Jeep Tj No Bus. The Jeep would not go from the run position to the off position and the radio would not come on at all. The Crankshaft Position Sensor (CPS) is the most common failure, ( and the symptoms.
The benefits include: A code read at the odometer NO BUS - My oil light and engine light came on. I have the tj giving me hell the dash says 'no bus' and the air bag light is on which I just discovered last night that the bulb in the back of the cluster was missing so replaced the bulb and plugged gauges back in started the jeep and it was on immediately, also a few seconds after start up along with the 'no bus', air bag light, the check engine light comes on. It has the tsb connector repair.
The Jeep would not start and it had a constant high pitch tone on the driver side of the engine bay.
I've used alot of the flow charts through alldata.
I do have a weirder part. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. The "no bus" message you saw was probably the dash saying, "hey I can't talk to the network".
