Air Springs

WARNING: This page is about a different car, the 2014 RAM 3500 HD and 2014 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

All pressurized air suspension components contain high pressure air (up to 220 psig). Use extreme caution when inspecting for leaks. Wear safety goggles and adequate protective clothing when inspecting or servicing the air suspension system. A sudden release of air under this amount of pressure can cause possible serious or fatal injury.

WARNING:

Support the vehicle by supplemental means before performing any work on the air suspension system to prevent the vehicle from changing height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without supplemental support, or with pressure in the specific component, can cause possible serious or fatal injury.

CAUTION:

When removing an air line from a component and the air line is to be reused, do not remove the 90° fitting or the brass fitting from the air line. If either is removed, the air line must be replaced. New components have air line fittings attached; however if the original air line is used the original fitting must also be used. Do not remove protective caps or plugs from air lines or components until ready to install the air line to prevent moisture or dirt intrusion. All air line fittings must be hand started to avoid cross threading.

With a scan tool, using the routines under the Air Suspension Control Module (ASCM), perform the following:
- Run the Fill Spring From Reservoir routine on the spring that was installed. Choose the Short Time Fill option from the menu selections and the spring will inflate for approximately one second, then verify the air spring is properly seated into its mounting sockets, and any wrinkles in the air bag have unfolded properly.
- Run the Fill Spring From Reservoir routine on the spring that was installed. Choose the Complete Fill option from the menu selections.
With a scan tool, using the routines under the Air Suspension Control Module (ASCM), perform the following:
- Command the vehicle to Normal Ride Height.
- Run the Air Mass Calculation routine on the air suspension system.
- If necessary, add to the system or deflate to atmosphere using the ASCM routines, then repeat the Air Mass Calculation routine again until system responds with Air Mass OK (188 - 216 bar-liters).
- Enable the air suspension system.
Perform the ASCM Verification Test. Refer to STANDARD PROCEDURE .
