Normal Operation

When venting of the rear air suspension system is necessary, the air suspension module sends voltage to the vent solenoid along circuit 421 (PK). This voltage engages the solenoid which then vents the system. The solenoid is provided a ground along circuit 57 (BK). The vent solenoid is part of the air suspension compressor assembly and is serviced as such.
