As soon as an engine fault is detected, it is evaluated and one of the following
measures is initiated.
In conjunction with any dashboard or instrument panel display, the code for the
electronic control unit reporting the fault can be read immediately on the display.
If the fault is serious enough to impair normal operation, the electronic control
unit switches over to a "limp home" mode. The limp home speed is dependent on
engine control parameters and could be as low as 1000 rpm. This allows you to
safely move the vehicle to a service location or a safe stopping area.
Stop Engine Override Option
The Stop Engine Override Option is used for a momentary override. The electronic
engine control system will record the number of times the override is activated after
an engine fault occurs.
Momentary Override
A Stop Engine Override Switch is used to override the shutdown sequence. This
override resets the 60 second (30 second for oil pressure) shutdown timer, restoring
power to the level when the RSL/Stop Engine was illuminated. The switch must be
recycled after five seconds to obtain a subsequent override.
NOTE: The operator has the responsibility to take action to avoid engine
damage.
