Engine Diagnostics
Check Engine Light
The Workman HDX is equipped with a check engine
light that indicates if the engine electronic controller is
functioning correctly. The check engine light is located
on the dash panel (Fig. 4).

Remove bed support and lower bed.
When the ignition switch is moved to the ON position
and the engine electronic controller is functioning pro-
perly, the check engine light will be illuminated for
approximately three (3) seconds and then will turn off.
The light should remain off during normal vehicle opera-
tion.
NOTE: If a component problem exists when engine is
initially started, the check engine light will stay illumi-
nated to identify the problem. In some instances, how-
ever, a recurring component problem might not be
detected until after the engine has been run for some
time.
Duringvehicleoperationifaproblem occurswiththeen-
gine management system, the check engine light on the
dash panel will illuminate. If possible, allow engine to
continue running to prevent the controller from resetting
should the engine be stopped. A component failure
code can be retrieved to identify the engine component
that has caused the check engine light to illuminate.
