How does my NH T6 know when the wheels are straight?

To allow the diff lock to engage?

My auto diff lock switches on, but never engages. The manual diff lock doesn't switch on.

Presume a sensor faultt?

The auto 4wd and diff lock works off the wheel angle sensor located in the right hand kingpin. It turns on and off at certain degrees (this can be altered by dealer laptop to give a wider or narrower range if needed)
If your diff lock isn't working in manual mode it could be a sensor fault possibly located on the front axle in the middle. Could be a switch fault also. Have you checked for any fuses

There are no fuses for the diff lock. Not in the fuse box in the cab anyway.

I did notice a second fault today though,
Full clutching and braking is occurring when just the left brake is pressed. Just pressing the right one just works the right brake as per normal.

Possibly unrelated faults?

Thats what i mean, does the tractor have a brake to clutch feature

Yes it does.

 

[S.Jamieson]

But it should only work when both brake pedals pressed, not just one?
