    SLS error on Disco

    Hi Guys,
    I did a bit of offroad driving last week with the rear suspension raised at times; on several occasions the SLS light on the dash came on then began to flash after a few minutes with the warning chimes sounding (both while rear was raised and also with rear normalised). At each instance I was able to clear the fault by restarting the car.
    I pulled the following error out of the SLABS ecu with my nanocom; any idea what this error might mean and how to fix it ?


    The SLABS ecu contain the following faults:

    FAULT 31-02 rear right corner valve power amplifier open circuit INTERMIT. 000 times
    FAULT 31-03 exhaust valve power amplifier open circuit INTERMIT. 254 times

    thanks

    Hi Stig000,
    Thanks for the reply; the first instance of the dash light coming on was only about 15 minutes up a bumpy firetrail; subsequent errors were after a river crossing.
    Checking the connections at the compressor makes sense, I will remove and clean this weekend.
    I guess my real concern is that this is the sign of something else about to fail such as valve block or over-pressurisation ? I have heard that the exhaust valve can be sticky? i wonder if this would cause the type of error I have logged ? and then if it is possible to clean/fix ?
    thanks.

    airbags

    Hi,

    I just bought a disco 2, it has had the rear bags removed and pedders springs and shocks put on it.

    The service book showed a few entries of sls errors so I guess the owners got the poops with it and put the springs on??

    The compressor unit etc is all still there though.

    I dont know if any problems occur from disconnecting the bags?
