System and Method for Deciphering and Mapping Signals from an Electronic Control Unit for use in Occupant Safety

A system and method for deciphering signals and messages from a control unit, and mapping those signals to the associated sensors to create a map of the sensor status. The map of the sensor status is then used in conjunction with a dongle and software application to interface with the control unit, able to receive messages from the control unit to monitor the status of the sensors, and to send messages to the control unit to manipulate the sensors. The system and method can further be used to interface with the electronic control unit of a vehicle to detect unattended access of the vehicle and ensure no passengers are left abandoned in the vehicle, such as by sending alerts to a mobile device of the user, triggering alarms in the vehicle, or sending alerts to emergency services.
