2019 LS Electronic Suspension Control Module

[ziggy1949]

I own a 2019 Tahoe LS with the towing package.
Self-leveling rear suspension has been a problem since day I bought it new.
Stopped working a few weeks ago.
I replaced the shocks and air compressor but no joy.
There are no errors showing.
I bought a new control module from Rock Auto.
Not only did it not fix the problem, but the dash shows a trailer brake error. If I put the old module back in, no errors.
The original module is stamped with part number(s):
8461 4005
8510500000000X
964992619
3119103837091161

The replacement stamped numbers are:
8461 9423
8510500000000X
116973138
3121152837819661

I cannot find a direct replacement for 8461 4005.

Has anyone had this issue and found a solution?
Any help appreciated, thanks!

sometimes the dorman modules specifically do not need to be programmed, some are either self learning or may have instructions for a procedure to do when installing such as a hvac controller
