    Reported if any of the below conditions is met:

1. The reported acceleration exceeds 2.6G
2. OnStar package AACR is enabled before activating Geotab service and GM detects an accident via vehicle sensors. In this case, the event is reported as Fault 166. This could be included as a trigger condition in the ‘Possible Collision’ rule to improve accuracy.
