    EAS Fault

    Guy's I need Some help,

    I have an EAS fault problem. Firstly all the lights on the EAS dash lit up and are constantly on. I couldn't manually change this. The dash was saying the suspension was set high for 4wd. This continued for a couple of days then I lost the suspension. Called into a garage and they hooked it up to their computer erased the faults and the suspension rose again. There diagnostics showed the suspension overcharged. All was well for 2 weeks then the same fault occurred again.
    Can someone give me an idea on what I need to be looking at as a fix.
    1996 Range Rover 4.6 HSE

    Thanks,

    Bara

    there are several possibilities:
    (a) the diaphragm in the valve block may need to be replaced

    (b) the "driver" unit AIR SUSPENSION DRIVE BOX needs to be replaced

    (c) replace the o-rings in the valve block

    you need to read/re-read the information in Air Suspension Faults, Diagnosis and Repair

    and PaulP38a 's "HardRange"website

    If you haven't replaced any of the above, i.e. they're still original, then my bet on erratic behaviour is the drive box...


    Edit: if you are serious about getting to know your P38 then download Storey Wilson's free software (EAS Unlock), buy the requisite cable from PauP38a Hard Range and you will have complete access to your EAS to read and clear faults, diagnose problems, recalibrate the height sensors etc... total cost : probably less than 30 mins time at the local garage!

    Hoges,

    Thanks for all your help. I'll start at the beginning and work my way through.
    I am serious about getting to know the system and will look into the sites you recommend.

    Thanks for all your help,

    Bara

    I agree with Hoges - get Storey Wilson's software and start reading everything you can get off the net. I have replaced two rear bags, compressor piston and done the valve block. If you have to go all wthe way then: Take your time, take lots of photo's as you work your way through. When in the valve block make sure you take extra lots of photo's and a felt tip marker comes in handy to number things and place alignment marks on them. Keep the work area absolutely clean.
    ps. Be careful - the system is under pressure, make sure you release it correctly (Storey Wilson's software has the function to safely release it.) And as always don't work under the RR without blocking it.
    All the best with the challenge.

    Just one more hint: I found that a largish table covered in butchers paper taped down and marked into 100mm x 100mm squares provides an excellent 'map'
    for keeping track of parts...you label the squares and ... (also especially handy when replacing a display screen in a Macbook pro )
    cheers
