I've searched all over the forums and internet looking for the pin layout on resetting the airbag light by jumping the tc and i think ab pins to ground. people say it's under the hood, i couldn't locate the dlc3 i think it's called? i'm also told that it's the obd2? but what pins do i ground? i have a 03 is300 with e-shift auto tranny. please somebody, if you can help with a detailed description or with a picture pointing it out, i would be forever grateful. thank you.
