Service bulletin PIC6180A

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 Preliminary Information communication provides information to the technician with diagnostic tips for auto heated and ventilated seat operation. The auto thermal seats function activates seat heating or ventilation based on outside air temperature and the cabin air temperature control error. The cabin air temperature control error is the difference between cabin air target temperature and actual cabin air temperature.
