Hdc inactive range rover - 2004 Land Rover Range Rover

SOURCE: hi.. i have a 2004

The EAS can have many different faults that will give the same warning. I have had several air susp problems. First try to disconnect the battery, wait several minutes reconnect then drive car making at least on full circle. If lights remain, air pump (under spare tire ) can be checked, also valve under a cover behind right front wheel, other than these areas, the Testbook diagnostic at dealer will determine if any other parts are source of problem. Unfortunately, with the complexity of the system many other parts Height sensors, etc, etc can also cause the error message. Good Luck.

Air Suspension Inactive usually means there is a problem with the Air Suspension. However, it will also come up when alternator or battery voltage is low, or when you reset (disconnect and then connect) the battery. To reset it manually: while in P(ark), turn steering wheel all the way left, hold few seconds, and then all the way right, hold few seconds. All the warning lights will go out. Most common failure is the passenger front air strut, since batteries are prone to leaking acid, it leaks right on top of the rubber airbag and burns through it. Dealer willcharge you one hour to diagnose, or you can easily diagnose this by looking at the ride height of each particular corner of the truck. If its sits low, or emits hissing sound when you park the truck, its leaking. If you keep driving with leaky air strut, you risk burning up the air compressor, as its working extra hard to compensate for the leak. Replacing the strut is easy 45min job even for a novice mechanic, and you can do it yourself. Strut can be found new for approx $750 online. If you are fed up with air suspension issues, there is a $700 kit that converts the truck to springs, and disables all of the air suspension. Look up Arnott Industires
