HD - Rear Diff Motor - replaced not resetting

[Philc_1974]

I recently replaced the rear diff locking motor. Had codes P0806-00 clutch position sensor circuit range/performance; p080A - clutch position is not learnt; p0810-92 Cluth position control error - component failure. And - the transmission/traction reduced warning comes on at start.

Now all were faults before the replacement. They are still there and will not clear.

I can't figure out why -

Even my local indy shop could not reset it, commenting that perhaps the module behind the battery (the one that is prone to leakage) should be replaced. But didn't say this was the answer.

Any thoughts here?

The entire diff needs to be replaced. The issue exists because the clutch packs are worn out of tolerance. I bought mine from a place in Texas for fairly cheap. Good luck.
