Key On, Fuse BLOWS!? (SI Ep 15.4)

[@tecnaman9097]

At that time of night after working all day i'd be too knackered to think straight. Kudos to the stamina of you guys, you are awesome.

[@wildeauto34]

Not only teaching but testing each other. You make it look easy. Great job.

[@kenandree7102]

Ivan, friends like those two are priceless! What one hell of a video youse guys could put out, especially if you could drag Eric O into too! Hey, new channel, stump the tech! Lol

[@themalewhale59]

Every day is a school day. Impressive diag when faced with 2 guys that have already found the problem. Big balls to tackle that on camera. Respect.

[@billyyoder8171]

Thank you Ivan, Steve, and Keith. Good job. Have a blessed and safe week.

[@tam1381]

Ivan big pressure and you passed.... Your the man.

[@RickyLaneMusic]

Who'd have thought such entertainment would come from a repair shop on Staten Island! Great job, Ivan.

[@DaveSender66]

Pulsar is an awesome tool. Keith put you on the spot because he knew you could handle it. Ivan you and Steve work real well together! 11:00 at night and you are responding Like A Champion to anything he throws at you! Ivan you are an incredible diagnostician!!!! Thank you Keith for all that you do!!!!! Looking forward to more case studies.

[@PineHollowAutoDiagnostics]

Thank you for the positivity, Dave! It was an epic trip, always so much to learn. And Keith is the best mentor anyone could ask for :) And Steve is always a riot haha

[@keltecshooter]

I'll never forget my instructor at GM training telling us you have think like the computer when diagnosing issues such as these , nice job with your channel

[@kellyherald1390]

Congratulations!!! You passed your yearly Keith Certification.

[@Paul1958R]

Ivan, Keith, Steve, Great to see you guys working together. Great video and case study - thank you! God bless Paul (in MA)

[@joeandgod1]

I actually think you're better at diagnostics in general than some other people, I won't mention names, but their name starts with a K. Your humility allows you to explain everything in an easy-to-follow and precise way. You talk out your thoughts and teach at the same time.

[@ScienceOfDiagnostics]

Awesome job Ivan, you nailed it. This is almost as good as being there. You three definitely make some of these jobs look darn easy. Keep up the awesome work. 👍🏻👍🏻

[@PineHollowAutoDiagnostics]

Thank you for the comment! Keith was kind on this one and didn't make it too hard. Some of the cars that he sends me on are much more involved...

[@ablackformula]

After watching some of Keith's other videos with the Pulsar, I started an email convo with IPAtools.com (who USED to manufacture the pulsar tool.) They informed me they are "considering" a new improved model of the pulsar 9000, which will either be late this year or early 2020. I'll bet if enough people inquired and influenced them to make the tool, it'd help! Keith if you see this -- let them know we want the new tool! You seem to be in contact with all major companies and their support teams :)

[@NewLevelAuto]

I spent a half hour this afternoon on the phone with their VP. 😉 Awesome company

[@ablackformula]

Saw this tool in one of New levels videos a few months back. Tried to buy one from several sources. Can't find one anywhere. What a drag.

[@VoltageDropDiagnostics]

You 3 running around Staten Island looked like you were all having a blast!

[@satamanschmidt3428]

[@nikolairomanov3160]

For the final step I would Ohm'd or Toned those 3 wires with ECM end but it was way too late and Keith told the problem so ok hands down. Loved it.

[@jeffjankiewicz5100]

Keith and Steve kinda set you up for a timed test. Great job Ivan, nailed it!!! And in good time too! Like Steve said....you`re awesome! Logic rules in diagnostics.The pulsar is a cool tool.

[@mikechiodetti4482]

Bad PCM. Nice Diag. You passed Keith and Steve"s test!

[@DIETRYING001]

GREAT diagnosis! well done Ivan not easy to keep your thought process under pressure! although it was only for fun!

[@5Dale65]

The last thing I would check is if the connector is knackerd somehow, shorting across the pins to ground.

[@Craig1967]

Good job! My guess is that the original coil failed (internal short) and blew the FET and/or damper diode in the PCM. It is sad how many of these things fail that can easily be fixed on a electronics bench. But customers want it fixed NOW! If it was mine, I certainly would take it apart and fix it myself.

[@armandolios4561]

Man, 3 experts having fun...can you ask for more?.

[@partsshooter]

1st thing i thought was a coil circuit, after you mentioned ASD relay fuse.... I had a customer I lost as a customer because i couldn't repair their car [didn't have the technology or resource], Hyundai sonata with a blown ignition fuse! He called and told me what the dealer found [which was nice] And I never forgot... This was 6yrs ago😁 live and learn

[@PineHollowAutoDiagnostics]

Yup as long as you learn every day, there are no limits!

[@wyattoneable]

That's a cool tool, you guys are up late and wow. Record time in diagnosis. That was interesting as well. Thanks for the step by step procedure with your commentary. It all made sense. :)

[@real_arbuckle]

Awesome! Aw inspiring to see so many of your talents come together as one in this video and of course the diagnosis was on point as always. Thanks for sharing again!

[@mjmcomputers]

Nice job, I was going to say next step ohm test the coil. Good call on checking the control side.

[@dylankinch2735]

Man this one one of the coolest videos ive seen in a while. U guys should do more like this when u have an extra few mins. Very entertaining and also great job ivan. U nailed it bud

[@PineHollowAutoDiagnostics]

Glad you liked it Dylan! Didn't really plan it that way, Keith and Steve just decided to put me on the spot haha. Maybe this can be a new format...diagnostics with a stop watch ;)

[@brianmason1414]

That's AWESOME! Due to my own lack of experience, I would have replaced the coil since their wasn't any spark from it, thinking it was the internal short....(I admit, I have been humbled, again...lol..)

[@jdtractorman7445]

That Pulsar tool is neat. I have a short circuit tester that you put in a circuit breaker in the place of the blown fuse. Then you use this needle gauge against the suspect wire to see which way the needle bounces (left or right). That tells you which direction the short is in the wire. Of course it only works if you can access the wire easily which isn't always the case. It works though, a very handy tool. Good video, I've thought about getting a tool like the Pulsar or maybe the "power probe", anything that will assist with electrical diagnosis.

[@frugalprepper]

Very Nice. That Pulsar is a nice tool. For now I just have my clamp meter and homemade fused wire loop and a bucket of fuses. I've been trying to talk myself into one of those circuit breaker fuses but I haven't done it yet. I don't get to do as much troubleshooting as I'd like and video like this are super helpful learning experiences.

[@jamesd2482]

Was thinking the same thing about a circuit breaker since I'm not a mech any fancy tools outside of a scope and amp clamp wouldn't be worth my needs. Not sure even that would be necessary since it was blowing the fuse we knew current was high and a short to ground was suspect. I wonder if the coil had anything to do with it frying though and would be hesitant to slap a new computer in without checking everything on that circuit. As a dyi person my main goal is to save money and not use spendy tools if I can.

[@goodautodiagnosticsllc7475]

Another great video Ivan! No real pressure. You worked right thru it and found the culprit. I gotta find that Pulsar. 👍🏼👍🏼

[@smetal2008]

Well done Ivan!!!!

[@windward2818]

A smart ignition IGBT pre-driver IC (or monitor circuit) for ignition will have full diagnostics on the driver itself. So, if the driver is not being commanded on by the pre-driver, but the output is on (being pulled low) then the PCM should be able to report status (PID) or fault (DTC) on this circuit. This is helpful if you want repair the module yourself (replace a shorted IGBT) or if you want to send the module out for repair. Also, we are assuming that there is not issue with the connector pins, either corrosion or a bent pin on the module side. If you look at the battery for this vehicle, if not original, many times it will look small compared to the room available on the battery tray. This is because the original battery was actually a special sub-category of the group size (special meaning high output) which is no longer available. The closest battery to the original available is actually one made for a BMW. I know for a fact that the battery replacement listing for AAA in their look-up roadside cross reference is the wrong battery. With the vehicle stand time less than two weeks and expected life or about 4 months.

[@iduimovic]

Ivan, you make the difference between a "mechanic" / parts changer and a real technician that does a proper trouble shooting diagnostic. Any other shop will say you need coil pack, spark plug, wires and a PCM.

[@PineHollowAutoDiagnostics]

Well they already replaced the coil pack and plug wires...then they called Keith haha

[@SmittySmithsonite]

11:15 - that image of Keith should be in a professionally produced intro to any Staten Island Express videos! That is friggin priceless right there! Have Ivan say, "Why is the ignition coil drawing 14 amps?" then, cut to Keith at 11:15. Video GOLD! 😎👍👍 I did a timing belt on a PT Cruiser once ... outside, in February, right in my driveway. I still suffer from PTSD from that. Did I mention I HATE PT Cruisers? 😁 I've never cursed Chrysler so much on one job in my life. I was ready to set fire to that toilet! The best day of my life was a year later, when I hauled that turd to the scrap yard where it belonged from day 1, after the engine went Chernobyl - overflow tank was FULL, so the owner said to me, "It's full to the top!" He tried to drive it here 20 miles. He made it 18, at least - towed it the final 2. The head gasket turned to vapor.🤣 That was the best thing that could have happened - he got another vehicle, and hasn't broke down yet!!😁

[@PineHollowAutoDiagnostics]

hahaha great PT Cruiser story xD

[@SmittySmithsonite]

@@PineHollowAutoDiagnostics - Any story that ends with a PT Cruiser going to the crusher is fantastic. 😁

[@graymodeler]

I followed what you did. I think the grounding in the pcm can pass 6 amps but not all circuits can do this? In the old days the device was always grounded to the frame and the on switch was before the load. Today, since there is voltage drop through the load, the Pcm can more easily handle the reduced current.

[@Monkeh616]

They do low side switching because NMOS FETs are cheap and easy to drive. Current does not change by moving the switching point.

[@weldingjunkie]

That pulsar is really cool, lots of great feature. I’m guessing a vantage pro would work too changing a few fuses maybe.

[@JoelAutomotiveInaction]

I was wondering if when you unplug that connector at the PCM is that the same connector is powering up the coil side of the asd relay and now de energize no current flow unless I miss some thing in your testing, nice to see 3 great teachers .

[@PineHollowAutoDiagnostics]

Test light was connected straight to B+ so testing a direct short to ground :)

[@Charles_Mulberry_7977]

Ivan is the MOST awesome!

[@PineHollowAutoDiagnostics]

[@baxrok2.]

Amazing. Well done Ivan!

[@falcon8553]

Awesome diagnostic work

[@dans_Learning_Curve]

Double THUMBS UP! Probably a burned output transistor in the PCM.

[@dans_Learning_Curve]

Next question, what caused it to fail?

[@PineHollowAutoDiagnostics]

Most likely a shorted ignition coil!

[@cclngthr]

Test known good coil. Check wiring for short to ground

[@mikefoehr235]

Your videos are so interesting to watch. Ivan, you are no buddies fool to.say the least. Your knowledge and analytical method is amazing. Is a new PCM pricey??

[@JBTaylor86]

What was that, less than 30 minutes 👏🏻👏🏻👏🏻

[@BobDFish]

Would it be worth it to check and see how if coils are operating normally before calling it a fix? I remember an old case study on the South Main channel where a Caravan's misbehaving coil killed the PCM and probably wasn't far off from damaging the good PCM Eric O. put in it. These cases are probably mostly unrelated outside of correlating Chrysler product of this vintage + ignition-related problem + damaged PCM, but it does make you think. Well done under pressure.

[@rhkips]

So, it's been a while, and I'd love someone to jump in and correct me if I'm wrong... Weren't there two coilpack designs on the Chrysler 4s of that era, and weren't they wired differently? I feel like I've seen this before, replace the coil, wrong connector, get new connector, power and control are swapped, takes out PCM driver?

Good point, I did not know that tricky trick.

[@stevejones8665]

Just goes to show Ivan doesn't really need a fancy pulsar, just a good old fashioned Bulb and as Bodgit would say Sorted.

[@tracybeme1597]

Initial guess; plugged fuel tank fuel pump screen/filters. I'm thinking the fuel rail pressure sensor says that the pressure is low. PCM powers up the tank fuel pump but the fuel filter is plugged. The same sequence loops until the fuse blows.

[@tracybeme1597]

Simplest fix. Replace fuse, pull fuse, replace vehicle, re-insert new fuse. Whoalah Particimo. Repair complete.

[@bartscave]

Good job under pressure!

[@darwindwelle5267]

And Ivan is Awesome!!

[@tomvleeuwen]

There is one other possibility. It could be that there is another pin directly connected to this ignition driver output, for example for the rev counter. In that case a short on that wire would show up as an internal short in the ECU.

[@PineHollowAutoDiagnostics]

Interesting thought. On these newer vehicles (no distributor), the rpms are usually derived directly from the crank sensor, so the ignition driver circuit is independent of everything else :)

Been using the same tool.. just recently had vehicle blowing fuse when applying brakes and turn signals..
