strange vin#
I just bought a used 01 duramax/ally
when i try to connect to the truck it gives a message about the VIN#
and then says manufactuer Obdii paremeters have not been loaded:nixweiss:
i tried a couple different ways to enter the proper VIN# with no luck
when i connect to the truck it wont log properly?
i have not tried to read the ECM or flash it yet, should i ?
ive added 2 screenshots i hope you can see them
thanks
-
here is the Vin# U=U3/4?HU"a"
And i also have the security light on the dash that will not go away?
im not sure if this is related
-
It may have a tune in it from another company. I have seen that before on a Westers tune.
-
thanks guy
i have never heard or read about anyone haveing this before
but i was kinda thinking the same thing..the person whom i purchased the truck from said it wasnt tuned?
i can see what the op system is,So do you think i just try flashin a known stock tune in or try to read the tune?
-
-
I agree, make a copy and then flash something new in.
If you need a copy of the stock tune for that truck, PM me the VIN # and I'll get you fixed up.
-
well its LOCKED! looks like ill need a new ECM
here i thought i bought a virgin
-
I can see why people might lock a PCM but is there any kind of edicate or standard operating proceedure so that we don't lock these down and render them useless? What is the norm?:notacrook:
