When an emission-related fault occurs, certain vehicle conditions are recorded by the

on-board computer. This information is referred to as a Freeze Frame data. The infor-

mation is a snapshot of the operating conditions at the time of a fault. This data can be

overwritten by faults with a higher priority. If codes were erased, then freeze frame data

may not be stored in vehicle memory.

Select View Freeze Data and press ENTER. If freeze-frame data exists, then use the

arrow keys to view the DTCs and parameter identification data (PIDs).

If more than one computer module responds with freeze frame data, then the frame

Pressing the UP/DOWN arrow keys scrolls through the digits. Once the desired digit is

displayed, press the ENTER key and the ^ symbol moves under the next digit. Repeat for

the remaining digits in the code. After entering the last digit, the ENTER key displays the

definition. Once in the definition screen, press the UP/DOWN arrow keys to view the

previous or next code definition.

Performing a thorough visual and hands-on under-

the -hood inspection before starting any diagnostic pro-

cedure is essential. Many problems can be found this

way. Visually inspect for the following:

 Has the vehicle been serviced recently? Sometimes

things are reconnected in the wrong place, or not at

all.

 Do not take shortcuts. Inspect hoses and wiring

which may be difficult to see because of location

(under air cleaner housing, alternators and similar

components).

 Inspect the air cleaner and ductwork for defects.

 Check sensors and actuators for damage.
