indicator lights will be illuminated for 2 seconds after
the keyswitch is operated. Replace suspect bulbs
immediately.

Overspeed
• ECM
Electronic Control Module
• RPM
Revolutions Per Minute
An overspeed is detected by the speed/timing
sensors.
The default setting for an overspeed is 3000 rpm.
The ECM will cut the power to the electronic unit
injectors, until the rpm drops below 200 rpm of the
overspeed setting. A diagnostic fault code will be
logged into the ECM memory and a warning lamp will
indicate a diagnostic fault code.
An overspeed can be set from 2600 rpm to 3000 rpm.
This setting depends on the application.
