  CODE RETRIEVAL PROCEDURE 
OBD2 41 
  Red LED – Indicates there is a 
problem with one or more of the 
vehicle’s systems. The red LED is 
also used to indicate that DTC(s) 
are present (displayed on the 
Diagnostic Tool’s screen). In this 
case, the Multifunction Indicator 
(Check Engine) lamp on the 
vehicle’s instrument panel will be 
illuminated. 
  Flashing Red and Yellow LEDs – Indicates that a "permanent" 
code has been set, and one or more of the vehicle’s monitors 
has failed its diagnostic testing. A "permanent" DTC can be 
cleared  only by the vehicle's computer following successful 
completion of the monitor that caused the fault to set. 
  DTC’s that start with “P0”, “P2” and some “P3” are considered 
Generic (Universal). All Generic DTC definitions are the same 
on all OBD2 equipped vehicles. The Diagnostic Tool 
automatically displays the code definitions for Generic DTC’s. 
  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 UP 
 and DOWN   buttons, as necessary, to highlight 
the appropriate manufacturer, then press the ENTER/FF 
button to display the correct code definition for your vehicle. A 
confirmation message shows on the LCD display. 
- If the correct manufacturer is 
shown, press the ENTER/FF 
button to continue. 
-  If the correct manufacturer is not 
shown, press the DTC SCROLL 
 button to return to the list of 
vehicle manufacturers. 
If the manufacturer for your vehicle is not listed, use the 
UP 
 and  DOWN   buttons, as necessary, to select 
Other manufacturer and press the ENTER/FF 
 button 
for additional DTC information. 
If the Manufacturer Specific 
definition for the currently dis-
played code is not available, an 
advisory message shows on the 
Diagnostic Tool’s LCD display.
