Service bulletin SP15-07

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

Following WB13-04, update the hot gas pickup tube circuit for an improved version with a better resistance to vibrations. This bulletin resolves A/C Low Pressure messages in the dashboard when the auxiliary fan is not running. The valve will open at a set low pressure to return hot gas in the low pressure circuit until the required pressure is reached, thus preventing the occurrence of low pressure events in the above conditions.
