Bulletin Summary
This SKU is a Fuel Pump Driver Module. The customer communication requested return of unsold inventory to inspect the software. The software may have a fault where the readiness monitors are stuck in the not-ready or incomplete position. The readiness monitors will not cause performance or emissions issues but will prevent the emissions scanning tools from confirming the module is performing correctly, causing the vehicle to fail state required emissions tests.
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.
