## 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.
