If I can sort the lowering to Access Profile, all may be OK. While I can't lower to Low (Highway) Profile when stopped, the car will drop to there on the highway.

I suspect yours has different sensors and that's why the bit counts are so different.

from memory..

aren't there pre-requisites for accessing som of th modes?

th

Yes, there are. They are listed in the owner's handbook.

Her car also happily dropped down to access this morning. It's never done it for me before (with Gen 3s), not that I drive it much.

All 4 regular modes can be selected with the car stationary. The only mode that can't is the extended mode which the ECU selects when it thinks the chassis has grounded.

Hi Ron,
I also have Gen III's and hard range lift kit.
I have also recalibrated the settings in EAS with Storey Wilsons program.
I have no problem changing from access thru to extended.
Check that your values for each height are within that heights range.
Otherwise you may have a sensor issue.
I have posted all my heights etc previously also the ranges that need to be adhered to.
Hope this helps.

AS you know the car is for sale (possible buyer coming tomorrow).

But I couldn't sell it with the EAS issue - which is now fixed. I tried recalibrating again but to no avail so replaced the valve block and driver pack and all is well. I have no idea where the problem lies as the valve block had been rebuilt a few months back. If I had more time, I'd try changing only the driver pack.

Figures with Nanocom after calibration with LR calibration blocks. Note. however, the calibration was done yesterday with the old valve block, not the new one which was fitted today.

I'd say the driver unit is the culprit. They are getting on now! Mine was giving issues on the drive to its new owner with a rebuilt valve block (and no leaks), it's either the right rear solenoid or the driver unit on it.

I haven't priced driver units, but if you have a known good spare that's my first port of call.

How disappointing! The new owner called me from Kempsey this morning. The Rangie was reluctant to come off the bump stops. It must have lost air overnight and the compressor might be getting weak even though it was rebuilt earlier this year. I used to have a light on the dash to tell me when the compressor was running.

The valve block I removed didn't lose air so I don't know if the replacement is. Fortunately, I had given him another compressor which I rebuilt t the same time as the one in the car. It has a new piston ring, cylinder, filter, and O-rings. Compressors are very easy to change.

The P38A does have a manual inflation kit installed and an EAS disable switch so, if needs be, the corners can be inflated and the EAS system, including compressor, switched off.

I'm really upset about this.
