3. Prior to Installation: Diagnosis Checklist

Before installing a replacement air suspension compressor, it is crucial to review the following checklist. Air suspension compressor failure is generally the result of failure(s) in other system components, such as the compressor relay, fuses, leaking air bladder(s), valve block, or air lines/fittings.

Wêne 3.1: Compressor Diagnosis Checklist. This image displays a detailed checklist to be followed before installing a new air suspension compressor, covering suspension system codes, fuses, relays, connections, VOSS fitting and valve connections, height sensors, air springs and full strut assembly, valve block, and air lines.

1. Suspension system codes: Bê guman ji nû veview all Diagnostic Trouble Codes (DTCs) prior to new compressor installation.
2. Fuses and relays: Check for blown fuses and ensure the relay is working properly. A failed compressor relay is a top cause of air compressor failure. They normally fail in the "closed" position and should be replaced during compressor installation.
3. Têkilî: Verify that the air line and wiring harnesses are connected without signs of physical damage.
4. VOSS fitting and valve connections: Ensure that the VOSS fittings and valve connections are fully seated and undamaged. Make sure that the airline is secured at the proper depth.
5. Height sensors: Check the electrical connections and the orientation of the height sensor arms.
6. Damage to air springs and full strut assembly: Inspect the air springs and/or air struts for any signs of excessive wear or moisture. Moisture in the system is generally an indicator of a leak elsewhere in the system.
7. Valve block: Check all valve block connections and fittings; inspect for any cracks or other damage.
8. All airlines: Inspect the air lines for kinks, holes, or other damage.

MAKE SURE ALL DOORS, HOOD AND TRUNK ARE CLOSED COMPLETELY before and after installation procedures.

• Normal operation may involve intermittent activation, especially after loading the vehicle or during changes in temperature.
• Unusual noises, frequent cycling, or failure to maintain ride height may indicate a system issue requiring inspection.

• Dryer Function: The integrated dryer helps remove moisture from the air system. Ensure the system remains sealed to prevent excessive moisture ingress.
• Paqijbûnî: Keep the compressor area free from excessive dirt and debris to ensure proper ventilation and operation.

7. Destpêkirin

If you experience issues with your air suspension system, consider the following common troubleshooting steps:

• Compressor Not Activating: Check fuses and relays related to the air suspension system. Verify electrical connections to the compressor.
• Vehicle Not Reaching Ride Height: Inspect air springs, air lines, and valve block for leaks. A significant leak will prevent the system from pressurizing.
• Compressor Running Constantly: This often indicates a leak in the air suspension system, causing the compressor to overwork to maintain pressure. Refer to the "Prior to Installation: Diagnosis Checklist" in Section 3 for a thorough inspection.
• Dengên neasayî: Investigate any grinding, squealing, or excessive vibration. This could indicate a mechanical issue with the compressor or its mounting.

For persistent issues, consult a qualified automotive technician or contact Arnott customer support.
