Bulletin Summary
The Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have approved an emergency calibration to provide temporary relief from the global supply shortage of electrical components. When there is a communication fault in the DEF head unit / Quality Level Sensor (QLS) this temporary calibration will allow the vehicle to operate. The procedure in this document will include diagnosing the DEF head unit / QLS and if found to be defective will advise to install the temporary engine calibration if replacement parts are not available. Any vehicle that receives this calibration will be required to have it removed and a new QLS installed once parts become available, this will be managed through future communication.
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.
