1. Data is reported on an event basis (triggered). Please refer to the Data description section below.

2. If vehicle model is one of the following, then data point is not guaranteed to be reported and if reported, it will be available only at the end of trip:


3. This data attribute indicates whether the location services have been disabled or masked from the vehicle. A value of -1 indicates that the location services have been disabled. A custom rule can be created to monitor location masking status. To enable the location service, please refer to this document.

4. This fault is only reported for vehicles which have active GM OnStar service ‘Automatic Crash Response’

Data Description

Accident Event

Reported if any of the below conditions is met:

  • The reported acceleration exceeds 2.6G
  • OnStar package AACR is enabled before activating Geotab service and GM detects an accident via vehicle sensors


Please note that the data is reported by calculating change of velocity as the device does not have an accelerometer sensor. Reporting logic for acceleration data:

  • Forward acceleration (Hard Acceleration): Reported only when acceleration is above 0.14G
  • Backward acceleration (Harsh Braking): Reported only when acceleration is below -0.14G

Ignition Status

  • 0 - Off
  • 1 - On
  • Reported only when the ignition state changes (event basis)

Seatbelt Status

  • 0 - Buckled
  • 1 - Unbuckled
  • Reported only when the seatbelt is buckled or unbuckled (event basis)
