CODE RETRIEVAL PROCEDURE

„

DTC’s that start with “P1” and some
“P3” are Manufacturer specific codes
and their code definitions vary with
each vehicle manufacturer. When a
Manufacturer specific DTC is
retrieved, the LCD display shows a
list of vehicle manufacturers. Use the

DOWN

 button, as necessary, to

highlight the appropriate manufac-
turer, then press the 

ENTER

 button to display the correct

code definition for your vehicle. A confirmation message shows on
the Code Reader’s display.

- If the correct manufacturer is

shown, use the 

DOWN 

 button, 

as necessary, to highlight 

Yes

, 

then press the 

ENTER 

 button. 

-   If the correct manufacturer is not 

shown, use the 

DOWN 

 button, 

as necessary, to highlight 

No

, 

then press the 

ENTER 

 button 

to return to the list of manufacturers.

If the manufacturer for your vehicle is not shown, select 

Previous Page

 or 

Next Page

 and press the 

ENTER 

button to view other pages of the list.

If more than one DTC was retrieved, and to view Freeze Frame
Data, press and release the 

DTC/FF

 button, as necessary.

„

Each time the 

DTC/FF

 button is

pressed and released, the Code
Reader will scroll and display the
next DTC in sequence until all DTCs
in its memory have displayed.

„

Freeze Frame Data (if available) will
display after DTC #1

If more than one malfunction is present that causes more than 
one DTC to be set, only the code with the highest priority will 
contain Freeze Frame data. The code designated “

01

” on the 

Code Reader display is referred to as the PRIORITY code, 
and Freeze Frame data always refers to this code. The priority 
code is also the one that has commanded the MIL on. 

11.

When the last retrieved DTC has been displayed and the 

DTC/FF

button is pressed, the Code Reader returns to the “Priority” Code.

Determine engine system(s) condition by viewing the Code Reader’s
display for any retrieved Diagnostic Trouble Codes, code definitions and 
Freeze Frame data, and interpreting the green, yellow and red LEDs.
