Bulletin Summary
Freightliner Service Bulletin for Detroit Assurance 4.0 Software v20.05. 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
