PTO Remote Fender Switch Open
Cause:
The Data Bus signaled that a PTO remote fender switch is stuck open. The PTO remote switches are hard wired to
the AUX/Hitch/PTO controller.
NOTE: AUX/Hitch/PTO fault code 159 may also be recorded.
Possible failure modes:
1. Bad remote PTO switch.
2. Software execution error in the armrest controller (small chance).
Solution:
1. Check the wiring from the AUX/Hitch/PTO controller connector C057 back to remote fender switches. Check for
damage, chaffed wires that could result in an open circuit.
2. Disconnect AUX/Hitch/PTO controller connector C057. Ignition switch ON, check for power at connector C057
pin 12 to ground. The voltage should read approximately 12 volts. If 12 volts is not present check both remote
PTO fender switches. Both switches are normally closed. Replace the switch that is open.
