We have a 2007 Toyota 4Runner with multiple failures! Multiple EXPENSIVE failures! Follow along this case study and see what it takes to fix this one!

Great case study, PJ! Some people may have tried to unstick the transfer case with the Tonya Harding 3000 but I’m sure they would have failed. A bizarre case but it was a perfect challenge for your skills!

Thank you PJ. Good job. Have a great weekend.

The amount of amazing wrapped up in this video is absolutely under-appreciated...Pat, you are always always always doing something that has a HIGH DEGREE of value my friend ❤️ Thanks for continuing to work hard to be the best at what you do brother!

Gotta love the multi layerd problems. Fix this, find that, fix this, find something else, rinse and repeat 😤

Great case study! I had a 4wd Sequoia with a broken limit switch wire causing the 4wd sequence not to complete and the 4wd light would flash but not fully engage. Major headaches sometimes having to test at 4wd ecu and vehicle on lift etc...
Great job with the videos look forward to seeing more.

now this is one of those where you must know and understand how the systems act together. unfortunately there is no standards so each manufacturer has thier own way of doing the same thing. being brand specific has advantages over the repair shop on the corner

Good job but please stop pounding the desk becuse I can hear it on my end. I enjoy watching your videos great job.

Thats an awesome case study. Man im sure it was super frustrating. The 4 Runner that didnt want to leave lol.

The 4low wouldve tricked me up. Great content as always. Thank you

Very good, your really easy to follow, i like that.

Being a technician and listening to somebody else explain the situation brings me back to the realization how much I missed points and one ignition wire through one resistor and one coil that could be repaired with a single screwdriver and the paper from your matchbook cover 19 thousandths to set the point gap to get your car running again 😂

but I do not miss those days of having to readjust my points every 12 to 15, 000 miles and reset my dwell and timing. And having to change spark plugs every 30, 000 miles.

Thanks for the case study. Enjoyed it.

Craziness, thanks for explaining that internal pull up resistor. Or pull down, I guess depending on if you're looking at it from an ecm logic. Not always knowing those facts about the internal circuitry can really send someone down a deep rabbit hole. I think you did the correct thing though, without finding those bad connectors a new ecm could have been fried and back to square one. Great insight, thanks much

Excellent, great diagnostic and explanation, im working on a crazy Toyota land cruiser prado 2014 now, the car had the battery going flat because of a light that the owner forgot on for few days, when they came to change the battery the car wouldn't open with the transmitter, they opened it with the key and the alarm system kicked in, they changed the battery any way and they tried to start ghe car but nothing is working and the theft alarm system keeps kicking in, came to the car to do the diagnostic, key is blinking when you push the transmitter button but nothing is moving in the car, nothing happened no matter what you do tried to push the start button with the key, tried even to make another key by backing up the immo data with lonsdor and the emulator, back up working fine but the touch to start button is not letting me turn the ignition on, and managed to wake the car up with the ignition circuit to do a full diagnostic, all the ecu's are on the line and working perfectly, no dtc's at all, i will be back tomorrow to check if the certification ecu is giving the command for the oscillators and touch sensor around the car to work (the car is equiped with entry and start system), iam thinking now that maybe the certification ecu is down !, Everything else seem to be working fine, it's all because the car seem to not know that the key is inside it ! Any idea ? And sorry for the long comment

Sick case study 👍That's 3 very difficult problems to diag combine in one, really making it nightmare.. Still i wonder, if changing the transfer case unit with the actuator would fix the car finally?

Well edited 👍. Everything made sense.

I absolutely love your videos and derive a great deal of enjoyment from them. I realise this is off topic but I could do with a bit of help. I'm in my late 70"s so it's not worth my while investing in fancy tools. A while back you diagnosed a misfire on a Prius. My Prius '05 has a misfire, is there a way to find which cylinder it is without your sort of tools? I would usually check temperature of the 4 branch, but thats nigh on impossible with the Prius.

Thank you for a great vidio .
Can you please share with me how to make the ligth connections for a tester for my self I’m sorry I just learning through watching your vidios and I love it .
I appreciate you
