  • Advanced Automatic Crash Notification (AACN)— Provides insightful incident-related data from the vehicle, such as were there multiple points of impact; were the air bags deployed or safety belt pretensioners engaged; what was the maximum delta-v, vehicle direction upon impact and vehicle location; if the front passenger seat was occupied; and the time stamp from when the incident occurred. (Requires an active/paid OnStar Safety & Security or Assurance subscription.)
  • Diagnostic Trouble Code (DTC) Notification — Receive diagnostic trouble code information for high-severity DTCs, including information such as description and recommended corrective action. (In-Vehicle Coaching’s posted speed monitoring feature will be disabled for any vehicle whose infotainment system privacy settings are set to mask the vehicle’s location. Vehicles must have the latest software in order to maximize connected services. Software updates can be installed via Over-the-Air updates or by visiting a GM dealership.)
  • EV Charge Notification — Provides charge state information, including charge start, abort and complete. When combined with the EV data, this information offers a comprehensive EV solution for fleets.
  • Field Service Recall — Provides information regarding an open service recall on the vehicle, including the NHTSA recall number, manufacturer recall number, recall description, and safety risk description.
  • Hard Brake, Hard Acceleration & Driver Safety Belt — Reports hard braking, hard acceleration and driver safety belt information from the vehicle. The hard braking and hard acceleration events are triggered when the vehicle exceeds a predefined deceleration or acceleration threshold. Driver safety belt status is reported at ignition ON, at ignition OFF and anytime the driver safety belt status changes during the drive cycle (trip).
  • In-Vehicle Coaching — Gives fleet managers specific driving behavior event information helping promote a strong safety culture as well as verbally coaching drivers in real time through the vehicle’s audio system to help them quickly modify their behavior and develop better behind-the-wheel habits. (In-Vehicle Coaching’s posted speed monitoring feature will be disabled for any vehicle whose infotainment system privacy settings are set to mask the vehicle’s location. Vehicles must have the latest software in order to maximize connected services. Software updates can be installed via Over-the-Air updates or by visiting a GM dealership.) Driving behaviors included in this service are:
    —  Driver safety belt status
    —  Passenger safety belt status
    —  Hard brake
    —  Hard acceleration
    —  Posted speed
    —  Maximum speed
  • Pre-Delivery — Get insight into a vehicle’s location as well as its odometer, tire pressure, fuel level, and battery charge at every ignition OFF from the time the vehicle has been shipped from the plant until the vehicle is delivered to the customer and an OnStar account is created. (Once the OnStar account is created, data provided via the Pre-Delivery Data Service will no longer be available and the vehicle will need to be opted into Telemetry to receive location and other vehicle-related information.)
  • Remote Vehicle Enable and Remote Vehicle Disable — An API that allows the user to remotely enable or disable the vehicle’s engine (subject to limitations).
  • Telemetry — Provides vehicle information such as vehicle location, speed, ignition status and diagnostics from the vehicle at regular intervals. Electric vehicle (EV) equivalent info (battery level) is also available. (Location information (latitude/longitude) may not be available on vehicles equipped with infotainment systems that provide privacy capabilities that allows the driver to mask the vehicle location.)
  • Theft Alert Notification (TAN) — Provides a notification when the vehicle anti-theft system is activated. This can be either a vehicle or content theft alert. (Requires an active/paid OnStar Safety & Security or Assurance subscription. Also, vehicle must be capable to support this feature.)
  • Transactional API Calls — A single discrete request from the user to perform specific remote vehicle commands, such as lock and unlock door(s), honk horn and flash lights, and remote start and stop. Also, the user can retrieve certain vehicle information, such as vehicle location, diagnostics and electric vehicle-charge information.
  • Wi-Fi Control — Provides the ability to remotely enable or disable the Wi-Fi® Hotspot as well as view and modify the SSID and password.
