Air Compressor

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The compressor is a positive displacement air pump driven by a 12-volt DC permanent magnet motor. The compressor draws filtered air through an intake line attached to the chassis rail which is then run through a dryer containing a moisture-absorbing chemical that dries the air before it is sent to the air springs. The moisture is removed from the dryer during exhaust events, or when the system is depressurized. If the compressor is exposed to high thermal conditions due to excessive run time, the ASCM will command the compressor relay OFF to protect the compressors from thermal damage
