    Default trouble reading pids

    hi my brothers truck pcm can be read and tuned but not scanned...

    i have 2 other trucks that scan no problem

    with the v2 attached to the odb 2 and the v2 connected to my laptop i enter the vin in the scan tool select the engine size also....
    so far so good! the pids have no x through them and appear to be supported!

    now i click connect, yellow button in the scan tool

    only 3 pids are valid ... the rest have a red x and there is no data from any selected or valid pids

    Post screenshots of these tabs from scantool right when the connections fails: Console, OBDII->Summary, OBDII->Modules, OBDII->Controller, PIDs.

    I have recently ran into the same problem with my 2000 Corvette. 2004 Escalade worked fine but the Corvette would only report Air Mass Per Cylinder, Injector Duty Cycle Bank 1, Injector Duty Cycle Bank 2, and Power At Wheels. However, nothing would record when the red or yellow bttons were activated.

    Console
    10:54:56.666: EFILive V7.5 Version V7.5.7 (Build 283)
    10:55:08.007: No interface cable found.

    In scantool, go Edit->Properties->Connection and set Preferred Cable Type to EFILive FlashScan V2.5 HAPI, and click Ok.

    Just check my scantool. It was already set to the V2.5 HAPI. Problem still exists when I loaded the Imperial PID selection, only three were reported and all the other were non reporting with the RED X. Ran the DTC and have U1096, U1064 and U1016 H codes. Somehow the OBD II connection is not being recognized by EFILive V2, yet it will power up the V2 FlashScan.

    After trying to log data, select the menu option: File->Generate error report, send the error report to me at paul@efilive.com, include a link to this thread so I know what its about. I'll see if I can determine what has gone wrong.

    Regards
