Reservoir, Air Suspension: Operation

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The air suspension system is an open system. The air suspension reservoir stores a specified volume of pressurized air for use when the air suspension system needs to raise the vehicle height. If a single component is damaged, the reservoir will hold any pressure left in the component. 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 with nitrogen. For complete filling of the air suspension system after a repair. Refer to STANDARD PROCEDURE .
