    Bus Suspension Air Spring: Common Troubleshooting and Diagnosis Table


    SymptomPotential CausesDiagnostic Methods & Corrective Actions

    Symptom Potential Causes Diagnostic Methods & Corrective Actions
    1. Vehicle Leaning (One Side High, One Side Low)
    • Height valve linkage stuck or damaged
    • Severe air leak in the corresponding air spring
    • Air line blocked or kinked
    • Faulty height valve
    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.
    2. Body Will Not Lift (Stays in Kneeled Position)• Air compressor failure/inoperative
    • System pressure too low or major leak
    • Clogged air dryer or multi-circuit valve
    • Main air supply valve closed
    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.
    3. Unstable Vehicle Height• Height valve maladjusted or slow to respond
    • Internal damage to the air spring
    • Intermittent leak in the air system
    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.
    4. Abnormal Rubbing or Noise During Driving• Air spring rubbing against adjacent components (guard, frame)
    • Air spring surface damaged, cord layer exposed
    • Piston (if equipped) corroded or deformed
    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.
    5. Premature Aging or Cracking of Air Spring• Cleaned with inferior chemicals (e.g., gasoline)
    • Prolonged exposure to ozone or extreme weather
    • Long-term corrosion from oil, grease, or solvents
    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.
