The "No Bus" error message on a 2001 Dodge Ram typically indicates a communication failure between the vehicle's onboard computer (ECU) and other critical systems or modules. This can result from a faulty connection, damaged wiring, or a malfunctioning ECU. Essentially, the vehicle's diagnostic system is unable to communicate properly, which can affect various functions and performance. It's advisable to check the wiring and connections, as well as consider scanning for additional trouble codes for a more accurate diagnosis.
