Lumbar Deflate Solenoid

Lumbar deflate solenoid
The lumbar deflate solenoid vents the lumbar bladder to atmosphere to allow air to evacuate the bladder. The average time to evacuate the bladder with a load of 25 kg (55 lb) is 9 seconds.

Power comes from the seat switch pack through a 3A fuse in the satellite fuse box. The lumbar deflate solenoid and the lumbar pump share an earth.
