FOR THE AVERAGE TECHNICIAN / MECHANIC A CAN PROBLEM CAN BE VERY STRESSING ESPECIALLY WITH NO TRAINING . ONLY SAYING GOING FOR THE FIVE VOLT REFERENCE SIGNAL WOULD OF MOST LIKELY BEEN AN EXPERIENCED TECH MOVE . THANK YOU FOR YOUR TIME LOOKING FORWARD TO LEARNING MUCH MORE !
I suggest doing a capacitive discharge of the car battery before changing out parts. Disconnect both battery terminals, starting with the ground - (negative), connect both connection leads with a jumper wire for at 1 minute. Reconnect both battery terminals, hopefully that helps. That worked with my car!
Clean contact connections on battery terminals or maybe check your fuses… if not then it might be ripped cable…. But I’d check fuses and battery terminals
Hi just checked the fuses as the cigarette lighter socket not working . Now lights appear on dash but vw touran 2010 wont start ( crank over) Please whats the fix ?
got no computer to check things. Working outside in mud and cold so hoping to narrow down fast....... Have similar issues 2003 beetle TDI out of the blue no crank. What other fusees may cause this 5v no reference. Did I hear right, the one he found bad in this one was Fan? What fan? Engine fans or heater fans?
@@TL.... turned out to be the wire to starter. the one the ignition switch triggers to activate starter. It connects the solenoid on top with a large black plastic plug. On mine a single wire. The wire brake away under some tape from previous owners past repair on the same wire. Hope that helps you. ps- had to remove battery and tray .... only then did the issue become discoverable.
@@coachgeo i have an 01 jetta and on my fuse box on the left side of the steering wheel, fuse number 28 which is supposed to be for the fuel pump, according to the diagrams, there is no fuse there, and when testing for power it shows none as if theres no wires in the back that would normally go to a fuse , is this normal ?
@@TL.... find a diagram that has more detail... such as in a more detailed description it may say.. "except in diesel models" etc. it may be that the diesel model may not use a pump in the tank. Plenty diesel vehicles do not have electric fuel pumps so that may be the case.
I'm not quite sure what you mean. No 5v ref does not necessarily mean the ecu is faulty many things can cause it like in this case the broken wire popped a fuse.
ua-cam.com/video/0PFfp_3NF1o/v-deo.html 1:44 What is the point of 5 v check if you are going to check the fuses anyway ,no matter what the result is .Sorry if I look too picky ,but I think that logical process to the fault and cause of fault to be short ,fast and clear as possible.You ve missed one step from a perfect video , no big deal :)
@@soptea he wouldn't have to check the fuse if he had the 5 volts and if he didn't have the bad fuse after not having the 5 volts he would have to check the ecu .
Help needed. Last night parked my VW golf as normal. This morning, remote won't open doors, but hear click noise. Changed remote battery, still nothing. I manually open car door using key and try to start but no power, no lights on dash and radio, no power completely, total no sign of life. Please help advise needed
Nice find there with your methodical testing. Thanks mate

Thank you for your comment. I have been stung in the past panicking why the scan tool wouldn't comm. 5v ref is very quick but essential check
Well explained for the less technical to follow,great find and fix ,thank you for sharing
Lol. What fuse did you pull out? What’s is related to? Lack of info here
5v can
What a fantastic and practical video. really well done and thank you for the help.
Glad you enjoyed it!
Top work specially coming in to help out the community mate ... Great thought process thumbs up from me 🤗👍👍👍👍

Well done good diag process thanks sharing and good on ya coming out to a help people at such a worrying time.
Thank you for watching
The Actual Air mass has a % percentage sign after it LOOK - and it’s at 100%. The requested isn’t a percentage - they aren’t supposed to be the same!!
Good job pal
Thank you
I have mk5 golf tdi and when I am driving it will cut out then it starts up again after 10 minutes but it happens quite often
Clean contact connections on battery terminals or maybe check your fuses… if not then it might be ripped cable…. But I’d check fuses and battery terminals
Great diagnostics there, nice find mate
Thank-you
Great job buddy, sometimes simple is better 👍. Stay safe.
Thank you. Stay safe buddy
Top job. Done your bit 👍
What is the blown fuse 22 for ? Ignition related?
Hi just checked the fuses as the cigarette lighter socket not working . Now lights appear on dash but vw touran 2010 wont start ( crank over)
Please whats the fix ?
Just subbed mate great video
My van did the same today would not start and then it started what could that be
Probably a fuse that’s about to blow faulty fuse
Unless it’s a loose battery cable or just too much corrosion

@@coachgeo the solenoid to starter wire? Or the battery to solenoid wire? Or the ignition switch wire?
Spot on!
👍👍👍

Is that 5 volts reference check 100 % equal to good/ bad ECU supply check ?
