Bulletin Summary
The battery box located directly under the driver's side doorsteps of the cab is equipped with a 50A fuse and fuse holder that is connected directly to the battery for constant power. This fuse powers a 70A relay that is used for the safety systems of the truck and is located on the right rear side of the battery box. Due to the fitment of the battery box lid from the chassis manufacturers, moisture and debris are able to fall through the space between the battery box lid and side of the battery box body. This may lead to corrosion of the fuse and holder, which may result in failure of the fuse, loss of current flow, and ultimately the inability to operate the truck. This quality issue affects Kenworth T380 and Peterbilt 537 chassis on Jarco propane bobtail units produced from January 2023 until January 2024.
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.
