I have a no bus on my gauge cluster the car will not crank over at all. I have change the gauge cluster in the car it had work and now again and has a no bus sign again. I drove the car and the car got up to running temperature. I turned it off went back out try to start it again and it will not start it has the no bus again on the gauge cluster. I cannot seem to figure out what is going on.

Hello there and thanks for using 2CarPros. Com. After reading a couple case study's about this issue, (seems to happen a lot on these cars), there is a PDC (power distribution center) on the left front inner fender that is connected directly to the PCM and the connector on the PDC seems to come loose because of a poorly designed hold down bolt. I would start here just looking for loose connections and wires. Make sure the PDC has a solid connections (should be a white connector with e center hold down bolt). Checking for loose wires under the dash as well, try wiggling them around and see if you can get the car started. Check wires first and get back to us. Checking PCM powers and grounds will be next.

Thank you for getting back to me on that. I will be checking those things and letting you know how my progress is going. I checked those things and it is still doing the same thing. I checked ground wires loose and loose connections under the dash still having the same problem no bus. What is the next step I can look at here? Now on my gauge cluster now I am getting an airbag a light that is coming on on the dash now with no bus. Now I have a airbag light on to now so could that be the problem?

This sounds like you have a BCM that is going out. But to be sure lets check the electrical connector for corrosion. Here is the wiring diagrams for the BUS circuit so we can see how it works and the location of the BCM connector below.

Use this guide to check the connections.

Check out the diagrams (below). Please run this test and get back to us.

Cheers, Ken
