DISPLAY FUNCTIONS
6. CanOBD2&1 Scan Tool Internal Battery icon - When visible,
indicates the CanOBD2&1 Scan Tool batteries are “low” and should
be replaced. If the batteries are not replaced when the battery sym-
bol
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 dis-
played 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. FREEZE FRAME icon - Indicates that there is Freeze Frame data
from “Priority Code” (Code #1) stored in the vehicle’s computer
memory.
10. HISTORY icon - Indicates the currently displayed DTC is a
“History” code.
11. PENDING icon - Indicates the currently displayed DTC is a
“Pending” code.
12. 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.
13. Code Number Sequence - The CanOBD2&1 Scan 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 prior-
ity 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.
14. Code Enumerator - Indicates the total number of codes retrieved
from the vehicle’s computer.
15. Generic DTC icon - When visible, indicates that the currently
displayed DTC is a “Generic” or “Universal” code. (This function is
applicable to OBD2 systems only.)
16. Enhanced DTC icon - When visible, indicates that the current-
ly displayed DTC is a Manufacturer Specific Code. (This function
is applicable to OBD2 systems only.)
