Engine monitoring system
WARNING
Risk of accident
Modifications
made to the electronic system or to the wiring of the vehicle could cause an accident
and severe injuries.
► Always have any work or modifications to electronic components carried out by an authorised
service centre.
The engine is equipped with a comprehensive programmable engine monitoring system. The engine
control
unit monitors the operating statuses of the engine. If the value of one of the engine parameters
leaves its permissible range, the engine control module responds immediately.
It will respond in one of three ways:
■ Emit a warning message
■ Reduce the power
■ Shut down the engine
In many instances, the response actions can limit the engine speed and/or restrict power output.
Many of the parameters are monitored by the control unit.
The engine monitoring system keeps track of the following parameters:
■ Altitude at which the engine is operated
■ Coolant level
■ Coolant temperature
■ Engine oil pressure
■ Engine RPM
■ Fuel temperature
■ Air temperature in the intake manifold
■ System voltage
The version of the engine monitoring system can vary with the engine model and engine configuration.
However, the monitoring system and engine control unit are similar for all engines.
