Bulletin Summary
Western Star Service Bulletin for Ordering Options for Aftermarket Power Distribution Modules (PDMs). For certain Western Star 4700 or 5700 vehicles, power distribution modules (PDMs) are typically ordered in the aftermarket by serial number and populated with fuses and circuit breakers. It may take up to three weeks for a serial number specific PDM to be processed, made, and shipped to a dealership. In order to reduce the down time of a vehicle, an alternative PDM may be ordered fully populated with fuses and circuit breakers and delivered the next day. A cost increase may be associated with this option.
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.
