Thought we had this sorted but just had to use the FF and they have come on again as follows, start car and it displays HDC inactive and the abs light and brake warning light both glow yellow, the warning triangle is also lit yellow, air suspension working, as soon as the car moves ais suspension inactive comes up and the hold light on the height adjuster illuminates, the brake warning also changes to red.
reading it the other day with a Snap on Verdict, just upgraded all the abs sensors are comunicating, we reset the steering angle sensor (calibrated) and all seemed fine fo prob 100 miles, these faults happened as I started the car, the bat didnt seem to labour and it was new prob 18 months ago. Im stuck on the couch recuperating from a motorcycle crash that almost killed me but im hoping one of the lads from work will bring the verdict down tonight but was hoping the sequence of events may give one of you guys a clue to the possible fault.
Car is 2002 4.4 vogue. Thanks guys One day your life will flash before your eyes......................................make sure yours is worth watching!

This sounds like the aftermath of a battery disconnection.

Try a steering wheel lock to lock and see if that clears the lights on the dash.

If HDC Inactive persists that is an indication of battery on it's way out. Mine is doing it now, two years after a new one.

All that said if you have had all the ABS sensors changed, there may well be something still wrong in there somewhere. All the sensors are interlinked (and I don't just mean the ABS ones), so if one fails, they all tend to fail and issue warnings. .

I know what you mean re the HDC but how about the EAS inactive that only come on when it moves, We changed about a year ago FRH ABS sensor and RLH ABS sensor, I bought 2 more but apparently the sensors are working fine so they never got fitted. We also had to put a new end on the loom to the ABS pump after a hose burst, this was a LR part and sold as a repair kit as the original used to let water in the loom apparently. Hopefully one of my lads will pop round later with the verdict and I can record voltages and fault codes etc but it seems speed related as far as the EAS goes, I may put the new ABS sensors on that way they should all be new, after that its cheapest parts first, height sensors, battery abs ecu (unless I can borrow one to try) One day your life will flash before your eyes......................................make sure yours is worth watching!

Have you done this:

Try a steering wheel lock to lock and see if that clears the lights on the dash.

Its essential after battery disconnect.

bat has not been disconnected guys, car has been fine for a week, hobbled out to it today and started it and the lights were on with warnings, it did rain very hard last night though! Coincidence? Done lock to lock and whenever its done it before only a reset clears it. One day your life will flash before your eyes......................................make sure yours is worth watching!

I get a HDC inactive message from time to time and more so after my weekend of battery antics. The message clears as soon as the car is started though and as far as I am aware had no effect on the car. I'm fitting a new battery tomorrow so will let you know if it makes any difference at all. Ill do a fault scan before & after also.

The only other thing I can think of is that when it starts the voltage really dips and puts the lights on but it does not struggle to start at all. One day your life will flash before your eyes......................................make sure yours is worth watching!

It's got to be something along those lines, mine pings on as the ignition is turned to the 2nd click and as the glow plug pre warm is running. As soon as the ignition is cranked everything is back to normal.

Ok just went out and checked bat voltage using the on board diagnostics and when I got in the car which was last driven yesterday it was 11.4, after running it for a few mins and switching off it was 11.8, seems the bat that has been in there 2 years almost is now pretty goosed, I think first move is change batteries as logically this fault has occured without the car turning a wheel so it can really only be electrical. On a side note the onboard diagnostic and fault clear function will not clear this fault. One day your life will flash before your eyes......................................make sure yours is worth watching!

Have you checked the battery voltage with the engine running at about 2000rpm?

if you could get a multimeter on it the idle should show around 14.5v... ... - .- -.

Im stuck at home pretty much confined to the couch with broken bones and other stuff from my bike crash, hoping someone comes down with our verdict diagnostic machine later. One day your life will flash before your eyes......................................make sure yours is worth watching!

been watching ceebies all day then..

i suppose it is a bit difficult and frustrating not being able to get to the range to do stuff, speedy recovery btw.. ... - .- -.

Thanks Stan, yeah bored stiff, watched all the good progs on sky and they are now repeated !!! Also got a TR6 I just bought and have loads of bits to bolt on that as well, still I was classed as a fatal accident for the 3 weeks I was in a coma so things could be worse !!!!  One day your life will flash before your eyes......................................make sure yours is worth watching!

its karma, not your time yet....  ... - .- -.
