Hello and welcome to just answer. A "no BUS" message means that the PCM (engine computer) has failed, a PCM fuse is blown, or that the cam or crankshaft position sensor has shorted out. Do this: check and replace any blown fuses you see in the under hood or inside fuse boxes. If they are ok, then remove the engine cover and disconnect the cam sensor at the distributor, and the crank sensor at the top right area of the transmission bell housing. See if the "No Bus" message goes away. If it does, then replace the appropriate sensor. If it still shows No Bus, then suspect a failed PCM and have it replaced. I hope this helps, Chris
