2-2. Fault Codes
2-2-1. Description of fault codes
The electronic engine control system can display and record certain detectable fault conditions. These failures are
displayed as fault codes, which make troubleshooting easier. The fault codes are retained in the ECM.
There are two types of diagnostic codes:
Engine electronic control system fault codes are to inform the operator that there is a problem with the control
system that will require troubleshooting.
Information and engine protection fault codes are to inform the operator that the control system has detected an
engine condition outside the normal operating range.
All fault codes recorded will either be active (fault code is currently active on the engine) or inactive (fault code
was active at some time, but is not currently active).
The “ENGINE STOP” light is red and indicates the need to stop the engine as soon as it can be safely done. The
engine must remain shutdown until the fault can be repaired.
The “WARNING” light is orange and indicates the need to repair the fault at the first available opportunity.
Maintenance type fault codes will flash the orange warning light for 30 seconds after the starter switch is turned to
the “ON” position when one of the following occurs: maintenance is required (if maintenance monitor is turned on)
or if water-in-fuel is detected.
If the warning light flashes for 30 seconds at starter switch is “ON” position and water is drained from the primary,
fuel sedimenter, then the secondary filter must be replaced.
