* Note: The normal condition for the start inhibit is in its non-inhibited state. A fl oat voltage of approximately 8V (when referenced to B-) is measured
when the key is in the start position. When inhibited, the signal is pulled to ground, will read 0V and will prevent the engine from cranking. This
prevents the starter relay from being energized.
** Note: The normal condition for the run inhibit is its non-inhibited state. A fl oat voltage of approximately 10V (when referenced to B-) is measured
when the key is in the start/run and run positions. When inhibited, the signal is pulled to ground, will read 0V and will prevent the engine ECU from
receiving its needed input switch command. This prevents the ignition system from
fi ring, and if the engine is running will cause it to shut down.
Important: See the list for possible reasons the inhibit functions (start and run) could be active or inhibited.
Possible causes for start inhibit to be active causing the engine not to crank.

Drive pedal sensor switch R1 not calibrated; follow programming instructions to calibrate foot pedal sensor.

Drive pedal activated out off neutral (out of the calibrated deadband range):

Remove foot from drive pedal.

Adjust or repair the Hydroback/cable and/or drive Piston Pump linkage.

The control panel displays the critical fault icon 62E showing code #38. See the main control board fault code table code 38 TS explanation
and the engine section for engine code diagnostics.
Possible causes for run inhibit to be active causing the engine to shut down (stop running).

Loss of the engine run signal input to the main control board Pin # J1-1 (GRA):

A good LP/G (GM 1.6L) engine run signal will test 0V when measured (referenced) to B- ground. The run signal is lost when the voltage
reads 12V.

A good diesel (Kubota) engine run signal will test 12V when measured (referenced) to B- ground. The run signal is lost when the voltage
reads 0V.

The operator control panel displays the critical fault icon 62E showing code #38. See main control board fault code table code 38 TS explana-
tion and the engine section for engine code diagnostics.
