"No BUS" on a Dodge dashboard indicates a
communication problem within the vehicle's electronic systems. The "BUS" refers to the Controller Area Network (CAN) bus, which is a digital communication system that allows different electronic control units (ECUs) in the car to talk to each other. When this communication is interrupted, the "No BUS" message appears.
This is a serious issue, as many crucial functions rely on the CAN bus, including the engine, transmission, airbags, and various sensors. It needs to be diagnosed and repaired by a qualified mechanic as soon as possible. The cause could range from a faulty sensor or ECU to a wiring problem.
