Code P1698 on a 2002 Dodge Neon indicates a problem with the communication between the Engine Control Module (ECM) and the Transmission Control Module (TCM). This may result from issues such as wiring problems, a faulty TCM, or a malfunctioning ECM. It's essential to check the connections and wiring for damage and consider testing or replacing the TCM if necessary. Addressing this issue can help restore proper communication and functionality between the vehicle's systems.
