Anybody seen this before? Dash lights up like a Christmas tree. Check engine, ABS, air bag, low fuel, check guages, brake, etc. lights all come on, all guages drop to 0, mileage odometer disappears and and in it's place a message, "No Bus" comes up. I know it's a communication problem of some sort but was just wondering if this is a common problem that somone else has seen and fixed or if I have a lot of diagnosis ahead of me. Thanks.

 

mine did that when i forgot to put on the 2-3 ground wires at the power steering pump. there are also a group of grounds behind drivers side kickpanel. maybe some on firewall near pcm. also clean the ground cable at battery. i've also heard of it doing this with a blown fuse (check end of dash and pdc box under hood). also check that all wires and plugs are tight at pcm.

 

had a problem like that with my dakota a while back an it was a lose ground behind the cluster cause when it happend i could smakc the top of the dash an it would come on,so i checked an fixed it
