it's also a real possibility that you have the wrong eeprom installed in the logics. does the number on the new eeprom on the new logics match the number on the old eeprom on the old logics? the eeprom PN (and related programming) are different for different options on the truck so if the logics has an eeprom for a contactor type hydraulics and the truck is a chopper type hydraulics, or a different voltage, you will get an error about like this.
