EAS (Electronic Air Suspension) fault — car on bump stops
- Symptoms
- Dashboard warning, ride height stuck low or high, compressor runs long or not at all.
- Likely causes
- Perished air bags, valve-block O-ring leaks, worn compressor piston seal, or a failed height sensor.
Troubleshooting steps
- 1.Read EAS fault codes with a Nanocom, Faultmate, or GAP IID Tool.
- 2.Soap-test each bag and valve-block port to locate leaks.
- 3.Rebuild the compressor with a piston liner + seal kit (cheap and effective).
- 4.Replace all four bags together; recalibrate ride height after the fix.
