13.0 Operator Indicators & Fault Displays
13.1 Engine & AT Diagnostic Systems
Both the engine and aftertreatment systems are fitted with a number of
sensors and actuators designed to provide tight control over engine
performance and emissions management. Each of these devices also enable
the engine management system to closely monitor the health of the system
and react as necessary when fault conditions occur.
In the event of an electronic component failure or an out of normal control
boundaries condition being raised the engine management system will react
by raising a specific indicator, fault code and in some cases take protective
action such as derate or shutdown.
The conditions under which the engine signals a system error can be defined
as fitting into one of three categories. The error category will dictate the
specific engine response and the type of indication provided to the operator.
The specific fault conditions are shown below.
Diagnostics – These conditions are related to specific electrical hardware
faults or failures such as open / short circuit conditions on sensors or wiring
loom.
Event Codes – Events are raised when the engine control system recognises
that the current system conditions are outside of some pre-defined
boundaries. Examples are coolant temperature, oil pressure and DOC intake
temperature etc.
Emissions System Inducements – These conditions are governed by
specific emissions legislation, which requires the engine manufacturer to
clearly identify specific emissions system failures to the operator outside of
the normal engine fault condition strategies.
A complete list of the available lamps for each Perkins Tier4F engine is shown
below. Mandatory indicators are highlighted where applicable.
