    My apologies on the Part 1 video already being available here from 2019. I did not realize I used part of this series in the past to promote SD Premium. Anyway, here is part 2 of 3. I will have part 3 up this Saturday at noon (10-22-22). Premium members, you will find this series in my "No Start Case Studies" playlist right here www.scannerdanner.com/scannerdanner-premium-chapters/no-start-case-studies.html
    For you guys that are not SD Premium members yet, you can sign up for a 14 day free trial and then immediately cancel your subscription and you will still get the remainder of the 14 days without worrying about being charged the $11 for the next month. But seriously, where are you going to get this type of training for $11 a month? No where! Hope to see you guys there. Think of it as channel support for us here on UA-cam, with a serious benefit to you! We have over 400 hours (500+ videos) of training material and counting!

    Paul, the European car makers do explain what each wire does or where it goes to in a control module in their OEM electrical wiring diagrams, for example WIS for Mercedes Benz. It’s the shitty all in one websites like the Mitchell websites you’re using for diagrams that doesn’t explain it. It’s really not a Euro car issue, but rather an American wiring diagram supplier issue. As always love your teaching.

    We definitely need more mechanics. I got sick of arguing with other "mechanics" about parts changing or not knowing the difference between tapping and knocking. It was always something stupid, useless and/or dangerous. Even had a tech open a trans cause the shifter was stuck in park...of course the cable was torn and seized. I guit every shop and packed up my tools each time. Eventually opened my own 👍🏾. I've followed you for years and love the passion and knowledge, thank you.

    And I thought I was going crazy! Thank God you guys were working on a VW. The diagrams really suck! Even the OEM ones do. It's not Mitchell or Identifix screwing up. I actually had to take one of the connectors apart (t91, the one with the Power and Ground connectors). Everything except for the Power and Grounds is wrong. Color-wise and cable-wise. 97 and 80 are supposed to be Can-H and CAN-L. There are no cables in those two holes.

    More than a couple times I've seen shorted 5 volt reference circuits. I just knew the ECU was smoked. It's never happened yet and I don't know how it survives. I guess I just played it off to an ECU that either has very robust converter circuitry or a resistor that is also able to handle it. I'm not an electrical engineer by any means so I don't really know the answer.

    Although you live in the US, I would like your take on the European Fiat Stilo 1.6 Marelli IAW 5NF ECU issues. Is it possible that a bad FBW electronic throttle body could damage the 5V circuitry on the ECU? Most people would just blame bad placing of the ECU on top of the engine head that would cause the ECU to get hot. But some people replaced their ECUs only for them to fail after 2 years or so again.

    • @ScannerDanner
      @ScannerDanner  Рік тому

      Usually the 5v ref circuit is highly protected from shorts. Take the short away and the 5v ref returns to normal. So are you saying that the 5v ref circuit is being shorted by the TPS circuit in the throttle body?

      @xynostasos9022 Рік тому
