Gen2 learn

I was trying a learn run on a gen2 and I get a ntb len error at the bottom. Tool says to add 0746 (mm) to the length of vane. If this is a parameter change I can’t find it anywhere on the tool. If it’s telling me I need to make the length of the vane that rides with the car physically longer than why was the elev ever able to do a learn run in the first place?

Jump out your normal limits while doing learn run

It is telling you that the NTB vane length is incorrect. When entering the learn it will tell you estimated vane length for NTT and NTB and is dependent on Accel/Decel rate. If NTB signal is lost to early it reports the difference (746mm). Possibly the accel/decel rate parameter changed or you are losing NTB signal to early.

It turned out to be bad leveling sensors causing the issue
