Service campaign N262559000-01

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

Certain vehicles may have a condition in which the software that maintains the RESS battery pack may inadvertently cause a drain on the high voltage and low voltage batteries. Dealers are to program the Battery Energy Control Module then fully charge the high voltage battery to reset the cell balancing software.

The document
