Hi.. i have a 2004 range rover and on the message center it tell me that the air suspension is inactive, hdc is inactive as well as selflevel air suspension is inactive... is there any way i can troubleshoot this problem?

check that you are not in 4 x 4 settings on hard surface as that loads up the transmission making it work harder
that it turn can over heat the transmission oil
check for correct oil level in transmission as too much oil or not enough will also heat oil
take it to an accredited service center that has experience on your make of vehicle for a diagnosis of all problems

In respect of the display message 'HDC inactive'. I have and still do occasionally get the same message. I took the vehicle to a Land Rover dealer and was informed it was a common problem particularly when the vehicle is started from cold and more so during cold weather. The dealers have it registered as a bulletin repair and are able to provide a remedial fix, however it's a case of the display message being present when you take it to the dealer!!!!!

Try using a scanner to read codes or re-activate, also have a look at the air suspensions bag/balloons, might have a leaky one. If so change, check air suspensions activator unit too. Valves may ber bad.

Welcome to Fixya

Air suspension is currently in fault mode. It will have to be re-set by someone who has the Land Rover scantool (either a dealer or an independent shop). The EAS system is inaccessible with a regular OBDII scantool. The car will not allow you to control the suspension height (raise/lower/defeat) until the fault is cleared. Please see this link .

hi today i was driving my land rover 04 plate parked up at a shop and when i got back in to start it the engine took a while to fire up i then drove it home and turned it off when i got there now it wont start although the engine has enough battery power to turn the engine as normal it wont start at all it just turns and turns the engine over and now have hdc inactive message on dash ....any ideas pls

take it to the dealer have them run a code search on your car it will tell all

This error could be casued by a poor battery - particularly in cold weather. If you suspect your battery may be in poor condition, try recharging it over night.

The error can also be caused by a worn suspension compressor.

You could visit a Land Rover dealership or if you wish to save yourself the heavy costs you could visit an independent workshop who can check your car's memory log which may provide further information regarding the fault.

Check www.rangerovers.net for further information.

good chance broken line going to that cylinder. it is still pushing air but just not making it all the way there look at the bleeder valve or the fill valve get spray bottle with soapy water spray suspension in the area of the valve look for bubbles.

check owner manualis ha a swich i can remember togod but some of them work by it self when you put the gear working. star the car open the hood close to the front yopu have to hear like a little compresor that means this device is working. you remember someone jack it up the truck and forgot to shut of the swich????

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
