Figure 4.2.1: Schematic for basic
‘inside’ PTO operation using control relay and oil solenoid
as
well as optional outside
‘remote’ operation [start/stop, tap
up/down]
NOTE: The PTO connector X191 has a cap installed at the assembly plant with a
jumper between pins A and J. The cap is a useable mating connector and it could
be rewired as shown above. To avoid setting internal trouble codes the continuity
between connector cavities A and J must be constantly maintained except during kill
switch actuation for MY2015-17. MY2018 and beyond the jumper is only required
for remote operation if arm and kill switches are not configured.
