Common Troubleshooting
| Symptom | Potential Causes | Diagnostic Methods & Corrective Actions |
|---|---|---|
| Vehicle Leaning (One Side High, One Side Low) |
|
Diagnose: Start the vehicle. Observe if the height valve linkage on the affected side moves normally with body height changes. Listen for audible air leaks. Correct: 1. Lubricate or adjust height valve linkage; 2. Check for leaks on the air spring and lines using soapy water and replace; 3. Inspect and straighten air lines. |
| Body Will Not Lift (Stays in Kneeled Position) |
|
Diagnose: Check if the system air pressure gauge is in the normal range. Listen for compressor operation. Check if the air dryer is venting properly. Correct: 1. Repair or replace compressor; 2. Locate and repair major leaks; 3. Replace air dryer or service valve; 4. Open the main air supply valve. |
| Unstable Vehicle Height |
|
Diagnose: Test repeatedly on level ground. Observe the response speed of the height valve and the smoothness of air spring inflation/deflation. Correct: 1. Readjust or replace height valve; 2. Inspect air spring for irregular bulges or wear and replace; 3. Tighten all air line connections. |
| Abnormal Rubbing or Noise During Driving |
|
Diagnose: Inspect the air spring surface for unusual wear patterns, especially on the sides. Check for correct installation alignment. Correct: 1. Correct the installation position to ensure sufficient clearance; 2. Replace worn or damaged air spring. |
| Premature Aging or Cracking of Air Spring |
|
Diagnose: Check the air spring surface for uniform micro-cracks (ozone cracking) or signs of chemical corrosion. Correct: 1. Replace air spring; 2. Avoid cleaning with harmful chemicals; 3. Regularly inspect and clean the air spring surface. |
