FRONT AND REAR AIR SPRINGS The front and rear air springs are essentially pneu- matic cylinders that replace the steel coil springs. The air springs allow for the reduction of spring rates to improve vehicle ride characteristics. FRONT/REAR SPRING SOLENOIDS The front and rear solenoids control air flow in and out of the front and rear springs. The Air Suspension HEIGHT SENSOR A magnetic switch type sensor. Located in the right rear shock absorber and left and right front CONTROL MODULE The Air Suspension Control Module (ASCM). Is a device that controls the ground circuits for the Com- vent damage to the compressor motor. To prevent excessive cycling between the compres- sor and the exhaust solenoid circuits during normal The system is non-operation when one of the fol- lowing conditions exists. A door(s) is/are open, the COMPRESSOR ASSEMBLY The compressor assembly is driven by an electric motor and supplies air pressure between 930 to 1241 A heat actuated circuit breaker. Located inside the compressor motor housing. Is used to prevent damage COMPRESSOR AIR DRYER The air dryer is attached to the compressor (Fig. 3). This component serves two purposes. It absorbs mois- Fig. 2 Front and Rear Air Springs 2 - 74 SUSPENSION AND DRIVESHAFTS Ä |
