    A problem with an automotive trouble codes diagnosis device

    Hello Everyone !
    glad to be right here posting my ever first thread in this forum and I hope You all to be in a good wellness
    So first of all, a couple of months ago I've purchased my father a DTC (diagnosis of trouble codes) device for Automotive that's known to be really handy despite being a chinese clone of a genuine unit known as Actia basic Passthru XS and I wanna say that I had it flawed since then and the following video shows my suffering with it : https://www.youtube.com/watch?v=JYkhgXAk_v4

    It worths metioning that I've done a dump for a hex file for a pic12f629 chip on the upper board thinking that it didn't have anything written on it but it was fine and undamaged unlike a thought.

    If You have any idea of the reason behind such an issue then please illuminate my sight !

          Ok, I apologize for not knowing much about proper sites for photos exhibition, I've been using imageshack for a little while and the trial period was finished, the photos below show the pcb of a device like mine.

              To me that OBDII reader does not want to talk to your computer. Not sure why... could be a wrong setting in the device manager. You could check with an oscilloscope if you see data in and out of the usb bridge on the OBDII reader. Check if the reader powers on etc.

                  could be a usb com-port.
                  if it is, you need to use the right drivers sometimes - as in old ones.
                  the latest drivers fuck around if they think the chip is a clone.

                      I got it, I wanna thank You for giving me an advice on this but regarding the oscillator I don't actually have it and I don't know someone of mine to have it either !
                      it worths mentioning that I've tried many many times to install a variety of drivers versions for this unit and I was ended up with the same result, but there's a video of the correct installation instructions which I've followed a letter by letter https://www.youtube.com/watch?v=cw049QOIlTY
                      and tried it on win 7 and xp with no changes at all as I mentioned earlier in the video.

                          I did so with no changes at all !
                          the earlier version of the driver was known as (3.07w) and I already installed it with no luck with any changes.

                              what happens when you plug it into a car ?

                                  Watch the video I posted in the thread above, please.
                                  Whenever I plug it I get a driver installation wizard and I get through it with no issues then the driver show up in the device managaer with no issues either, but when testing it shows no communication, response between the vehicle and the laptop again watch the video above.

                                          Such a thing was kept in mind with the same crappy results.

                                                  i still suspect the driver, that 20pin chip could be a FTDI chip - or a clone of one.

                                                      neither are like yours inside will all those relays . i wonder why it has them all ?

                                                          that's probably for routing the can from primary to secondary and creating a break - it's called a passthou so i assume it does a man-in-the-middle type trick.

                                                                      Well, the fact it's a clone of the Acita Passthru basic XS which has a din 8 cable for a choice of either a RS232 or USB cables, whereas the clone one has only a usb inlet.
                                                                      as shown in the pics below we have the genuine VCI on the right and on the left side the clone.

                                                                                  In the last ~3-4 months I have been having some issues.
                                                                                  1. Problem: It started with random picture disappearing (sound still worked).
                                                                                    Frequency: Happened about once a week.
                                                                                    Solution: Had to turn off TV wait a few seconds before turning it on again.
                                                                                  2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                                                                                    Frequency: Happened about once a week.
                                                                                    Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.

After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

Check continuity between the ZIF connector from the keyboard to the KBC and all pins are correct. I cleaned the ZIF connector and the KBC and I still have the same problem. I reinstalled windows just in case, and it didn't work. I updated the BIOS to the latest version A16 and there were no changes.
