Troubleshooting
Steering Flash Error Codes
Steering
reversed
Sensor installed on incorrect tractor side
or incorrect location on axle
Reinstall sensor at location specified in Pre-Delivery manual
401-647Q.
ST1 and ST2 connections reversed at
manifold valve
Check entire hydraulic system against diagrams in Parts manual.
Correct connections as necessary. If the mis-connection was not
the result of local maintenance, report problem to dealer or Great
Plains.
Hoses to steering cylinders reversed at
left cylinder
Check entire hydraulic system against diagrams in Parts manual.
Correct connections as necessary. If the mis-connection was not
the result of local maintenance, report problem to dealer or Great
Plains.
Harness connections reversed at valve
coils
Swap connections at ST1 and ST2. If the mis-connection was not
the result of local maintenance, report problem to dealer or Great
Plains.
