Service bulletin PIC6131

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 about vehicles that the air conditioner blows warm air. If normal diagnostics from service information does not lead to a correction and it is found that the air conditioning compressor is not engaging check for any communication codes in the vehicle and address them first. It has been found in some cases that there is no communication with the sensing and diagnostic module that was causing the air conditioning compressor to not engage.
