Reservoir, Air Suspension: Operation: Operation

WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

Because the air suspension system is a closed system an air suspension reservoir is required to store a specified volume of pressurized air for use when the system need to raise or lower the vehicle height. If an individual pressurized component of the air suspension system is damaged and air pressure is lost, the reservoir will hold any pressure left in the component when a scan tool is used to evacuate the component. After repair or replacement of the component a scan tool can be used to refill the component from the reservoir.

The compressor cannot refill the reservoir and complete system if all pressure is exhausted as in a compressor assembly or valve block replacement. The system will need to be filled at the reservoir using shop air. For filling the reservoir after a repair. Refer to AIR SUSPENSION, STANDARD PROCEDURE .
