Range Rover L322 EAS Fault Codes
Complete reference library of Electronic Air Suspension (EAS) fault codes for the 2002–2005 Range Rover L322. Each code explains the fault condition, what triggered it, and what it means for your air suspension system.
Read and clear these fault codes yourself with the All Comms diagnostic tool.
The All Comms tool connects directly to your L322’s air suspension ECU, reads stored faults, calibrates the system, and clears codes once repairs are made.
