ABS, ASC, Handbrake, Airbag lights lit on dash, speedometer now working and fuel gauge playing silly beggars too

The abs,Asc,Handbrake all this is related to most likely a sensor that has gone out is not functioning properly. I would not drive this myself, especially with the air bag light on as if computer is throwing these signals out, you do not want to take the chance of air bag accidentally going off. Most this I am sure can be fixed at dealer. They will hook up there fancy equipment diagnostic machine, and reset the computer. Worst case is there might be a sensor that has to be replaced. This could be also a short in wire harness. Bottom line take it in and have them hook up to machine. This will pin point problem, because next step would be car could automatically shut down.
