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 ENTER/LD button
to return to the Ford EEC-IV System menu.
6. When prompted by the CanOBD2&1 Scan Tool, 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 pre-
mium position.
7. Press the ENTER/LD button to continue.
8. While codes are being retrieved, a "One
moment please KOEO test is in
progress..." message shows on the
CanOBD2&1 Scan Tool's 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 oper-
ation.
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 CanOBD2&1 Scan Tool fails to
link to the vehicle's computer, a
"Vehicle is not responding" message
shows on the CanOBD2&1 Scan
Tool's display. Do the following:
- Verify the ignition is ON.
- Check the cable connections at
the CanOBD2&1 Scan Tool and at
the vehicle's DLC.
- Turn the ignition OFF, wait 10 seconds, then turn back ON to
reset the computer.
BE SURE to perform the added procedures in step 6,
if appropriate for your vehicle, during code retrieval.
