Bump up ntsd tolerance to about 500 and try it. Then set it back.

When those Dallas RAM chips have been the issue, it has worked for me to just swap the 2. They aren’t bad, just like glitched. Of course I don’t know if this always works.

Check and make sure your sensors are clean and dont have hoistway junk and dust. run the car down an inspection and make sure NTB goes lower case IN (menu or module ) M 2-1-3-1 i think then make sure ET1.

Only one batram chip is really used, the other is backup. You are leaving the bad one in the backup socket on the board.

If increasing your NTSD tolerance does the trick, that is a good indicator that your NTSD vane is the wrong length.
