Function 

When the RHR unlocking switch (S6/1s3) is actuated the extended rear head restraints are retracted.

Function sequence 

The switch signal from the RHR unlocking switch (S6/1s3) is read in by the signal acquisition and actuation module (SAM), (N10/1) and sent to the PSE control module (combined) (A37) as a CAN message "retract rear head restraints". The PSE control module (A37) actuates the RHR release valve (Y24/1) pneumatically.
