Adapter Air Line

ADAPTER AIR LINE

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.

NOTE:
New fittings must be used with new air lines, and new air lines do not include new fittings.





1. Position the adapter air line (2) and connect the adapter air line retainer/routing clips on the valve block bracket.

2. Remove the adapter air line fitting/plug from the adapter air line just before installing the reservoir air line (2).

3. Install the reservoir air line/fitting (2) to the adapter air line connection and tighten to 5.5 Nm (49 in. lbs.).





4. Install a new air line fitting on the compressor and tighten to 5.5 Nm (49 in. lbs.).

5. Remove the adapter air line plug and install the adapter air line into the fitting (1) by pushing the line straight into the fitting until seated, then pull to verify it is seated.





6. Install the Air Supply Compressor stone shield.

7. Install the RR wheel inner liner.

8. Install the RR tire and wheel .

9. Remove the supports and lower the vehicle.

10. With a scan tool, using the routines under the Air Suspension Control Module (ASCM), perform the following:

- Return 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 the system responds with Air Mass OK (188 to 216 bar-liters).

- Enable the air suspension system.

11. Perform the ASCM Verification Test ASCM Verification Test.
