EAS misbehaving in Cape York

neither am I, but worn shockers would not cause wheel slip on the roads and your description of when it happened IMO. Good ones would improve the ride though.

I had a weird occurrence, when dropping in my off-road caravan at the maker's establishment, I dropped caravan's jockey wheel, and lowered the D4 (I have the LLAMS kit) but the vehicle was not lowered enough. So being a smart ass, I lowered the vehicle all the way - via the lowest setting in the D4, plus extra lowering via LLAMS (which was not set as low as it can go either). I drove forwards, and switched off. Then, the vehicle would not gain any height. So a service guy from the caravan maker (Australian Off Road) put his notebook onto the data reader, and found a fault on one of the height sensors. He then re-set the sensors, and shortly after, the D4 rose and seemed to be back to normal. I thought a sensor was faulty, and took it to a QLD LR Indy, who checked it out and refused to charge me (fairly close to Caloundra). They said the sensors were in spec and not worth replacing. I have had no issues since.

So, the first thing I would do would be to reset or get your Indy to reset electronically the sensors. Worth a try IMO.

The height sensors can't be reset as they're dumb devices, sending out an analogue voltage from a 5V and ground supply but height sensor faults can be cleared.

Hi Graeme,

Hope you are all well in your lovely home and property! My best regards to you and your charming wife.

I now do not lower the vehicle all the way ... Instead, I'll wind up the jockey wheel a bit higher. So I'll use your control to lower it all the way, and leave the Disco height switch in its middle setting. Or, I'll have the Disco on lowest switch setting, and I'll have your control one off the lowest setting. Incidentally, you set it up to not be at its lowest capability, as my need started at being able to drive on bush roads at over 50 KMH in a higher mode.

The height adjust for putting a van on and off though, has been priceless. I often have driven up to the van in reverse, and walked back to check the van, and everything is aligned and I then just rise the vehicle. I'd get it right every time but for the camera being off centre, where parallax error results in the D4's tow tongue being sideways from the van's attachment pin.

I wonder why after having lowered it the whole way down, it would no longer rise up ... yet with the faults cleared, it resumed to normal behaviour? I could not see any benefit from a software viewpoint, in leaving the Disco stuck in its lowest position.

I suspect that if I lowered it all the now, without the van attached, it would rise up without any issues. But I've not tried to do that, as I don't have a faults scanner, so I would not be able to clear any faults. I guess I need to get one.

at one time I had programmed, with IIDTool, a lower height for some reason or another and without thinking *also* lowered the car to access height which trigger a height sensor fault (presumably because the car was on the stops or was far lower than it expected to be at access). The fault meant the car was stuck at that low height and the EAS would not respond. But after setting the height offset back to normal and clearing the fault all returned to normal operation. so potentially something similar with LAMS?

in any case - the car is going in for a service in a few weeks so will get the shocks looked at then.

Doug,
If you get a faults scanner then get a IID, they are very comprehensive and will cover anything that you will need to do. I got one as we often go remote and I want the assurance that unless it is catastrophic I have the information I need to understand the problem. As a bonus if you change vehicles you will get back a substantial amount of the cost as a second hand unit.

Cheers

LR had some not very user friendly programming in the D4 and my MY12 L322 is worse! A logged fault can often inhibit normal operation but keep an eye out for the raise and lower switch LEDs flashing as this shows an error state, but pressing the raise or lower button usually resumes normal operation. My L322 won't make any suspension changes, whether changing height modes or levelling, if a message is showing in the instrument cluster, regardless of whether the message has anything or not to do with the suspension system.

All well here thanks, even if a little waterlogged from all the springs that are running, some from spots not seen before in the 25 years that I've been here. But its green and gold time so the countryside looks a treat.
