Engine Warning Lamps
General Information
The following engine warning lamps
cover only the lamps controlled by the
engine’s Electronic Control Module
(ECM). Please refer to the vehicle
Operator's and Engine Aftertreatement
Systems manual for additional warning
lamp information.
Check Engine Lamp
The check engine warning lamp will
illuminate when a problem exists,
but the vehicle can still be safely
driven. The vehicle should be serviced
to correct the problem, but the
situation should not be considered an
emergency.
The lamp will also illuminate when a
DPF regeneration or addition of Diesel
Exhaust Fluid is required. Another
function of the check engine lamp is to
warn the operator of an impending idle
shutdown. When the idle shutdown
timer is 30 seconds from expiring, the
engine ECM begins flashing the check
engine warning lamp once per second.
When the timer expires, the ECM will
turn off the warning lamp and shut
down the engine.
