Does anyone know whether I can use Nanocom to monitor the EAS whilst driving ?
Thanks,

The EAS goes into diagnostic mode when you plug in the EAS cable so I'm not sure what would be achieved running with the Nanocom pluged in and the EAS software selected?

If its like the kicker you can see the data from the height sensors when driving?

Quite possibly but it will not tell you much that is useful and as the ECU will be in diagnostic mode I think faults will be inhibited as will be self leveling.

Simelise uses a kicker to check height sensors on a test run
he lives on the back of the forest so lots of uneven ground to put the sensors through there paces
Just shows if there's 1 throwing a fit with the live data from them,nothing more than that like you say

You would have to be bloody quick to see anything or the fault would have to be permanent.

Should have said . . . main reason is at steady speed on Motorway, every few minutes the car seems to tilt forward. Not sure if it's the back rising, or the front lowering !!
The EAS drops from normal to motorway height correctly at 50mph, and rises back 30-60seconds after speed drops below 50mph.
and then once or twice a week it randomly goes to extended height, but a quick press on the dash button puts it back to either normal or motorway depending on the speed.
Not had a chance to check the LHS footwell connectors yet. Height readings seem ok at all heights when parked & adjusting manually.

Be interested in the results of that. Mine does the random back rising on it's own too.

Driver pack can often be to blame for that behaviour, part and clean the connectors in the EAS box and check the earth points on the wing between the EAS box and the air filter box.

Driver pack.... bugger that sounds pricey!

Of course no problems, the EAS goes into diagnostic mode and will not self level or log faults as far as I'm aware. You will see nothing useful from the height sensors unless they are totally fecked as the software is designed to smooth out irregularities in the readings from the sensor track as far as is possible.
Sorry, but that's incorrect.
You get full live sensor readings (I could perfectly see the values of the left and right wheels shift in accordance to the curves I was making, as the car tilts and there's some weight transfer) and I could also see some very small activity in the valves and compressor.

Sure you will see the sensor readings, AFTER the software has removed as much of the crap from the signal as is possible.
You see exactly what the EAS shows under other conditions and the system still self levels. I can't comment on the statement that you won't see any faults though (but I see no reason for them not getting logged).
Actually, it seems that the system enters diagnostics mode only very briefly (you'll get some beeps and the max speed warning) but it then exits and there's no more warnings and the system is working as if the nanocom wasn't plugged in.

As long as there are OBD comms, the EAS remains in diagnostic mode, the max speed warning is the indication that diagnostic mode has been entered.
All inputs to an ECU use algorithms to smooth signals from switches potentiometers etc, put a scope on a height sensor and you would be amazed how ragged the signal is.
Electronics isn't certainly my area of expertise and you're far more knowledgeable about it than me.
I'm just trying to explain that, from my experience yesterday, the system seems to be running fine, with nothing of its normal operation affected when you plug in the nanocom.

Tried it today on way home from work. Usual beeps & lights when entering EAS daignostics, but then EAS seems to return to automatic operation & dash light goes out, but with data flowing to Nanocom.
Nanocom display does show height readings changing slightly with road bumps, but the slow Up-Down cycles didn't seem to happen as much. The usual height change drop at 50mph does still happen though. Also switching to manual on dash works at any speed.
Saved input readings for about 10-15 mins, but when I got home found the Nanocom had saved the files to internal storage because it didn't recognise my SD Card, so I cannot extract the file. Replaced SD Card with another one, so will repeat tomorrow !!
One thing I have noticed is in both Standard & Motorway heights, the right front & rear readings never get close to demanded values (about 5-10% higher). The left front & rear always get new demanded values. Maybe I need to make some blocks & re-calibrate, because the car does feel leaning to left from inside, but doesn't look like it from outside !!

OK so I'm wrong about the self leveling in diagnostic mode but I can assure you it remains in diagnostic mode while the comms is activated, others have found that by leaving a kicker plugged in the EAS will not go to a hard fault and have used it as a get home trick, from that it's fairly safe to assume that no faults are logged in diagnostic mode.
I'm not wrong about the sensor outputs though.
