You may need a new flasher relay, there pretty cheap to repace, its usally in the fuse box, a round colerd thing, usally yellow or silver metal that plugs in. There a little bigger then a soda bottle cap. Sometimes even one blow out bulb can keep it from working so make sure all your bulbs are good.
Check fuses and the headlight switch.
The odometer has failed.
Start with checking the fuses.
Blown fuse, defective fuel pump relay, or defective fuel pump.
On a 2000 Dodge Ram, "no bus" means the communication network between modules has quit working. Any module on the network or the wiring between them can be the cause of the malfunction.
the flashers in the 1995 - 2500 ram van are located behind the glove box - have to remove inside of glove box to see them.
i just changed the speed sensor on my 91 and it took care of that same problem.
Fuse blown?
Possible causes include broken wire, failed switch, blown fuse, faulty flasher.
Make sure that the amp is grounded.
