Examples include setting alarms, door locking, improving driving performance and fuel efficiency, and disabling automatic engine start/stop.
- Bi-directional Control (Actuation Test): The tool can actuate solenoids and actuators to perform active tests, sending commands to various systems/components to check their operational status without needing to use the vehicle's controls. This includes testing components like the fuel pump, radiator fan, modulating the throttle, operating windows and mirrors, turning on interior/exterior lights, sounding the horn, and testing door lock actuators.
- FCA Auto Auth: For 2018 and newer FCA vehicles (Chrysler, Dodge, Jeep, Fiat) in the US, Canada, and Mexico, the DS300 supports FCA Auto Auth for free.
