Spray System Fault − flow meter not working correctly or

harness fault (No flow detected when based upon boom, pump

and pressure it indicates there should be)

Spray pump is ON,Master Boom switch is ON, at least one

boom is ON, spray pressure is above 20 PSI, the booms have

been on long enough for the system to stabilize and vehicle

speed is fast enough for automatic application−rate control to

be enabled

Check the flow meter harness

for proper connection.

Confirm fluid flow at spray

nozzles. If so, flow should be

displayed on the flow rate me-

ter. If no fluid flow at spray

nozzles, begin checking the

spray system for a blockage.

Check flow meter for proper

function.

41 Spray System Fault − Controller has detected a short circuit on

the spray pump PWM output circuit (TEC output 9 − pin 44).

Controller has determined an internal component in the

controller has overheated.

Check harness and associat-

ed components for a short to

ground

If fault persists, replace TEC

due to internal damage. Con-
