FAULTS
When a fault occurs, the trowel's horn will begin a repeating
cycle of 5 beeps every 30 seconds. The amber LEDs on
the diagnostic display will turn ON (Figure 57), and the
Check Engine icon will be shown on the display. When
this happens:
1. Press the button on the right side of the display to view
the active fault code (Figure 58).

repeat while the engines are running or the ignition key is
in the ON position.
