2-2. Fault Codes
2-2-1. Fault detection
Faults are detected while the starter switch is on, during the operation of the machine itself. If a fault becomes
active (currently detected) at this time, a fault is logged in memory and a snapshot of engine parameters is
logged. In addition, certain faults may illuminate the warning lamp (orange) or the stop lamp (red).
2-2-2. Fault lamps
The controller systems use 4 indicator lamps: the “ ENGINE STOP ”, “ WARNING ”, “ WAIT TO START ” and
“ EGT. WARNING . If the starter switch is turned on but the diagnostic switch remains off, the indicator lamps will
illuminate for approximately two seconds and then go off, one after the other, to verify they are working and wired
correctly. They all go on and then go off one at a time, at an interval of approximately 0.5 seconds each.
“ ENGINE STOP ” Lamp - The “ ENGINE STOP ” lamp provides critical operator messages. These messages
require immediate and decisive operator response. The “ ENGINE STOP ” lamp is also used to flash out
diagnostic fault codes.
“
WARNING ” Lamp - The “ WARNING ” lamp provides important operator messages. These messages require
timely operator attention. The “ WARNING ” lamp is also used to delineate diagnostics fault codes.
“ WAIT TO START ” Lamp - The “ WAIT TO START ” lamp indicates that the pre-start intake manifold heater
warm-up sequence is active. A Cummins supplied grid heater will automatically heat the intake manifold based
on the Intake Manifold Temperature when needed prior to engine starting. Intake manifold heating improves
engine starting in cold temperatures and reduces white smoke.
“
EGT. WARNING ” Lamp - The “ EGT. WARNING ” lamp illuminates when the exhaust temperature becomes
high. These messages require timely operator attention.
