Bulletin Summary
29400 Special Coverage. Certain vehicles that are equipped with a diesel engine (RPO LML/LGH/LUZ), a malfunction-indicator light (MIL) may illuminate due to an offset in the temperature sensor in the diesel-emission-reduction fluid (DEF) tank reservoir or increased DEF tank-heater resistance. Dealers are to replace the DEF tank reservoir. The repairs will be made at no charge to the customer.
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.
