Service bulletin AA0F0

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

ECU Diesel Particulate Reduction (DPR) Enhancement DPR Clogging may occur due to an increase in the amount of soot in the exhaust gas as a result of engine component degradation. In order to reduce the soot in the exhaust gas during this situation, even when the engine components are degraded, enhanced ECU software is available.
