P38A EAS front extended mode rear standard

[stevebrookman]

Hello all,
Last couple of weeks seems the front of my Range Rover seems to be riding in extended mode whilst the rear is in standard mode.Will drop when I put it into access mode but the front is still higher. Waiting for a nanocom to be delivered and my RSW solutions eas cd (which I found after 11 years) is kaput.

This is what it looks like (road appears sloping but its not-and its like this all the time)
Any pointers please.

Regards

Steve

Calibration wrong in ECU ?

 

[marjon]

Have you taken a tape measure to it, in all the heights?

Check for white powder in the valve block exhaust silencer.

Ahh, a p38 on coke again…….

Thanks all-will measure heights and check for powder -report back in a couple of days.

Thanks again

Steve

Might be worth checking the height sensors show steady readings across their range of movement. Someone said how they checked on here, might have been @Henry_b or @Mark Piercy ?

Twas @Henry_b mate. Have a search using the search box top right.

Mine lost its calibration for some reason and dumped the rear LH corner down and lifted the front..

A simple recalibration sorted it, easily done with a tape measure and RSW software, making sure you are not in the vehicle when doing it and the ground is level.

The height sensors themselves are just simple potentiometers very simple to check once off the vehicle.

Three pins in total two outer and one inner, the outer ones are the either end of the track and the centre is the sweeper.

With a multimeter check the resistance of the two outer pins, you should get a resistance reading, if not and you get an open circuit it's junk, however as yours isn't throwing an EAS fault "yet" this probably isn't the case.

Next up check the resistance of the centre pin while running the arm through its full travel, slowly looking for any spikes in the resistance or any areas where it goes open circuit, the latter being the issue with mine.

You said exactly the same in October 2020. 'enery

Nothing much changes.

It’s good to be reminded now and again

I was reminded today I haven’t got a scooby when it comes to my drivers seat not working despite spending hours trying things and changing outstations and harnesses that’s hours I will never get back so off out to get some more fish for the pond and on the way call into local Indy and try get auto. Electrian out to me

Had a chance of a look today-fronts around 49cm, rears 46.6cm. Will await my nanocom.

Thanks Marjon!!!
