Would only be able to read the current code if this set up would work,with a handset can read the fault history for the ZX and SX cards(last 16 fault codes,with battery state of charge and hr meter @ time of fault. Plus as ED T has stated you can set up and adjust with the handset.
I really should have been a bit more accurate, and said that as long as it is an ev100 LX controller or newer it will work, one from a zx truck works fine on an lx truck.
The cable that plugs into the ev100 "y" plug is the same.
and
Note that Mack's information is good as far as ev100 traction controllers, but some other GE controllers may have the stored fault codes in a different setting.
and
Off the top of my head, I seem to remember that the cost of one of those ev100 dash gages is almost as high as the handset itself, and you will still need a handset to be able to setup a new or recon card to match the truck.
If you have an ev100 handset. function 1 is where the last logged code is stored.
as long as the trucks really are the same controller
