    Default Where does the pin 13 of U5 (74HC125) in carprog D1 goes?

    I have been updating and reworking my carprog, so far carprog + A9 pass the hw test, carprog + A1 pass the hw test, but carprog + D1 + A9 doesn't. But I noticed something, if I press really hard on the U5 (74HC125) chip of the D1 adapter, the test pass OK.

    So I tried resoldering, didn't work. So I desoldered it, and I noticed the pin 13 (I think its 13, it's marked on the attached photo), doesn't have any pad on the pcb, so the pin is not connected to anything. So I need to add a bridge to where this pin should connect, but I don't have my magnifier camera, and a magnifier glass is not enough for my eyesight to figure out where it goes.

    Can someone measure their D1 adapter and find a 0ohms point where I could connect the pin, and mark in the photo?

    I was checking the datasheet and it says pin 13 is "active low", so I connected it to pin 1 which is also "active low". Test pass OK now, but I tested it with a renault jaeger dash, and it says "no response from dash". Tried powering the dash with an external power supply, same shit. Getting really pissed at these chinese.
