Explore OnStar^® API & Data Services

From crash notifications* to vehicle diagnostics* our providers can give you the info you need to help keep your fleet and drivers on track. Their data services include:

Advanced Automatic Crash Notification (AACN)

Provides insightful incident-related data from the vehicle, such as there are 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.*

Diagnostic Trouble Code (DTC) Notification

Receive diagnostic trouble code information for high-severity DTCs, including information such as description and recommended corrective action.

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.

Hard Brake, Hard Acceleration and 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, which helps to promote a strong safety culture. Drivers are verbally coached in near real time through the vehicle's audio system so that they can quickly modify their behavior and develop better behind-the-wheel habits.*

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

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 information — including vehicle location, speed, ignition status and diagnostics — from the vehicle at regular intervals. Electric vehicle equivalent info (battery level) is also available.*

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.*

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.
