Authentication Code

[Blacky]

Often when customers enquire about PCM/VIN licenses on their FlashScan cables, EFILive support require two pieces of information: The FlashScan Serial Number and the FlashScan Authentication Code. Here's how to find them:
Connect FlashScan to the PC.
Run the Tuning Tool Software.
Select the menu option:
Help->FlashScan V1 PCM licensing
or
Help->FlashScan V2 VIN licensingPlease note, the Authantication Code is not the same thing as the Registration Key. The Authentication code contains 3 segments, the Registration Key (printed on the Blue license card) contains 4 segments.

The Authentication code will be updated each time a new PCM/VIN license is added. Actually as noted by some customers, the Authentication code is a rolling code and also changes each time the EFILive software is restarted.

See attached image for example.

I can't get my authentication code

Did you do what the message suggested, and download and install the latest software and firmware?

Download the latest V7 and V8 software here:
http://www.efilive.com/latest/cat/download-efilive

You must download and install both V7.5 and V8.
Then once V8 is installed, run the "EFILive V8 Scan and Tune" software and click on the [Check Firmware] button to update the firmware.

Am I able to purchase a new vin license with a previously purchased auth code? I ask this because the the option to reorder is on my account dashboard... 18629

Yes, we do that often.

Thanks! I ended up just going for it and it worked for me, but thanks for the reply! I'm not sure why I hadn't ever noticed that option before, but I'm glad to see that it's there.... That's a timesaver

I can't get my code. I reinstalled 7.5 and 8 from the site, hooked up v2, ran scan/tune tool and clicked on license and I get this error

"No device connected. Please connect a flash scan or auto cal device."

No other program is running. V2 screen is lit up and says connected to PC.

The message "Connected to PC" makes me think the firmware in your V2 is very old. Can you check the firmware version in your V2 using the V2's on screen menus. The firmware version needs to be V2.07.xx or later.

How do I update firmware if I can not connect?

Ok, very carefully read this, do not proceed until you understand this doc:

[bubba68ss]

Ok, I now have boot block 2.07.07 and firmware 2.07.82.

Thanks

Hey guys, i'm experimenting communication problems between my flashscan V2 and my laptop... (no interface cable found) I'm getting pretty frustrated as everything was working just fine minutes before everything froze up. Flashscan device is communicating just fine with vehicle through obd11 port, and powering up from my laptop when unplugged from obd11 port, so i believe the cables are fine (i always baby them) I've been trying everything i could think of for 6 hours now to resolve the problem and still no go! I'm at the point where i'm trying to update the firmware but even with the Flashscan box in dead pole EFILive explorer wont enable the program button to let me reprogram it. I'm at loss right now, please somebody help me :crash: Actual firmware version is 2.07.35, and Boot Block 2.07.04 Thanks everyone.

[Blacky]

The first thing you need to do is to get the correct firmware back into it so that you can update the boot block to V2.07.007

Download and install the latest V8 software available here: http://www.efilive.com/latest/cat/download-efilive

Run the EFILive V8 Scan and Tune software and click on the [Check Firmware] button. You should get an option to [Update Firmware].

Once updated, you should then update the boot block to V2.07.007. After updating the boot block you'll have to re-update the firmware again because the when the boot block is updated it deletes the firmware.

Hi Paul, thanks for your quick response. I didn't get to read it until now as i may be on a different time zone (Canada). I read pretty much everything i could find on this forum to get to fix the problem, and it all seems to lead to updating Boot block and Firmware. So that's what i've been trying to do for hours now with no results as V7.5 and V8 dont get to ''see'' my Flashscan anymore.

I even installed EFILIVE on a different laptop thinking maybe there was something wrong with the communication ports on my old one, but still no go.

I dont think there's anything wrong with the Flashscan v2 as it really doesnt have a lot of runtime on it and it take so much care of it, like new really... It did connect with the vehicle i was working on a minute before something went wrong. I got out of the truck to lock all doors before going for a test drive, but when i came back into the vehicle, could not get communication with the device, and never did after.

I checked all the wiring and its good, Flashscan will power up and communicate with vehicle through OBD11, and will also power up though usb cable but wont communicate with laptop.

From there, i really dont see how i will get to re establish a communication channel between them.

I really appreciate any bit of help, Thanks. Jim

Thanks for your input 1FastBrick!

Unfortunately i did swap the usb cable no result, obd11 cable no result, different usb port on my laptop no result, loaded efilive on different laptop no result, attempted no update boot block and firmware no sucess...

Reading though all related stuff, i came to realize that the Flashscan should never be powered from two different cable to the vehicule at any moment. When i bought my flashscan, i assume i read that orange notice inside the box saying never use an inverter to power your laptop, which is probably the reason why i went and bought one of those 12 volt laptop chargers thinking it was all right, but it was NOT! Still, its been working just fine for six years but suddenly came to a stop...

So my advice to everyone on this forum: DO NOT EVER USE A 12 VOLT LAPTOP CHARGER WHILE YOUR FLASHSCAN IS CONNECTED TO THE VEHICLE! At any time you do so you're playing with your luck.

I sent my Flashscan to SoCal Diesel for repair 5 weeks ago, still waiting for an estimate...
