Thread: IQ3 has lost sensor values

  1. #1

    Default IQ3 has lost sensor values

    Hi
    Ive got an IQ3 and for some reason its lost all the sensor values to the dash
    ive tried uploading the file to the dash again and it doesnt upload
    its been running fine for ages but this morning its decided to ignore the USM which has 4 sensors connected

    any help would be appreciated

    So the sensors can no longer be detected on the VNet?

    Have you checked to see if any detents have come loose in the V-Net connectors? Also, if you are using a V-Net extension cable to the back of the dash, make sure that the cable is free of any cuts or other signs of "distress"/

    Let us know if you find anything.

    Sincerely,

    Thx for the reply

    Sorry when i posted this i said Vnet i actually meant USM

    The system hasnt been touched since i fitted it. its been working fine for ages.
    Last week i got back to the car to get it ready for our Round 1 in 2 weeks
    When i turned the car on the values were Zero.
    Ive check all connections and removed and refitted the cables
    I cant see any faults anywhere.
    Even the laptop cant read the USM or upload the running file to the dash

    If you open up the USM is there 12v/5v on the relevant terminal?

    If you have 12/5v then at least power is being supplied over the VNet. If no 12/5v then the issue would be in the VNet cable.

    If you have 12/5v then is the sensor reporting a voltage back, again this can be tested at the terminal strip inside the USM.

    The 12v and 5v pins have power
    so do the sensor wires
    So the USM isnt reporting back to the Dash?

    Correct me if im wrong
    If the 12v signal is at the USM then the V Net cable is working
    and if the USM has power and sensor values but the dash show nothing then the USM is faulty?
