Where do you find those pin wire remover unlocking key tools and the name their known as ? I have Audi Q7 3.6L engine and I'm working on it myself. I also would like to know how do you or can we use our VCDS software to perform the ECU diagnostic test on it if so how do I carry it out step by step thank you.

Hi. We're glad you enjoyed the video! The terminal tension/pin tension tools can be hard to come by. Some suppliers sell these specific tools: www.autotechelectrical.com/ but if you are unable to source these, then a good alternative is getting terminal test lead attachments for your multimeter which will do the same job: www.hubitools.com/en/catalog/diagnostic-test-lead-set~0389d3b3-3acb-2bce-9ac0-39eabe1ce34f However these usually come in big kits which makes them fairly expensive. Finally, if those two options aren't for you, you can always buy replacement terminals/pins for the specific connector you're testing and use those! Hope that helps.

@Ecutestinglimited

Hi. Yes, if you remove the affected wire's terminals (de-pin) from both connectors then the wire should be isolated from the circuit. Plug both connectors back in and test for continuity between battery ground or battery voltage depending on which you suspect it is shorted to. Hope that makes sense!

Hi i dont get the voltage drop test .You say to test from end to end will a multi meter pick this up without being connect to the negative?

@Ecutestinglimited

4 ай бұрын

Hi, very good question! Yes the multimeter will produce a reading even without being directly connected to a negative. This is because in order for current to flow through the wire, the circuit must be complete by being connected to a ground point. While you're not directly touching a ground point with your multimeter probes, the circuit itself is grounded through its connection to the battery's negative terminal or another grounding point. This shared ground ensures that all components in the circuit have a common reference point for electrical potential. By placing one probe at the start of the wire (or one side of the component) and the other probe at the end (or the other side), you're measuring the voltage difference between these two points. This difference is the voltage drop, which occurs due to resistance in the wire or component. The multimeter doesn't need to "know" they share the same ground in an explicit sense; it simply measures the difference in electrical potential between the two points you're testing. In the video, we have shown a simplified wiring diagram only showing the 12v power supply wire to the alternator, whereas for this circuit to be complete there would also be a ground wire going back to battery negative or a ground point on the vehicle (in most alternators this would be the casing of the alternator itself which is attached to the chassis). Hope this helps!

You can carry out the testing methods highlighted in this video using either an analogue or digital multimeter. However, a digital meter is always preferable as it offers more precision and reliability in results, especially when testing circuits dynamically such as during voltage drop testing. Also keep in mind that with analogue multimeters you will need to select the correct range when carrying out your tests to prevent damage to the multimeter. Hope this helps!

Hi. We have actually recently completed a video on diagnosing CAN bus faults here: kzread.info/dash/bejne/mI6BsNyEoKatlsY.html The video goes over some basic principles of the CAN bus network, however, as your system includes a gateway module, the diagnostic tests at the OBD2 port may not be the same. The fault will likely lie with either the gateway module or the alternator (generator), so you will need to unplug the alternator to see if the fault disappears. If it doesn't, then test the integrity of the communication wires between the two. Finally check the gateway module's power (sometimes fused) and grounds. Hope this helps!

That indicates the alternator is faulty. We have done a video on diagnosing faults with the alternator here: kzread.info/dash/bejne/maR6zrKOYqu3m7w.html but as you have said, it is likely a fault with the voltage regulator. Depending on the model of alternator you have, the regulator can be replaced without needing to replace the whole alternator, however we would recommend getting this confirmed by a qualified mechanic who can advise you on your specific vehicle.

I was told a while ago that a lot of modern computer controlled cars have resistive cables ! So I'd assume that if you have to re solder a cable, the pc controller would know this and still flag up a fault ? Apparently.

@Ecutestinglimited

4 ай бұрын

Modern vehicles can use a variety of cable types, however resistive types are normally for specialised components and the majority of the vehicle's electrical system uses standard copper wiring in which a properly soldered joint shouldn't cause any problems. However, it is always worth consulting your vehicles repair manual or schematic to ensure you are following their guidelines.

Hello, after longtime....😊 Here, 12V Vs 7V... I have one Super CONFUSING VOLTAGES READINGS on door opened or closed status. For example, in i20 2011 India version without LCD display on instrument cluster, the voltage at any door switch is SOLID 12V when door is closed, and immediately drops to SOLID 0V when it is opened. Now, in today's modern car like Toyota Glanza and Toyata Taisor which has LCD display, and for the same situation, when door is closed from opened, the voltage remains at solid 12V, and after about 20 secs, the voltage drops to SOLID 7V. As soon as door is opened, it changes to 0V. Now, when the door is closed again from opened, the voltage immediately rises to SOLID 12V, and stays for about 20 seconds, and then only drops to 7V. Now, why is this voltage drops delaying from 12 to 7?? What's the purpose or significance of this delay in voltage drops? Why not immediately changed to 12V from 0? Why 12V, and then later slowly to 7V???

Modern car wiring is absolutely crap. The computer systems are quite useless as they cannot tell you exactly what is wrong. Modules running various parts of the car should not need more than 4 wires for communication, this was supposed to be a bus system but instead there are bundles of wires going everywhere

Soldering is forbidden in automotive wiring repair!
