ISX15 CM2350 ECM Replacement Help

[tree98]

Get calterm, copy file out of ecm and send it to Rawze so he can take a look at it. You don't want to tear up all your new parts. Your demandate could be the reason you had to inframe it.

When you buy the new ECM from the dealer have them bench flash it right there before you leave with it. This way if it's bad (it's not uncommon for them to be bad right out of the box) they'll know right away and you won't be stuck with a $2K paper weight because as we all know " there's NO returns on electrical parts.
Also you'll have the correct program for your truck and all the switches working so you don't have to fight that.
