Rear curb slide will extend about halfway and then throws error message (room motor over current) and hard stops.  How do I tell if it’s an obstruction or a bearing that is causing the issue?

Coach 1435?  Call Newell, they are closed until Monday but have 7/24 diagnostic service.  You can get into the Valid service menu but there are too many things that can cause self inflicted problems to go it on your own.

Sorry, yes Coach 1435

Ironically, I've been fighting our P/S Rear slide for over a year. I've gone through Manual Control so many times that I now have it in my memory!!

Resisting the suggestion of replacing the motors....at $1800 ea....I continued to do the manual procedure with the hope that SOMETHING would reveal itself.

WEEEEELLLLLl....I think I can now be confident to say I've found the problem, even though some have said "probably not". THE PROBLEM WAS OUR NEW COMFORTER!!!!! It was SOOOO BULKY that, when draped and tucked around the end of the bed, it put undue pressure on that slide as it retracted!! And since I am religious with my Extend (1,2,3,4) and Retract (4,3,2,1) sequence, THAT SLIDE always comes in AFTER the D/S rear slide. (don't correct me on the stupid slide numbering thing...I hate it and NEVER get it right!!).

So, that may be YOUR cause. Now, what to do about getting your SLIDE count reset so it'll work hopefully? Here are the procedures to not only clear the error, but get the slide into alignment, and then set the Endwall Limits. These are direct from Tracy and has been vetted and re-used by myself as well as other techs.

Overrun Encoder error; can be done if slide is still extended and aligned
1. Service menu
2. CODE: 6477
3. Manual Control
4. Select Room
5. Press Vac to below 5psi
6. Endwall Control
7. No Sync Retract (Be sure fully extended and floor is down)

Set Endwall Limits; this is the usual procedure to do after an endwall/encoder fault
1. Service Menu
2. 6477
3. Manual
4. Select Room
5. Tap Vac
6. Tap Vent until below 5psi
7. Tap Endwall Control
8. No Sync Extend until Over Current error (Current should be ~8A)
9. Clear Fault
10. Change Select EW A
11. NO SYNC EXTEND HOLD until FAULT (Current should be ~8A)
12. Clear FAULT
13. Change Select EW B
14. NO SYNC EXTEND HOLD until FAULT (Current should be ~8A)
15. Clear FAULT
16. Select All
17. SET EQUAL
18. YES
19. 14500 should be on both values
20. Back
21. SYNC RETRACT HOLD until stops 0.0A (Current should be ~8A)
22. Tap INFlate
23. Hit Back to get out to OFF
24. RUN SLIDE IN AND OUT IN NORMAL/AUTO TO SAVE SETTINGS!

Nice write-up above by Steve.  Those instructions will come in handy for anyone with Valid slides.

I'm leaning more toward a failed bearing might be your problem.  I had the same issues with my slide hanging up in a certain spot and triggering the over current fault.  The slide rides on a linear bearing assembly.  If this bearing is exposed to any amount of water, the balls will rust.  The balls roll on a loop like track.  When the rusted part reaches a turn in the loop, the resistance is too much and will overload the motor.

I've replaced both a motor and bearing in one of my slides.  The motor replacement is the easier of the two.  For the bearing replacement, you will need some type of lift or support system for the slide as it must be extended to remove the bearing.  It's doable if you have a shop, the right tools, and a helper.  If that's not available, then let Newell handle it.
