GP400 Module
The GP400 module is “the brains” of the system. It receives and processes a variety of inputs both
from the machine and the operator, then controls all the operative functions of the machine. It also
has a feature that allows the technician to access and monitor all functionality of the system, along
with a technician-friendly series of fault messages that can be accessed through the use of the
onboard EZ-Cal scan tool. Flash codes are also provided in case an EZ-Cal scan tool is not available.
Such information can be used for preventative maintenance and troubleshooting should a problem
arise. A comprehensive list of EZ-Cal accessible information can be found later in this section.
The GP400 operates on 12 volts DC and should never be probed or operated with voltage higher
than 14 volts DC.
