    Default FlashScan V2 will not comm with PCM

    OK, I have 12v to the interface, because plugged into the ALDL, the screen lights up. This is without it being plugged into the USB. When I have it plugged into the USB, and I disconnect and reconnect to the ALDL, I get the "da-dink!" tone. But, when I try to read or write, no go. The lights flash on the interface, and it goes through the motions, but I get the "getting status" countdown to 10, and then STATUS:UNKNOWN and then a dialog box that says "connection to PCM has been lost".

    I can flash it with my TECH2. I can read and write to it with my other softwares.

    Is there any self diagnostics I can do? Any way to check the interface, and verify it's just the cable?

    TIA.

    Hi Ed,

    I pm'd Tech Support.

    I take it you're attempting to read/write from the V2 keypad/LCD.

    In the meantime:
    - what V2 firmware is installed...?
    - which PCM(s)...?

    Thanks.

    Hey Joe, I'm trying to flash from the laptop.

    Version 7.5.7 (Build 178)

    It's a 411 PCM on the bench. This is the first time in a few months I'm using my EFIlive, and last time it worked fine, now it won't. :shrug:

    Quick shoutout to Ira. He sent me a new cable, and new ethernet socket for the interface. Cable didn't fix it, but I replaced the ethernet socket, and all is good!!

    Thanks again Ira!!
