Indicates the currently displayed DTC is a
“Pending” code. (This function is applicable to OBD2 systems
only.)
12. Code Number Sequence - The Tool assigns a sequence number
to each DTC that is present in the computer’s memory, starting
with “01.” This number indicates which code is currently displayed.
Code number “01” is always the highest priority code, and the one
for which “Freeze Frame” data has been stored. (Freeze Frame
data is applicable to OBD2 systems only.)
If “01” is a “Pending” code, there may or may not be
“Freeze Frame” data stored in memory.
13. Code Enumerator - Indicates the total number of codes retrieved
from the vehicle’s computer.
