Bus Suspension Air Spring: Common Troubleshooting and Diagnosis Table
| Symptom | Potential Causes | Diagnostic 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. |
