Hi Scanner Danner! This is this first video I have watched of yours in a while I am ASE Certified in the Electrical Systems of Automobiles, and the way you teach this stuff is so much better then the way my teacher taught this back in college, I love how you go into depth for each step of the process, I am more of a hands on learner, I honestly wish you were my teacher for it when I was in college, I love the video! I am will be subscribing to see more videos of yours!

I'm sixty two years old. I graduated from automotive school in 2000 and worked in the field for about three years before I moved to Mexico. Some years back I returned to the U.S. and discovered you on KZbin. I want to thank you for re kindling my passion to work on cars. The other day I took out my scanner, voltmeter and my Sun scope to trouble shoot a TPS problem on my sons truck. It felt like old times.It is great to see you work with your sons. You are a good teacher with a lot of patience. God bless the Danner family!

[@wyattoneable]

I've always enjoyed the detail that you put into your videos. The picture in picture and references to your book keep me involved. There are times I can't watch a video in it's entirety but not here. It was worth the 49 minutes and now can't wait for part two.

As a fellow Celica owner, the thorough explanation of how the igniter works with the coil was very interesting! Always wondered how you would diagnose a bad unit! Good info 🖒

[@mostlymoparih5682]

One of the things that I love about your videos is you always hammer home the basics such as safety. Years ago my sister couldn't get my dad's International Travelall started. (hey I did say years ago) So I went and looked at it. I took a screwdriver with me under the vehicle and got it to not only crank over but start. I got out from under the car very quickly as it was still in drive. I was lucky that I was very thin at the time and could get out. If I had been a little bigger I would probably have been run over. Safety first and thanks for the reminders.

[@mostlymoparih5682]

As always learned something I didnt know. Gotta say its why I've been watching for so many years. Thanks Danner!

[@nandor690]

I have never said to myself “you know, that Danner talks way to much”. I find that pretty much everything you say is informative. Even if you’re going over it for the third time. Sometimes I need that third time to finally be like, ohhh i got it now, that’s how that works. Plus it’s cool to see your son catching on too. I hope my son that is soon to be born will like learning this stuff from me

[@ScannerDanner]

Thanks so much. There are others who feel differently and even commented so in this video but it's comments like yours that remind me to just keep doing my thing. I realize it's not for everyone and that is okay.

[@michaelmayer8753]

scanner danner, you are THE MAN! I have not found any other information on the web/youtube that has been as thorough and helpful as your videos. You have helped me drastically with the diagnosis of my ignition system. I have a 93 4runner with the 3VZE and was getting very stressed out when diagnosing the issue. There is very minimal information related to the 2nd generation 4runner, when it comes to diagnosing, calibrating, and understanding the various components that love to break on this pain in the neck engine. I plan on making some how to videos regarding TPS calibrating and Ignitor diagnosing for the 3VZE. I wanted to show the process of using a test light on the IGT circuit to verify spark at the coil, thus eliminating the condemning of various components that seem to always get replaced leading to no outcome. I of course would give the credit where its due and state all of the information was obtained from your channel. I just wanted to say thank you, and you have helped out many of us 4runner owners who felt left in the dark when it came to ignition gremlins. I am not joking when I say the literal test procedure in the Toyota WorkShopManual for the ignitor is to, "Try another Ignitor."

[@spelunkerd]

At first I was scratching my head when I saw you reach for fuel injectors when you knew it was a spark problem. Of course you were thinking ahead to the next question, the question of whether you had cam and crank signals. It's so much easier to test at the injectors rather than hunting for notoriously difficult cam/crank sensors, and you wanted to prove the slight movement of the tach was not mechanical vibration from the moving engine. By proving injectors were working you proved that cam and crank signals are fine, cutting your work load in half.

[@ScannerDanner]

Exactly my friend. I had proof the inputs were good, just wanted one more rock solid piece of evidence that it was time to move away from them.

The NE signal indicates crankshaft position and engine RPM. The G signal (also called VVT signal) provides cylinder identification. By comparing the G signal to the NE signal, the ECM is able to identify the cylinder on compression.14/09/2022 NE Signal and G Signal - Toyota Engine Control Systems

Toyota Distributor and DLI Ignition Systems - explanation and guide Toyota Single Coil and Distributor Ignition Systems, with computer controlled advance and 5-pin ignition systems So here is a quick little explanation of Toyota ignition system Ignition System Overview This is basically the breakdown of the most common of toyota's ignition systems, where ignition timing is controlled by the ECU and the ignition system comprises of a single coil and distributor. In short, what happens is the dissy is obviously spinning with engine RPM, and generating the variable reluctance (VR) signals "G1" and "Ne". Ne is the cam position signal from the multi-tooth wheel, giving the ECU the exact rotational position of the engine within it's cycle. G1 is a reference signal that the ECU can use to determine what cylinder the engine is up to. The ECU reads these signals, then applies it's ignition advance according to its programmed ignition map, and sends the IGt signal out to the Ignitor. The ignitor fires the ignition coil according to the IGt signal. The ignitor also generates a return signal to the ECU - IGf - to let the ECU know that the ignition event was sucessful. Pretty simple really.

[@boboften9952]

Toyota Distributor and DLI Ignition Systems - explanation and guide Toyota Single Coil and Distributor Ignition Systems, with computer controlled advance and 5-pin ignitor The most common stumbling block people come across with wiring up an engine conversion is the ignition system. Often a second hand loom is used or you are making a loom from scratch, and when you get to the ignition system - you can't for the life of you match up what the fudge is what! So here is a quick little explanation of Toyota ignition system and 5-Pin ignitors that should answer most questions about them. Ignition System Overview This is basically the breakdown of the most common of toyota's ignition systems, where ignition timing is controlled by the ECU and the ignition system comprises of a single coil and distributor. In short, what happens is the dissy is obviously spinning with engine RPM, and generating the variable reluctance (VR) signals "G1" and "Ne". Ne is the cam position signal from the multi-tooth wheel, giving the ECU the exact rotational position of the engine within it's cycle. G1 is a reference signal that the ECU can use to determine what cylinder the engine is up to. The ECU reads these signals, then applies it's ignition advance according to its programmed ignition map, and sends the IGt signal out to the Ignitor. The ignitor fires the ignition coil according to the IGt signal. The ignitor also generates a return signal to the ECU - IGf - to let the ECU know that the ignition event was sucessful. Pretty simple really. So how does one wire up the 5 pin ignitor? The really annoying part about wiring up a conversion, is a majority of Toyota 5 pin ignitors after 1989 have the plug as part of the housing - meaning there are no wire colours to go by. This is quite the PAIN. So here are the pinouts, and most comon wiring colours. Note that the metal case is the earth for the ignitor, so make sure it is bolted to metal (the stock brackets usually provide this earth) 1/ B-R: Coil Negative (output) 2/ B: Tacho signal (output) 3/ B-O: Ignition power (12V+) 4/ W: IGt (input) 5/ W-R: IGf (output) How does one wire this all up with an aftermarket ECU? Well - this is easy! Most of you would be using a Microtech/EMS/etc etc which are all quite capable of using the stock signals and ignition system. Here is the way most of these will hook up to this type of Toyota ignition system..... Most aftermarket ECUs want both a "cam position trigger" and a "reference trigger". The Toyota dissy in this system provides these triggers with a VR (variable reluctance) signal with a falling edge trigger. This "falling edge" part is important, because the ECU needs to have the signal go a particular way for the internal circuitry to detect the very low AC voltage from the VR signal and interpret that as a trigger event. Some aftermarket ECUs allow you to select a falling edge or rising edge trigger through it's programming software, but some want the signal to be one or the other without the option of change.
