P1698 on Dodge

On Dodge and Chrysler, the engine computer stopped receiving messages from the transmission computer on the vehicle data bus

Severity: Severity not verified — if the car runs badly, have it inspected

The sources define the code as lost communication with the transmission computer but none say how serious it is. Owners report it alongside a blank instrument cluster, so the cause could be a data bus fault rather than the transmission itself.
