Codes after installing REVELL links

[CdnHO]

I installed Revell links on the rear of my 3500. About an inch shorter than stock in order to lower the back end some when towing the fifth wheel. Nothing showed on the dash after the install. For the heck of it, I did a obd scan with my Blue Driver and received the following messages:

C1526 Left Rear Ride Height Sensor Circuit: Signal Amplitude Below Minimum
C152A Right Rear Ride Height Sensor Circuit: Signal Amplitude Below Minimum

Basically shortening the rods make the computer think the truck is higher than it actually is.

Any insight appreciated

when not loaded my air bags are soft so its riding on the springs not the bags so it can't lower anymore when not loaded.

The truck isn't any lower unloaded as it is sitting on the springs, but the end of the sensor arm is lower which I assume is causing the code. Will be putting 5K of pin weight on the hitch on Sunday. Will be interesting to see what the truck thinks of that.

Hook up with 5K pin load. Alternate trailer height enabled with no issues.
