When bobcat is turned on, I immediately get "no communication to bobcat controller" and "no communication from drive controller". I am also getting a variety of codes: 39-13, 40-13, 39-16, 40-16 are the most common. Any suggestions about where I should start? Have checked all fuses and they are fine.
No replies so let me post what we did to fix it. We removed the ACS controller and the Drive Controller and reseated the electrical connections. After reinstalling the ACS controller we also re verified that the connector latches were still latched (they tended to unlatch while we were positioning it for reinstallation). Noted that one of the pins on one of the ACS connectors was slightly pushed so we repositioned it. Also cleaned and put dielectric grease on all connectors. When we restarted the machine we immediately regained loader control and half the fault codes were gone. Several minutes later we restarted the machine and all fault codes were gone. Machine was fully operational. It was the first time working on one of these for our three person team so it was interesting to say the least.
Good job!
in the future disconnect all connectors in cluding the computer ones, clean them with cleaner and spray them with Deoxit Gold.
