Service bulletin TSB210053-030320

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.

NHTSA's summary

This Technical Service Bulletin describes the verification and resolution of Fault Code 286, which will activate at each key ON for a few seconds before going inactive. Fault code 286 will clear with the recommended Cummins® electronic service tool or equivalent but will come back once the bus is keyed ON again.
