What does no bus mean on a 98 dodge stratus?

"No BUS" on a 1998 Dodge Stratus's dashboard indicates a communication problem within the car's electronic control modules (ECMs). The "BUS" refers to the Controller Area Network (CAN) bus, which is the system that allows different computer modules in the car (like the engine control module, transmission control module, airbag module, etc.) to communicate with each other.

A "No BUS" message means that this communication is failing. This can lead to a wide range of problems, including:

* Malfunctioning gauges: Speedometer, tachometer, fuel gauge, etc., may not work correctly or at all.

* Check engine light: Almost certainly will be illuminated.

* ABS and other safety system failures: Anti-lock brakes, traction control, and airbags may be affected.

* Transmission problems: The transmission may shift erratically or fail to shift at all.

* Engine problems: The engine may run poorly or not start.

The cause of the "No BUS" message can vary. It could be something relatively simple like a blown fuse or a loose connection, or something more serious like a faulty ECM or a damaged wiring harness. You'll need to have a mechanic diagnose the specific issue using a scan tool capable of reading the various modules' trouble codes. Ignoring this problem could lead to serious driving issues and safety risks.
