Go to check the wiring diagram
VGS/VGS2/VGS3 NAG2 wiring diagram
this is the connections that we have to make between the transmission control unit and the obd cable that’s coming off the jbox on the im608 or the regular obd cable
As you see we have one power and one ground since we don’t have power and ground coming from anywhere
so i just decided to use this power pack or booster pack
i use the power and ground with it another leak coming to here
We’ve done the wiring
press Exit
we’re gonna go to read TCU data, Read the data save it. Then we’re going to go to renew TCU. It’s going to get a erase password off the internet.
Only password is the erasure password which is easily calculated by im608. No other password is required.
Then it will renew the whole transmission control unit, make it brand new since this one right now is a used one.
Read TCU data.
There’s all the data. As you see here it says yes yes no no and I’ve actually renewed it. Press OK it will save it.
