TASC Error 4, Pump #


The TASC console displays an Error 4, Pump # message while trying to spray.


An Error 4, Pump # condition means the TASC console is receiving signals that the specified pump is turning when it should not be.


Please verify if the pump is turning when it should not be (pump switch off, no boom sections on, etc). If it is turning, remove the pump fuse and contact our service technicians for further help.

If the pump is not turning, please check the pump fuse and battery connections. A bad battery ground connection may cause this error. Contact our service technicians for more help if the problem continues.
