2000 Dodge Durango code reading

Hello,

It's actually "no bus" as in no communication "bus" (a computer term for a data route). What it is saying is that the dashboard sub-computer is not communicating with the main computer (PCM) which is located on the passenger side of the engine compartment, bolted just above the wheel well area. Check the 3 connectors to see if they are plugged in all the way. If they are, your PCM is probably bad. This is something you can't replace yourself because the new one must be programmed with the milage and VIN and other info by MOPAR before it's installed. Be careful, because when the PCM fails, it will start to suddenly stall at the worst times and not restart until you disconnect the battery for 10 minutes and then reconnect.
