No Bus. Truck drives but Gauges turn on and off, compass and temp blink on and off. We replaced the PCM and disconnected negative wire for hard reset, cleared the no bus code but it still comes on. Any idea is on what to do next please!?! M
No Bus means the cluster isn't communicating with the PCM. There are a LOT of possible causes for it...... Start by disconnecting rear O2 sensor, and see if the problem goes away.
does the N0Bu5 stay on even when the cluster is working? Or does it go in and out with the cluster?
The no bus code where the odometer stays on but then shuts off and reads the mileage once I'm driving for like 10 minutes it will kick back on (a/c, gauges, compass, thermometer, etc). It flickers on and off

Sounds good I will give it a shot! Do I keep it disconnected or just unplug for a little?
