The amber
Check Engine
,
or Engine Warning
,
light indicates a non-critical system fault with
the engine has occurred. The operator can drive the vehicle to the end of their shift and call
service to remedy the problem.
The red
Stop
Engine
light indicates a serious engine fault that may result in engine damage
has occurred and the vehicle should be shut down as soon as it is safe to do so. The engine
should remain shut down until serviced by an authorized dealer.
The
Malfunction Indicator (MIL)
light illuminates when a fault has occurred on an emission
related component. The engine and after treatment system should be diagnosed and
serviced at the next available opportunity.
If the MIL and Stop Engine Lamp illuminate together, the vehicle should be stopped as soon
as it is safe to do so. The vehicle should be serviced by an authorized dealer.
The
Diesel Particulate Filter (DPF)
light will illuminate when a regeneration is necessary.
There are progressive stages of need for regeneration indicated by this light:
1. On solid (low to medium levels of particulate build up). The vehicle requires regeneration
but should be able to complete its mission before a regeneration is performed.
— Ensure the Regen Inhibit Switch is not activated.
— Initiate a DPF regeneration by switching to a more challenging duty cycle (such as
highway driving for at least 20 minutes or pumping)
— OR perform a parked regeneration.
2. Flashing (medium to high levels of particulate build up). The vehicle requires a
regeneration as soon as possible).
— Perform a regeneration by switching to a more challenging duty cycle or a parked
regeneration.
3. Flashing with amber Check Engine light (high level of particulate build up). A DPF
regeneration is required immediately.
— An automatic regeneration will not initiate. The operator must perform a parked
regeneration.
4. If a parked regeneration is not performed the red Stop Engine lamp will illuminate.
— As soon as it is safe to do so, the vehicle should be
stopped
and remain shut down
until serviced by an authorized dealer.
