My experience with a laptop GT1

[SlickGT1]

Ok guys I need help. Something is up with my car / gt1 (twins). So first off, I used the gt1 last week when doing the trans pan drop. Everything went great. I decided to use it yesterday to see if any of the previous codes came back. Now nothing changed in the car or laptop.

So I connect it yesterday and get some weird shit. Before, the car would get recognized automatically. I didn't have to do anything. This is the message I get.

IDENT_E53 / Message 1a
No data could be determined from the vehicle. automatic vehicle identification cannot proceed.

This may be due to the following causes.
-Unknown model variant
-Diagnosis bus faulty
-EWS defective
-EWS replaced and not encoded

Continue with manual identification.

So I go to manual identification, run a quick test, and nothing comes up. I tried restarting it all.

Computer, the connection bars light up. The yellow head, green light and solid yellow light. Everything seems fine with pc. Only thing I can thing off is that some setting got reset as the computer laid unplugged for a week? I don't know that sounds stupid, but are there settings that I should check?

Back to the message I get.
-Unknown model variant, ok I get it, it can't detect car. It doesn't even want to connect.

-diagnosis bus faulty. WTF, the obi port? How is that even possible.

-EWS defective. What is this? Is this the security of the car? Everything seems to work fine. Lock unlock, start drive al the good stuff.

-EWS replaced and not encoded? WTFx2? I didn't replace anything.

So I also get a temporary disturbance in bus line message while trying to mess with other things in DIS.

What should I try? Should I try disconnecting the battery? Is there some ip issue with the DIS? How do I check IP in the DIS anyway?

Twins I hope you don't mind I'm going to give you a call today to pick your brain. I would be great to get this to work by the time my parts actually show up from ecst.

Thanks all in advance.

I would try disconnecting the head from the admin section of DIS and reconnecting it, and you can even test your connection to make sure DIS communicates with the yellow head.

Hi Neil, thanks. I actually do not understand what you mean. I guess there is an admin section in DIS. If I disconnect the head, is there something special I need to do to reconnect it?

What's the process for testing head communication? Those two signal strength bars on top right of the screen, I thought they represented connectivity and communication.

Twins suggested I try to have the car running to keep voltage up. I'm going to go give this a shot in about 15 min. I hope this does the trick. I'll post back shortly.

Thanks for the suggestions. Keep them coming if you can think of something else to try.

OK update, same thing with the car running. Auto detection does not work, same message, and manual doesn't do anything either. Fail Sauce.

I also figured out the admin part. Test the head, it said that its connected and communicating. IP is coo126 192.168.68.31. I also disconnected it, and reconnected successfully. So I don't think there is an issue with the gt1/DIS.

What should I try now? Should I bother disconnecting the battery and reconnecting it?

This may sound silly but make sure the OBD2 connector is in good shape and connected properly to the car, if all is good... I am stomped too..

Success.

Ok so here is the sequence tried today.

Connected the laptop to car via the obd connector while car was running (and off but key in position 2), and laptop was on. Fail

Connected to car via lan wire, while car was running (and off but key in position 2) and gt1 on, FAIL

GT1 turned on nothing pressed on screen.
Connect gt1 to car via the OBD connector.
Put car key in, not in any position, just the hole, don't turn.
Click Diagnosis in DIS
Screen goes blank and takes about a min
Message pops up that the there is a low voltage problem.
Turn key to position 2 (ignition), pop up box goes away by itself in about 20 seconds.
Message pops up saying that the car has been AUTO-DETECTED.
Click OK.

DIS FULLY FUNCTIONAL NOW. Thank you all. I'll keep you all posted if there are any other issues.

P.S. After this process, the GT1 seems to know the car, and disconnecting and reconnecting seems to be no problem, but this could be because there is some sort of memory in the program. My parts should be here Tuesday, so hopefully next weekend I will get to try this all again.

Ok so I was doing the trans drain and fill again. When I went to connect the GT1, it again would not connect for shit. 3 hours of messing around with it before I could do anything.

So here is what I came up with so far. I though the ODB2 port on the car was messed up. I decided to take that panel off, and pull the ODB plug out of the dash. Wires all look connected and in good order. Then all of a sudden, I see a resistor in the ODB port cover. It has 3 pins that connect to the ODB port when closed.

Anyone have any idea what that resistor is supposed to do?

Reason why I ask, is because I forgot to close that cover after last connecting the GT1. After 3 hours of messing around with the GT1, I closed that port. When I went to connect the GT1 after, I got a low voltage error, at this point, I started up the car, and the GT1 connected fine.

Is it possible that the resistor activates something in the port? So damn strange.

Going to try it again tonight. I actually killed my battery yesterday and don't want to run the car in the garage. So a friends booster is going to assist me today. I will let you guys know.

You are really good on hand. If me I do not what to do.

Um, I don't understand.

Got the GT1 connected again. Turned out my ODB2 plug on the car is the problem. If I push in harder, seems like it connects no problem. It just seems loose otherwise.

Are you running DIS on VMware or native?
