Using the Diagnostic Tool
CODE RETRIEVAL PROCEDURE
OBD2 39
The Diagnostic Tool will display a
code only if codes are present in the
vehicle’s computer memory. If no
codes are present, a “No DTC’s are
presently stored in the vehicle’s
computer” is displayed.
The Diagnostic Tool is capable of re-
trieving and storing up to 32 codes in
memory, for immediate or later
viewing.
7. To read the display:
Refer to
DISPLAY FUNCTIONS on page 13 for a descrip-
tion of LCD display elements.
A visible icon indicates that the Diagnostic Tool is being
powered through the vehicle’s DLC connector.
A visible icon indicates that the Diagnostic Tool is linked to
(communicating with) the vehicle’s computer.
The I/M Monitor Status icons indicate the type and number of
Monitors the vehicle supports, and provides indications of the
current status of the vehicle’s Monitors. A solid Monitor icon
indicates the associated Monitor has run and completed its
testing. A blinking Monitor icon indicates the associated Monitor
has not run and completed its testing.
The upper right hand corner of the dis-
play shows the number of the code
currently being displayed, the total
number of codes retrieved, the type of
code and whether or not the displayed
code commanded the MIL on. If the
code being displayed is a PENDING
code, the PENDING icon is shown.
Freeze Frame data is always associated with the “Priority
Code” (identified as Code #1 in the Code Reader’s
display). If the FREEZE FRAME icon is lit when the
“Priority Code” (Code #1) is displayed on the Code
Reader’s screen, it indicates that there is Freeze Frame
data associated with this code, and the vehicle’s computer
has saved it in its memory.
The Diagnostic Trouble Code (DTC) and related code definition
are shown in the lower section of the LCD display.
In the case of long code definitions, a small arrow is
shown in the upper/lower right-hand corner of the code
display area to indicate the presence of additional
information. Use the
and buttons, as necessary,
to view the additional information.
8. Read and interpret Diagnostic Trouble Codes/system condition
using the LCD display and the green, yellow and red LEDs.
