Bulletin Summary
This bulletin provides instructions for installing an updated park brake valve pressure switch to eliminate the "sticking" switch issues, as well as the unintended horn alarm when the cab door is open. The updated pressure switch has a higher pressure activation and reset values which reduces the delay experienced with the previous pressure switch.
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.
