## NHTSA's summary

1\) DPR System \(Diesel Particulate Regeneration\) manual regeneration may not complete; this occurs when the BCU temporally detects sticking of the CAV \(Combustion Air Valve\). This mis\-detection will cause regeneration to be suspended. In order to avoid this interruption of DPR manual regeneration, enhanced BCU \(Burner Control Unit\) software is available. 2\) Misdetection of P2030 \(Burner System Misfire\); the BCU monitors the flame temperature to confirm burner ignition occurred correctly. In some cases, a misfire may be mis\-detected if the flame is not in direct contact with the sensor. In order to prevent this mis\-detection enhanced BCU software is available.
