General Information
New Cascadia trucks built from January 1, 2017 through September 9, 2019 and equipped with Detroit
Assurance correctly initiate an active brake assist (ABA) event when a vehicle or obstacle is detected in front of
the truck. Some of those trucks may continue decelerating to a complete stop, even after the vehicle or obstacle
detected in front of the Detroit Assurance-equipped truck has moved away. If a customer describes this series
of events, the truck can be updated to Detroit Assurance 4.0. This procedure is performed using
DiagnosticLink®.
Changes in Detroit Assurance 4.0 Software, v20.05
Detroit Assurance 4.0 software v20.05 modifies the ABA behavior. If the vehicle triggering the ABA event is no
longer detected in front of the truck, the ABA event is immediately cancelled, even if the truck has not come to a
complete stop.
