Chrysler Repair: 2004 sebring: no bus message on cluster, 4 digit numbers, digital signals

Question
The engine won't try to turn over and a message on the dash says no bus or bu5. I just parked it and it was running fine 10 minutes ago.

Answer
Hi Tina,
'No bus' is a very general code that means for some reason the inter-communication, between some module of a system of several modules that communicate data between each other over a pair of wires (the 'bus') using digital signals, is not getting shared properly. The only way to narrow down the cause is to plug in a 'code reader' at a socket under the dash just to the left of the steering wheel and request a more complete fault code (a four-digit number) that would tell specifically where/why in that data sharing network the problem has occured. The computer that operates the engine is part of the system and that is probably why it won't start.
If you know a mechanic with such a code reader who would go to the vehicle with a reader to retrieve the fault code, that would be one way to start. Or tow the car to such a mechanic. If by any chance it would start and run you can often get a free readout at an Autozone Parts store. Most independent shops will do a readout for under $40. Parts stores sell readers but they cost in the range of $100-200. You might try turning the ignition key:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time, and see if some other number or words appear in the window of the dash where you saw "no bus". Write back with any such 4-digit numbers.
