I have a truck with a 2F code, re-gen curiuit failure. I fallowed the trouble shooting guide all the way to replacing the cards. when I replaced the cards (one at a time) nothing changed. I now have the card from the "broken" truck driving my customers other truck with no problem at all. any ideas at all as to what else it could be? or what other componets are in the curcuit that may not be listed in the manual?
thanks in advance
