On the way to work today, all of my gages quit working and all my warning lights came on. The odometer is displaying the code "No Bus".
Any idea what this could be?

 

Loose/dirty connection

 

where ?

 

Mine did it after coming out of the car wash. I let dry out and everying came back. It's never did it since, im sure i just got some water in one of connections.

 

Had the same problem but mine was water in the bus connection under the dash. Root cause was that I poked a hole in the bulkhead diaphram for my gauges and water ran down the lines through the bulkhead and right to my connector. Make a tape dam and the problem
seems to be solved.
