Diagnostic Fault Codes

The engine ECM will record three types of fault codes; Electronic Control System Faults, Protection
System Faults and Maintenance Indicators. All faults recorded will be ACTIVE or INACTIVE. Not all
faults will light an indicator when they are ACTIVE.
Illuminated Lamps:
WARNING - Indicates a failure has occurred, but the motorhome can be operated without pro-
gressive damage. The motorhome should be serviced to diagnose the failure and repaired at the
first opportunity. The indication is not considered an emergency.
Solid RED STOP ENGINE - Indicates a major failure has occurred that can result in progressive
damage or affect safe operation of the motorhome. The motorhome should be shut down as soon
as safely possible and remain shut down until the fault can be repaired.
Flashing RED STOP ENGINE - Indicates the engine control system has started the shut down
sequence. The shut down timer will give the operator 30 seconds to find a safe stopping point.
CHECK ENGINE - Indicates the engine requires maintenance or fluids. The motorhome should
be serviced to correct the problem. If ignored, some maintenance conditions can cause improper
engine operation and even progressive damage.

1. Turn the ignition key OFF.
2. Turn the ignition key ON immediately apply three full throttle application.

a. If no active codes are recorded, both lamps will remain illuminated.

ed fault.
