Sometimes it just makes sense to locate and mount electronic modules in an area that isn't the hottest place on a vehicle. Way to go Ivan. We need you on the west cost !
NO NO NO NO WEST COAST, SIR IVAN IN PA. I agree though mounting shit like that in the HOTTEST PLACES IS STUPID. I have a 4.0 in my Jeep & the intake is right above the exhaust header ? Fuel rail also gets pretty hot but I've put a lot of insulation on both ( PAIN IN THE ASS ) but it helps loads.
Some people put heatsink compound of the ICM to try to transfer some of the heat to the car's body. It looks like there is an exposed metal plate on the back of the module.
I am LOVING there being 2 videos featuring 1 of my 3 favorite automotive detectives AND the old Isuzu 3.2 that I've owned and worked on for 26 years! This is like crack for me (o:
Ivan is the Passport to smooth running. The fan clutch replacement should make it more quiet and help with the gas mileage. Nice job Ivan. Most people who don't have the diagnostic tools would have tried replacing the coil and been disappointed when that didn't work. Heat is the enemy of electronics in the long run. Great tutorial.
I gotta say that I rarely work on my vehicles due to time constraints. However, I'll spend hours watching you repair vehicles that I don't even own. LOL. I really enjoy watching the analysis, logical problem solving, and out come of your videos. Thanks for doing what you do and for sharing with the rest of us.
Same. What I've learned is (j/k) to just go ahead and replace the MAF, crank position sensor, cam sensor, TPS, PVC valve, EGR, sparkplugs, coils and wires, fuel insjectors, all O2 sensors, all fuel pumps, plus all fluids and all filters, and most of the problems Ivan works on would be solved. And those that aren't mostly involve "green crusties" at a connector or damaged wires.
Certainly earned the pay check on this model. Very thorough diagnosis and with the schematics, easy to follow along. Relief to see her act up a 2nd time and read the codes. Lucky to find a replacement unit on Ebay for your customer who must have been delighted with the successful outcome. Was back to it's best behaviour judging from the road clips. Handy having a steep climb nearby to put them under pressure. Job well done.
With the mileage that’s on the vehicle I would have sworn it would come down to improper valve lash adjustment. I’ve had many of these once properly readjusted, they ran perfect. Good job as always. Good follow through.
Nice job Ivan! Sometimes a hill makes the difference. I had a good one near where I used to work. It went around Dodger Stadium, a park and a police training center. Amazing what a load does to bring out a problem!
As always Ivan great job, parts unavailability was why I got rid of my 01 trooper, it ran great, not great fuel economy but reliable transportation for a long time and lot of miles
Very clever DUT configuration, brilliant Ivan, excellent diagnosis as per usual. Thanks for sharing and best regards from the UK, home of the PicoScope 🤗
Ivan, "Is it a bird, it's a plane, no, it's Superman! " That's you Ivan. Ivan, once again, science and logic overcomes superstition and medieval fear. :) Loved this case study. My head spun when you were figuring out the cable connections for the O2 sensors. :) Hey, wasn't that a "Heat Sink" on the top of the GM replacement module? The one you removed didn't have one. Thanks.
Sherlock Holmes of automotive mechanics! Great sleuthing, Ivan! I'm betting that this vehicle will return again in the future for you to find a few more surprises such as wrong parts and parts in the wrong places. LOL
Another great video from you. I've been watching your video for about eight months and I do appreciate it. Just to let you know a little bit about me I'm 70 years old and I stopped working on my vehicle, all I do is change the oil and do a couple of the things but the electronics is kicked my ass and I'm too big to put my hands around all that stuff
At 65 I'm with you. It is good to learn from these youngsters so we know if we're getting fed a line of BS if we go to a shop for work. Plus we can ask informed questions.
@@billburkart9087 Bill you're absolutely right. But I have a mechanic for 30 years doing work for my daughter's car my granddaughters car and sometimes my wife's and my pickup things I can't do. You remember the old days when you just had one craftsman toolbox with all the tools in it and everything was pretty simple
Well I’m sure gm realised that you don’t put modules on top for rocker box,ie vibrations,heat???but you Ivan ,very good diagnosis,enjoyed the logical diagnosis.good video.
What I really appreciated about this video was the value of the scope. I was going to say swap the coil. The missfire would have stayed with number four. That is the bad driver. And I really thought the coil was bad. Current ramping the coil was the key. I just try to think what would I have done. Great as usual!!
now, I wonder what helped kill the original module and that replacement module? lack of tuneup and resulting bad coil/s? I'd have looked at the coils/boots more closely just to be sure it doesn't bite back. also I believe he said in previous video valve cover gasket/tube seal change, so I assume the tube plug was full of acrid acidic oil and arcing away (think what that does to coil current and what that would "harm" upstream) I'd say someone was repairing the symptoms and not the root cause in the past... ;)
Well done ivan :-D, i wonder how the hell it worked at all with the sensors confusing matters. I bet that after market driver module can have the potting compound dug out and new mosfets plopped in.
On my old Hondas (w/dizzy) and no spark condition, I would remove the cap and disconnect the wire at the igniter terminal that connects to the coil negative. Then connect a test light between battery (+) and igniter terminal. Crank the engine -- if the light flashes, igniter good, coil bad and vice versa. ICM is just a ground breaking switch.
You would think that gm part would fit other vehicles. The waste spark start up makes sense because it helps engine start faster. Also you should of got the customer to let u tear the old module apart and see if you could fix, Since its impossible to find.. would of been a cool video.
your passion and thirst for knowledge and also to confirm them to your memory with known goods is the extra mile you do for the next problem solving issues. You love intermittent issues, love to get your mind challenged, is wonderful to see, I know if your stuck you dont sleep well and read read read people around you are lucky to have you after the huge investement and not one time investment in tools and wiring and knowing where to look and how to read scopes, wiring diagrams, and seat of the pants instinct are great, you are a lifetime learner
Driving down the freeway and I hear you say-- good power. When it was running right up on the mountain pass you gave it the beans and I watched the tack. No this car will never ever have "power". If my 2000cc Toyota was climbing the pass with a load of hay it might act like that giving it the beans.
My old iron duke 4 banger in my boat would run great to my fishing hole about 8 miles from the launch then once shut down for a few mins it would not start back up. I would have to sit there for a good hr with the cover off the motor to help cool the coil. My coil was bad. Put a new coil in and bam, fixed for good!
I used to work repairing televisions, and an older technician who worked on tube sets understood the importance of examining electrical waveforms (in those days, a cathode ray oscilloscope) like you do, called many people who just 'swapped out' tubes as 'tube jockeys'. Many times they were 'caught' with a misdiagnosis. For what initially was thought to require a 'coil pack swap out' proved more to be a time-waster in finding a solution (all those miles travelling without a misfire), but many times ICM's only present a 'fault condition' after several miles of travel in varied conditions, where OBD (on-board-diagnostics) is crucial in detecting a misfire, and the use of 3 traces on the 'pico scope' finally presented a fault diagnosis, but again only when the ICM, on just one cylinder, decides to fail... Your persistence is admired...!

Any Brits notice a striking similarity between this vehicle and the Vauxhall Frontera? These vehicles are almost totally gone from the roads these days. Great fix Ivan.
If you fix that fan clutch, it makes a big difference on power.. I have one of these with over 300k miles, 5spd 4x4... It's one of my favorite cars I've had in my life. lol
I love heat-related ICM faults. I have a lawn-mower that stops producing spark when it gets hot halfway through the lawn. I get to lay in the hammock and drink cold beer and we cool off together. When we're sufficiently rested and cooled off, the mower fires right back up and runs like a champ. It's not a problem. :-)
We had a Passport on the used lot at the dealer I worked at back then. I borrowed it a couple times and loved it. If I needed a car, I would have bought it immediately.
i do like the touch screen pc... i have pico on one of my touch screen tablets but it dosent resond well at the edges when im trying to get the rulers down... good case study though....thanks for sharing.
I taught Automotive for 25 years, ASE Master Tech L-1 for 30 years . Taught Automotive Electronics for last years of my career, it is like welding if you dont do it everyday your lousy at it
Great job Ivan . How do you bill the extra check out time and the time finding the parts ? With the effort you put into it you deserve paid for every minute of it . If it was at a dealership they probably would have charged more total and not put the thought into the problem solving if they are paid flat rate .
Dude you have more responsible policies than most of the dealership services :) ...he should do some heat protection on those modules they are placed on a worse possible spot.
Mike Foeher, most likely it was to reduce assembly time on the production line, ref already fitted to the engine/transmission. But yes, heatsink or cooling would be beneficial, though don't think it handles much current.
no snow this year... you cant have a 'normal' winter mate with all those billions of acres of forest on fire around the globe.....somethings gotta give.....
I don't think it works like that, the northern California mountains have had a lot of snow aking with the usually colder areas of the northern US, where Ivan lives in Pennsylvania is far away from any fires, all along the east coast its been fairly mild, it's funny how people will complain when we have snow and complain when we don't, there truly is no pleasing some people.
@@Peter-pv8xx.....so you think all that additional heat and released CO2 is having no effect anywhere eh? Look up on Google how many billion acres are going up in smoke every year, this year's probably the worst ever with Australia's extra contribution......
This shows even the great ones that we tend to get complacent after a while, the young Ivan would have check to see if the coil was firing before swaping COP. it happens to the best of us. Good job still.

Why is there no heat sink for that module, considering it sits in the engine. Seems to be an odd place for something electronic.

My guess is the module won't last awhile.....the reason it was used in one vehicle for 1 year.
It looks like that module could use a heat sink on top of that bare GM metal surface...
It must startup in waste spark and probably batch fire because it hasn't synchronized the firing order yet. Or that's my guess.
