5.24 KOER Cylinder Contribution
This test is available on some Ford trucks equipped with
a diesel engine. The KOER Cylinder Contribution is an
on-demand test performed with the engine running, the
A/C off and engine oil temperature above 76.6°C
(170°F). This test determines that all cylinders are con-
tributing equally to engine performance.
The PCM first tests the cylinders in numeric order (1 –
8) for a bad/weak cylinder. If all cylinders check good, a
4 cylinder test is then executed (if a weak cylinder is
detected in the 8 cylinder test, the four cylinder test will
not be started).
During the test, the engine emits smoke, and the RPM
varies with each check (there is no audible difference in
RPM if a bad/weak cylinder is detected).
WARNING
Exhaust gases are harmful or fatal. Always
operate vehicle in a well-ventilated area.
CAUTION
The KOER cylinder contribution test is
done with the engine running. Set the
parking brake and place the transmission
in PARK or NEUTRAL (automatic transmis-
sions only). Do not over-rev the engine.
Observe all safety precautions.
From the On Demand Tests Menu:

6 Troubleshooting
6.1 Error Messages
Check the following if an error message displays:
• Verify ignition key is in the ON and not in the ACCES-
SORIES position.
• Make sure the DLC Cable is attached to vehicle’s
data link connector (DLC) and scan tool.
• Look at DLC and check for cracked or recessed pins,
or for any substance that could prevent a good
electrical connection.
• Test for continuity between the DLC wiring and the
computer. In an extreme case, there may be a bro-
ken wire.
• Check for bent or broken pins.
• With the engine off, check for blown fuses in the
vehicle fuse box.
• Make sure the vehicle’s control module has a good
ground. If the computer case is grounded, then
clean the connection and apply a conductive (dielec-
tric) grease to the mating surfaces.
