My truck has "no bus"lighting up.The truck cranks but the gauges,lights,blinkers,wipers dont work.Someone told me it was the ignition switch so i changed it but it didnt fix anything.The truck is a 2003 model.

I don't know if this will work, but it worth a shot. Check the IOD fuse.

More than likely one of the modules is kaput and locking up the bus system. It could be ABS, AIR BAG, ECM, PCM, FCM, BCM? You can unhook the modules one at a time and see if the message goes away. Other than that, you need a scanner to diagnose more.
