you actually are supposed to have 45 Ohms on the local channel. Channel 1 is local, 2 and 3 are hw and car that should have 60 Ohms. Configuration matters too, not just the resistance (i.e. under 30' = no termination, star patterns etc) 2.5vdc is correct on your channels.

This looks like a while ago but if still not solved try/look for a couple of different things. The brake system, believe it or not is pretty susceptible to noise and will cause a 1508 fault. A lot of times, because of the voltage required for the coils most folks don't run them separate from all the other runs to the machine. A comm loss on the drive is pretty common depending on if you have a 10K drive, DSD, or an Accord.


I would start with 2407MC for sure, but you may check the jumper config on the CPUA as well. If you have 60 ohms on the CPUA comm channel (local channel) then they are probably in the wrong config.
