IMPORTANT: Set main pump controller to
“OFF” while servicing engine. Before turning the
main pump controller to the "OFF" position,
check with the maintenance and security
supervisors to verify that all the departments
concerned will be alerted of the temporary
interruption of their fire protection equipment for
normal maintenance or testing. Also, alert the
local fire department if the main pump controller
is connected by silent alarm to headquarters.
When servicing is complete, return main pump
controller selector to "Automatic" position and
the mode selector on the engine to “Automatic”
position. Advise the appropriate personnel the
engine has been returned to “Automatic”.
5.0 TROUBLE SHOOTING
General Troubleshooting Information
Troubleshooting engine problems can be difficult.
The engine control unit (ECM) can detect problems
internally and in the electronic control system. This
includes determining if any of the sensor input
voltages are too high or too low, if the camshaft and
crankshaft position sensor inputs are valid, and if the
unit injector solenoids are responding properly.
If the ECM detects a problem with the electronic
control system a diagnostic trouble code (DTC)
specific to the failed system will be stored in the
ECM’s memory.
5.1 DIAGNOSTIC TROUBLE CODES (DTC’s)
There are two types of DTC’s
 Active
 Inactive (stored)
Active DTCs indicate that the failure is occurring.
These types of failures are sometimes called “hard”
failures. They can be accessed on the diagnostic
gauge (A) on the instrument panel.
Inactive DTCs indicate that a failure has occurred in
the past, but is not currently occurring. This type of
“stored” DTC can be caused by an “intermittent”
failure. These could be problems such as a bad
connection or a wire intermittently shorting out.
If a sensor or wiring fails and a DTC is active for the
sensor, the ECM will use a substitute “limp home”
value in its calculation to continue engine operation.
Displaying of Diagnostic Trouble Codes (DTCs)
SPN/FMI CODES
Stored and active diagnostic trouble codes
are output on the PowerView Gauge
according to the J1939 standard as a two-
part code as shown on the table on the
following pages.
The first part is a Suspect Parameter Number
(SPN) followed by a Failure Mode Identifier
