CODE RETRIEVAL PROCEDURES – KOEO TEST 

 

 

OBD1 73 

 

„

 

The LCD display shows instructions to 
prepare the vehicle for the KOEO Test. 

4.

 

Start and warm-up engine to normal 
operating temperature. Press the 

 

button to continue. 

5.

 

Turn ignition key OFF and wait for the on 
screen prompt. If you wish to exit the 
KOEO test at this time, press the 

 

button. 

6.

 

Turn the ignition ON. DO NOT start the engine. If your vehicle is 
equipped with one of the following engine types, perform the added 
procedures described below: 

„

 

For 4.9L engines with standard transmission: Press and hold 
the clutch until all codes are sent (steps 7 through 9). 

„

 

For 7.3L diesel engines: Press and 
hold accelerator until all codes are sent 
(steps 7 through 9). 

„

 

For 2.3L turbo engines with octane 
switch: Put switch in premium position. 

7.

 

Press the ENTER 

  button to continue. 

8.

 

While codes are being retrieved, a "One 
moment please KOEO test is in 
progress..." message shows on the Scan 
Tool's LCD display. 

As soon as the ignition is turned "on", the vehicle's computer 
enters the Self-Test mode. Clicking sounds will be heard 
coming from the engine. This is normal. It indicates that the 
vehicle's computer is activating relays, solenoids, and other 
components to check their operation. 

WARNING: On some vehicles equipped with an Electric 
Cooling Fan, the computer activates the cooling fan to 
check its operation. To avoid injury, keep hands or any 
part of your body a safe distance from the engine during 
this test. 

„

 

If the Scan Tool fails to link to the 
vehicle's computer, a "Vehicle is not 
responding" message shows on the 
Scan Tool 's LCD display. Do the 
following: 

-  Verify the ignition is ON. 

-  Check the cable connections at the 

Scan Tool and at the vehicle's DLC. 

-  Turn the ignition OFF, wait 10 seconds, then turn back ON to 

reset the computer.
