    Default V2 not reading AD signal

    I just received my V2 a couple of weeks ago along with LM1 wideband. After spending hours trying to trouble shoot with AD calibrating and measuring output/input with a volt meter I finally checked the V2 and sure enough its not registering the raw data coming from the Wideband.

    Is there a fix for this?

    Ponch,

    Did you connect as follows:
    ADn+ = positive side of voltage trying to measure
    ADn- = negative side or common ground

    where n is one of 1,2,3,4.

    You can do a quick check of the A/D inputs by selecting the FlashScan options: F4->F4->F4 which will display the voltages form all 4 A/D inputs on the FlashScan screen.

    Then connect a 1.5V battery to any pair of +/- A/D inputs and see if the voltage is registered.

    It sounds like one or all of the A/Ds have failed. You should return it to the place of purchase for warranty/repair.
