If no misslock and no cods it's OK from this point of view. the SLS and ORM warnigs are working on ignition self test?

You should connect hawkeye again to check for codes to be sure it didnt store one since fitted then go to live data and see height sensor inputs also in ''circuit test'' try to activate the compressor to see if it kicks in or not. if it does better recalibrate the system, v.6 can do that, you have to support the rear of the vehicle on the desired level with two jacks or one under the towbar if it's on plain ground then go through the ssteps untill it asks about calibration blocks and confirm. this way the system wiill store those heights as being the target
 
Went into chassis section on Hawkeye & tried to do SLS cicuit test & it said SLS RR & then Rl Circuit test not supported. Again there were no fault codes so I then went to live data & got this.
31 SLS right not fitted.
32 SLS height left not fitted.
33 Valve supply RR not fitted.
34 Valve supply RL not fitted.
35 SLS Valve supply not fitted.
36 SLS LR valve not fitted.
37 SLS exhaust not fitted.
38 SLS compressor not fitted.
39 Doors not fitted.
So I didn`t go any further trying to calibrate as it seems therein lies my problem ? Could it be the slabs came off a discovery with coils fitted ? I never asked the question when I went to the breakers.
 
Something is wrong there but it's first time i see such thing, i'll have to think about it, at least we know why it's not working but at first sight this ECU is suspect too, are you sure it's in 100% working order? check to not be in transport mode... what about the ABS live data side of it ?
 
To answer my own question the replacement slabs ecu was set to coils & have now changed this. Will now try jacking it up on drop plate to see if I can get both sides measuring the same 470mm +/-15mm from hub centre to bottom of wheel arch.

I asked about the SLS warnings self test exactly to rule out the coil setting but AFAIK(actually i'm quite sure) that if it's set to coils the warnings should not work at all so it's another oddity. :confused:
 
Also neglect the sensor readings for calibration, important is the body to be on straight level even if the readings are different cos the ECU stores the voltage inputs as targets at the body's physical height if you see what i mean.

Yes so as long as it`s level horizontally & the height measurements are in range then it will go from that. Upon changing the setting from air to coil though it throws up loads of dash lights, but no codes so it seems like the replacement slabs is no good to & probably why it was on coils setting. I will put up a pic as when changed back to coils dash is fine.

As long as hawkeye is connected all the warnings are on that's how it is but once set to coils and hawkeye removed the SLS warnings should be off for good, no self test, nothing. Anyway if you can manage to lift sides by inflating bags with hawkeye and put it on level if there's no leak it will stay on that level for many days if it's set to coils...at least untill you fix it
 
Right the suspension levelled itself & with it set to coils all lights are off. Those other dash lights disappeared once Hawkeye was disconnected as you said they would. However with it set to air & Hawkeye disconnected I am back to having the SLS & ORM button lit up on the dash. Can it really be coincidence that both SLABS ECU have the same fault or is it something wrong elsewhere in the SLS system that does not throw up a fault code ?
This is so frustrating.
 
too bad we worked so much while it wasnt set to air from the beginning but that's it now... if the symptom with this ECU is the same like with the other i doubt it's that... can you read live data now and see the status of those two warning lamps? if it says ''off'' while they are on the problem is on the circuit somewhere, do you have RAVE?

I will look through to see what those warning lamp status are. I do not have Rave but it if you have a copy of it that would be very handy. Off to check now on MIL status.

Thank you. Yes I have a multimeter & with guidance should be alright checking the circuits, but I can`t seem to find those lamps and the section that tell me if they are on or off.
 
I have both hawkeye and nanocom and i didnt use hawkeye lately but IIRC it should be in ''live data - outputs" if it's not there maybe it's missing from hawkeye's capability ... without seing the ECU output all you can do is o measure voltage across a live from the fusebox and C0233 pin 2 and C0230 pin 9 with connectors unplugged ... see Electrical library - connector views for the pinout , you'll have to remove the binnacle which is not hart and concentrate to measure on the right pins... The gist is that the warning lamps are coming on if there is earh or nothing on those wires as the ECU keeps the lights off by switching on live to those pins if the system passed the self test... the problem is that if you get nothing or earth there and you can't see the ECU outputs you'll have to measure at the ECU pins across earth and C0655- pins 8 and 11 with it connected. Good luck
 
Wow that list is in depth & I am currently looking through it now for those connectors & coloured wires. So it seems that those wires have possibly earthed themselves to make those lights come on then ?
 
Earthed or interrupted and IF the ECU does it''s job to extinguish them with live output that output doesnt reach the instrument pack or if it does the problem is within the IP... did you check for outputs in hawkeye menu and no joy?

I will try to check the instrument pack tomorrow. what outputs am I looking for in Hawkeye ?
 
Also I forgot to answer one of your questions earlier wich was that the ORM & SLS light come on & go off again in the instrument self test when you first turn the key, but without starting.
