EAS Unlock calibration weirdness

Don't think you understand. By solenoids i mean the actual electro magnet that fits over the valve. The one with the wires to it. If the electro magnets are transposed FL FR this will give you your problem. Quite easy to do IF you don't mark their positions when you strip the block.

With you now. I haven't had the valve block apart yet though, although it's possible the previous owner did as he's done some things in that area ie non standard compressor and some wiring mods.

I'm hoping I was just barking up the wrong tree with that theory - I just can't get the FR to move via the calibration screen. Doesn't help that I haven't got any level ground here - flat yes, but on a slight slope.

I'm going to clean the connections, lube the linkages and try again. I tried it on the public road at the bottom of my lane, but the laptop battery only lasted 10 mins.

The missus is giving me evils now too - is not my fault and she was supposed to be out today anyway!!
 
Ok just about got the heights set right but I'm still getting the target heights are incorrect message.

I'm guessing this might be because the low profile values are higher than those for the standard but I didn't think this was settable?

Anyone know what the low profile height should be?

25mm lower than the standard height. Standard 470mm from centre of wheel to arch. Low 445mm from centre of wheel to arch. It is settable but was not supposed to be selectable. That has been disproved in another thread.

Thanks Wammers. All done now.

It's weird, ALL the heights were way higher than they should be - even access height was about what low should be. Nomal was almost High and High was 2 cm higher than it should have been.

I'm wondering now if the previous owner changed them all cos the pots are all worn at the standard heights. Ah well, I spose I'll find out!

Thanks again all. It drives much better now.

I spoke too soon...

Noticed when I got to work this morning that the front left corner looked a bit high.

Checked it when I got home and the damn thing has reset the heights on that corner.

It just won't accept any heights I put in - not even the default ones that it puts in itself when I clear the fault - it just reports 'target heights are incorrect'. I assume the problem is with the front left because that is the only corner that it resets - all my other values stay the same.

Now the values for that corner at all heights need to be a lot lower than the other corners to get the correct physical height and I assume that this is causing a problem with it's internal stored values.

When I plugged the EAS kicker in, it reports 'Height sensor data is not valid'.

Does all this suggest that the height sensor on that corner is knackered, or am I missing something? It didn't look bent or anything when I lubed them all yesterday which is the only thing I could think of to explain the discrepancy in values..

Any ideas anyone?

Guy, Having done all that you have I would suggest that heightsensor either has a dodgy/corroded terminal or maybe totally shot? Island 4x4 do them pretty cheap (bout £60 if I recall).....try disconnecting/cleaning plug, otherwise swap the two on thataxle to eliminate before buying another!

Hi Paul,

I did clean all the connections, but they looked ok. The FL one has lost it's heat shield though (although my cats have been emptied anyway so don't get very hot). I suppose it may have been cooked in the past.

I'm wondering now though - the front right requires much higher values than all the others for the same height, but it's the FL that keeps having it's values reset by the EAS computer. BUt even the 'default' values that the EAS system puts in still result in the error message, although I can clear it and they stay set.

That's not a bad price from Island. Tempting, but I'd rather know for sure that this is the problem before replacing it.

Waaah!

I'm thinking I might just replace both of the buggers - at the Island price it's not too bad but I'd like to try and understand what's wrong first.

The fault my EAS Kicker is reporting isn't even listed as a valid fault on BlackBox's website! Apparently if I pay, I can upgrade it so I can set the heights through that, but I suspect I'll still have the same problem.

Hi Guy, take the sensor off and see if it moves smoothly throughout it's travel, if it does, put an ohm meter on it and see if the resistance varies smoothly as you move it. If it fails either test it's shot.
Have a look here:- Height sensors useless info sorry can't get the link to work, just put that into the search for photo's of what happens to the innards of a height sensor

Thanks for the encouragement! ;)

Not sure where to go with this. According to the EAS Unlock manual, only one of my figures is outside the allowed range which would case the EAS to reject it, but it won't accept it if I change it to an allowed value either.

Hi Keith,

Can't find any piccies quickly - I'll have another look at lunchtime.

In case anyone is interested the values I need to set to get the car to the correct heights on each corner are:

FL FR RL RR
High 120 140 130 120
Standard 95 125 105 96
Low 73 102 86 79
Access 50 64 62 55

but it won't accept the values for FL and keeps resetting them. 73 is apparently out of range for the low profile, but it won't accept any of the others either. I might try taking it off if I haven't sorted it by the weekend...

Try lifting the values for low by two units all round then it should accept the settings. If you try to enter an out of range setting ECU reverts to stored basic default settings and you have to start again. You could try loosening the sensor and see if you can move it on the bolts a little as the FL seems to be low on all modes so does RR.

Hi Wammers,

Hmm. I'll try that this evening. I've concentrated on just adusting the FL figures. But I did put the entire set of original values back in out of frustration and it wouldn't accept them either!

Good shout about trying to move the sensor though. May have to wait until the weekend though. Grr.

As for checking the sensor, should I be able to do that using the Heights screen? I can make the corners go up and down on that screen, but none of the height data is refreshed which seems a little odd. I would expect the displayed heights to be live data otherwise what's the point of that screen?

Guy
 
Bleeding thing. Spent about an hour trying to convince it to accept any values at all and then after an hour and a half of cursing and threats it started to accept my original numbers and now they're all in. Ish.

My EAS Kicker has decided to pack up this evening too so I can almost guarrantee that I'll have an EAS fault again in the morning when it decides it doesn't like my new settings any more.

I dare not touch it again!!

make up a set of blocks to go betwix axle and chassis so it sits at the level you want when the air is out of the bags. read off what the sensors are saying and then input those figures into the relevant section.

Problem is official blocks have 2 sizes and we need 4 sizes in EAS Suite unlike with Testbook

Correct me but access mode isn't fully on the bumpstops.

You don't need any blocks with the EAS suit, it's easy enough on flat ground with a tape measure. If you want blocks, just make them up out of hardwood like Oak.

Easy enough!??:eek: In theory perhaps...

My Rangey didn't throw up an error this morning so it seems happy with the new settings at loooong last.

I wouldn't have believed how much better it drives - what a difference!
