I have a 1999 concorde and the odometer says "no bus" the chack engine light is on and the airbag light is on. It happens right after it is started. First the gauges drop one at a time then the odometer says no bus. anyone know anything about this? any help would be appriciated. Thanks

 

no bus is a loss of commutation with all controllers. Could be one of the computers causing this or a wire issue.

 

Where can I find the procedure to test the computer? What wiret would cause this? My scan tool came up with code p1698- no ccd message from tcm. what does that mean?
