Aux/Hitch/Pto Fault Code 7 - New Holland T8010 Manual

Hitch Raise/Lower Solenoids Circuit Failed Open, Or Short To Ground
Possible failure mode:
1. Wiring problem from the hitch controller to the solenoids.
2. Both raise and lower solenoids failed.
Solution:
The chance for both raise and lower solenoids to fail at the same time is rare. If fault code hitch 4 exists, check the
single solenoid resistance and its wiring harness. If no other code exists, check the hitch valve wiring.
1. Check for fault code 4. If it exists, follow its corresponding diagnosing procedures.
2. If fault code 4 does not show up. Check the wiring harness from connector C058 and C053 to C151 for an open
circuit or short to ground.
NOTE: Always inspect connector ends for damaged, bent or dislocated pins when troubleshooting.
NOTE: If the problem is intermittent, it may be caused by temperature change on a progressively deteriorating
controller. Some shortages are intermittent at initial stage.
NOTE: See schematic sections 51 and 52 on the schematic poster.
