Even though these fault codes are T (traction) faults they are actually steer faults, traction is shutting down for safety reasons due to a fault detected on the steering system.

Do you have working hydraulics?

First thing is to check the 50 amp fuse under the arm rest. A hairline fracture will allow the steer system to activate and not cause a fault code but when the traction system puts it under load it fails.

Try this and if the fault continues I can send you some information about faults in the wiring loom that are quite common, other than that it may be a faulty steer sensor or lord unit.
