Overspeed
• ECM Electronic Control Module
• RPM Revolutions Per Minute
An overspeed is detected by the speed/timing
sensors.
The default overspeed is set at 2800. The ECM will
cut the power to the electronic unit injectors, until the
rpm drops below the overspeed setting. A diagnostic
fault code will be logged into the ECM memory and a
warning lamp will indicate a diagnostic fault code.
Some application may have a display panel in order
to alert the operator.
