Circuit Description
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The air suspension compressor 2 has a temperature sensor. The overtemperature sensor is a thermal limit switch that is in the normally closed position. This provides a ground signal to the air suspension module. The air suspension module monitors the temperature sensor for a compressor overtemperature condition. On receipt of a compressor overtemperature condition the air suspension module switches off the compressor relay. The relay cannot be switched on again until at least 3 minutes after removal of the overtemperature condition.
