    If there is no diagnostic connection, having moved a corner to the required height with your box of tricks, how do you read the bit count to write it back?

    Depends what I'm doing. As you said above with RSW software it's easy to move corners up & down and then write them.

    With Nanocom it's more awkward (albeit possible) to do without Up & Down buttons, so I use my manual box connected to valve block driver, and Nanocom to read the values.

    I also use the manual box to extend front or rear manually when working on car, because I'm a short-arse. i.e. when doing stuff that requires above & below engine, etc. it makes it really easy to raise & lower as needed with engine off. It also automatically controls an airline solenoid plus diaphragm valve, so I can have the tank refill from workshop compressor rather than using the pump.

    Diag appears to be ok but sensor doesnt get to set height.
    I need to get another copy of RSW software cos my old one doesnt seem to work anymore

    Is the rubber con-rod perished that is fitted to the h-sensor lever r the rubber perished or split where it is fitted to the lever ?
    This can cause issues sometimes

    That is sometimes a sign of a high resistance connection.

    Ok that figures as this is the third time that sensor had been replaced.
    Cleaned contacts with contact spray when I changed it but wonder if its iffy under the seat. Carpets are dry

    The wires on the link-lead to the sensors connection sometimes bare the wires under the insulation and touch the other wires. Would not think its this problem but I have had some very intermittent strange readings and going on before I found it on customers vehicle.

    Interesting I wonder if the main lead is faulty mid length rather than at connectors

    Good idea
    Just changed bump stops so will try and calibrate again tomorrow if I can get a new copy of RSW software

    Hi Kurt, I have been fighting an intermittent fault for a very long time, have replaced with new rear sensors (fault always seems to be from the rear) I have cleaned all connectors and removed the white one behind the kick panel. When I have tested continuity from the rear all seems ok. Is it a straight run from the sensors to the ECU or are the any other nefarious connectors in between?

    I have found issues a couple of times with the lead that the height sensor is plugged into. The wires become hardened and corroded or wear and cause intermittent faults.

    Thanks mate, I checked the connectors and they seem not too bad to be fair, I was wondering if there were any connectors between the sensors and the ECU. I can’t see any on the wiring diagram

    They should be part of the main body loom. I never found any intermediate connections, but don't rule out hidden LR splices within the loom that are not on the diagrams !! RAVE does have omissions & mistakes in places.

    Calibrated her today at last.
    Had changed one of the rear sensors
    With blocks in place all sensors gave sensible answers except the new one.
    The original side read 109 and the new one 147 !!!!
    Of course that figure wouldnt be accepted.
    Took the wee arm off the spring and moved it up and down lots of times and cleaned the contacts on the leads.
    Tried again and now read 112 so accepted that and seems to be working fine so far
