Aux/Hitch/Pto Fault Code 23 - New Holland T8010 Manual

Both Draft Pins Failed
Cause:
Both draft pins failed when tractor is configured for two draft pins.
Possible failure modes:
1. Draft pin failure.
2. Wiring problem.
If the problem is intermittent, the draft function is disabled until the next engine start up.
Solution:
The chance for both draft pins to fail at the same time is rare. If fault code hitch 30 or hitch 31 exists, check the
single pin function or its wiring. If none of the codes exists, check the power supply or the ground to the two pins.
1. Check for the single pin fault code hitch 30 or hitch 31. If any exists, follow its corresponding diagnosing
procedures.
2. If none of hitch 30 or hitch 31 exists, check the power supply or the ground to the two pins.
a) Check the power supply at either left pin connector or right pin connector. There should be +8 volts at cavity
C of C153 or cavity C of C154.
If not, check the continuity from connector C057 pin 25 to the cavity C of the right draft pin connector and from
connector C057 pin 31 to the cavity C of the left draft pin connector
b) Check the ground to the two pins. There should be continuity between cavity A of either left pin connector or
right pin connector and the cavity 23 of C053.
If not, check the wiring in between.
3. If none of above, check the function of the hitch controller.
NOTE: Always inspect connector ends for damaged, bent or dislocated pins when troubleshooting.
NOTE: See schematic sections 51 and 52 at the rear of this section.
