No buS

[Emptypockets]

Hopefully Brandon is MIA until I get the answer I need

I have a 2000 Dodge Ram 1500 and my odemeter is reading No buS I have looked over the internet and it seems to be a common problem but haven't really found the right answer as to what causes it. Non of my my gauges work including my speedometer or my tack. I have heard that it is the cpu and heard that it is the dash cluster needing to be changed, so I am trying to find out if anyone here really knows the answer so I don't change parts that I don't need to

Thanks for your help

You might be best to just take it to a Dodge dealer.Sometimes - there are silent recalls, the dealer fixes it for free but they do not notify everyone.Case by case deal.

I had a 1991 Ford F-350 and lost the tach after about 9 months.The mechanic told me it was a fibble switch - I honestly thought he was teasing me.Well, there is such a thing as a fibble switch and it was the problem.

You getting a no buS - sounds like electrical problem.Hopefully something simple.I've heard of road salt getting into a connector that was not tight and causing trouble.

Just a guess, Go check your revers lights mabye buS stands for back-up switch. If that turns out to be the problem just send me the $59.99 I charge for my internet mechanic fee.

I think it's a computer issue like you mentioned dash not communicating properly with the computer. Could be a simple as a loose connection somewhere or a computer going bad. Obviously go with checking all of the connections first.

Buss is the line the moduels trade information on. Most likely dash cluster, ecm or bad ground

Not sure how in depth a scan you can us the scanner for free @ Advanced Auto (On Allpar there is combo of turing the car on and off the the # Code)

To find the codes on a dodge you put the car in park turn the ignition awitch on (not to start) and off three times. The code will flash up on your check engine light normally three digits, you can look them up online. It will blink the first number pause and then the second pause, then the third. Hope this helps.

Codes are not going to help you.. Most likely ground pcm or cluster. You can disconnect battery wait a min and reconnect and it will work again but will happen again in time.
Good luck

You know ........ just google it on the internet ........ I just did and here is just one of the responses .......... Does anyone know what "no bus" means, my car won't start... - Q&A

Means the CPU is not communicating with the gauges

What does an indicator saying "no bus" mean on a 2008 charger dash? - Yahoo! Answers

[chocomilo]

Is possible one of the modules could set a no comunication code. I did look it up on Identifix an online progam we use at my auto shop and there are alot of shops that replaced the ecm or IC for the same problem. Probably 10 or so. Best thing would be hook up a scanner and see wich modules are comunicating on the bus and which are not. I dont know much But I did work for a chrysler dealer as a tech from 1989-2004.
