Control Module

The rear air suspension/EVO control module services both the rear air suspension system and the Electronic Variable Orifice (EVO) steering system. Two connectors at control module are keyed to prevent incorrect connection. The control module continuously monitors rear suspension through a preprogrammed sequence. The system operates with the ignition switch in ON position and with limited operation for one hour after ignition is turned off.

The control module controls the compressor relay and vent solenoid. The control module also controls power and ground to height sensor. An averaging interval of 45 seconds is incorporated into the control module to eliminate unnecessary suspension corrections. This interval prevents small bumps or road surface variations from causing constant, unneeded suspension adjustments.
