Looks like you have TCM selected and not ECM in the flash menu.....

 

[MMLMM]

Edit, just realized you said your were trying to read TCM at the bottom....



Do this...shut key off, unplug everything, close out of efi.

plug v2 into usb on pc
wait until v2 starts up and there is the menu
plug into truck
turn truck to run
double click the tune file and efi opens
go up and hit the red arrow

Id OS numbers are the same, hit the skinny red arrow, if the os #'s are different, hit the fat red arrow (only if the tune is for your truck...)

 

[kman2468]

well i am just trying anything to connect to my ECM i am making sure my V2 was ok by trying to read files
i was trying to load my tune and it came up with error check cables and all that

and i checked my new tunes they were both the same OS unless my tune now that is on my truck is a diff OS it will not connect to my truck tho im hoping im not confusing u

 

[kman2468]

ok well i honestly dont know what to do now....
tried it again and it wont work..this is frustrating

 

[kman2468]

ok so when i tried to connect to ECM it says status unknown
and chase is looking at my stock tune and it says status unknown what does this mean????????

 

[racinmike77]

happened to me last week, I did what mike said.

Removed efi completely, started the truck to make sure it wasnt screwed, then I plugged everything back in selected the calibration I wanted to load, selected LLY ECM and it flashed fine

 

[kman2468]

i did what mike said and it wont work..this is frustrating guys lol ikd what to do!1

Maybe there is something with your aftermarket stereo messing with it. Even though you pulled the fuse. I have heard of that happening before. Since the stereo was added since the last time you have flashed your truck.

 

[kman2468]

How do I fix it? Is there anything I can do? And I tried the scan tool and it connected so it's weird

 

[kman2468]

What if I completly unplug my radio put my stock one back in and then turn truck to stock then read it?

 

[MMLMM]

What if I completly unplug my radio put my stock one back in and then turn truck to stock then read it?

wait, are you trying to read a dsp tune out of your truck? or any non stock tune for that matter? Can you flash a tune in (I see that your suggesting put it back to stock).

 

[kman2468]

I haven't tried flashing the tune since I tried first time I'm just trying to read my tune out of the truck to see if it is connecting to ECM would flashing a tune be diff then reading a tune in a way of connecting to ECM? I tried scan tool and that connected so idk why it won't connect when I'm trying to read. and I don't think this tune is a diff OS it is jus my street tune from u I'm worried about frying my ECM that's why I'm just reading tunes or trying to

 

[kman2468]

i probabl sound like an idiot trying to describe this lol

 

[racinmike77]

Does the truck still run?

Click on the status button and get a status check and you can also try running a test.

 

[kman2468]

yes truck runs i do a status test and it comes one with status unknown

I had this happen once on a lbz. I ended up taking the battery cable off for a while and restarting my computer and then it worked. I don't know if that was the right thing to do or if it was just coincidence but it worked and I was getting desperate

 

[kman2468]

Well I was told to unhook my batteries also but I haven't yet

 

[MMLMM]

Try un hooking the batteries for a bit.
Also can you just un plug the stereo?
You don't have an alarm do you?
Nothing plugged into the cog lighter?
Nothing wired in right at the obd port?
Can you measure voltage at obd port?
How many volts at battery when flashing?
Is the onstar fuse pulled (wonder if its wigging out now that you don't have factory deck)

i will try batteries today
i can easily unplug the streo i was going to try that first
i do not have an alarm
nothing is plugged in
there is nothing wired into to OBD port
how do i measure volate at obd port?
how do i check how many volts are at my battery when im flashing a tune?
i do not have onstar


a couple people were thinking my radio is drawing the power from the ECM so if that is the fact and i pull my radio and it works...will my dsp nto work? or does it not draw that much power? if the radio is taking it from the ecm i would figure my dsp wouldnt work then either
