AIR SYSTEM FAULTY OR INOPERATIVE
Check and replace EAS system fuse F44 (10-amp) located in engine compartment fuse box. If fuse blows again or fuse is okay, check wiring for an open or short. See WIRING DIAGRAMS.
Check and replace instrument panel height control or inhibit switch fuse. Fuse F17 (10-amp) is located in Body Electrical Control Module (BECM). If fuse blows again or fuse is okay, check wiring for an open or short. See WIRING DIAGRAMS.
Check for inoperative EAS air compressor. Ensure EAS air compressor electrical connector is clean and tight. Check maxifuse No. 2 (30-amp) located in engine compartment fuse box. If fuse blows again or fuse is okay, check wiring for an open or short. See WIRING DIAGRAMS.
If EAS air compressor operates continuously, check EAS air compressor relay. Relay is located in engine compartment fuse box. If relay is okay, check wiring harness for a short. See WIRING DIAGRAMS.
If EAS delay timer relay fails with a closed circuit, the EAS system will be powered, causing battery to be drained. Check EAS delay timer relay located under left front side. Replace EAS delay timer relay.
If there is loss of EAS system air pressure, check for a leaking air spring, or a leaking or faulty air spring diaphragm. Check EAS system air harness connections and lines for damage, scoring or leaks. Air spring is not repairable. If it is leaking, air spring must be replaced.
Check for damaged height sensor linkage or linkage mount. Repair or replace components as necessary.
A faulty height control switch could result in vehicle height remaining at last height setting until ignition is turned off. A faulty inhibit switch could result in vehicle height not operating automatically between standard height and low height positions. Use Land Rover TestBook to confirm either switch. Replace switch or repair wiring harness as necessary.
