This just helped me get a customer out of heavy traffic. Same issue, 2007 Prius cut out on a main road, blown AM2 fuse. Put a new fuse in and blew straight away. Unplugged the inverter pump and drove it to a side street so a tow truck could take it for repairs.
I'm new to your channel, ao I don't know if you use that format often but I really liked it. It felt more like we were there while it is happening and we are witnessing the thought process as it unravels rather than having an already done diag. explained.
THIS IS WHAT WE REALLY NEED TO SEE,,, I UNDERSTAND EVERY TEST YOU MADE AND EVERY STEP YOU TOOK SERIOUSLY I COULD HAVE THIS SEEM PROBLEM ON A DIFFERENT VEHICLE A FEW MONTHS DOWN THE ROAD AND I STILL WILL BE ABLE TO FOLLOW THIS DIAGNOSTIC PROCEDURE . THAT'S BECAUSE YOU STAYED ON A FOCUSED TRACK AND MADE IT CLEAR WHY YOU WERE MAKING THE TESTS . FOR A DIAGNOSTIC PROCESS THIS GOOD THIS SHOULD HAVE BEEN IN 1080HD OTHERS THEN THAT YOU'VE GOT YOUR SELF A RUclips WINNER 👍👍👍👍👍👍👍👍👏👏👏👏👏👏👏👏👏👏👏
Good stuff. Going through in great detail is much appreciated and what is missing on most wrenching videos. Keep this type of content going and I see this channel getting huge. Quality video!
Thanks for the circuit breakdown and mostly thanks for EDITing out some of the time looking around that we don't need to see, just show us the important items and locations, much appreciated.
Great job Thank you! I prefer to use a light bulb to find a short but this is another excellent option especially when it's not constant and you have to drive to get it to happen.
I knew from beginning it will be inverter water pump coz using this car from long time and almost know every little bit of this great car but not surely for diy users.great and detailed explanation sir.cheers
Can I come n visit on my way to c son in Florida, so glad I found ur channel, u folks r amazing, so glad u call naturally aspirated A engine, thanku, I tell other channels what r u gonna call a tesla a engine or a drive motor. Sry for rant
Nice work mate. One trick if you only have a 2 channel scope like I do would be to isolate the other things by unplugging them, had you unplugged the coils and injectors and had the pump running with the scantool this video would have only been 15mins long..
Great stuff. I use 21watt bulb across fuse terminals and amp clamp but only have 2 channel scope but always get there in the end . Bright light short dim all good depending on load .
Was it the AM2 fuse? I had the same. Inverter coolant pump went bad blowing the fuse. Disconnect the pump and replace the fuse. Should be able to get a short distance with it. Replacing the pump is a relatively easy process for a DIYer.
depending on the complaint if i feel its possible for a blown fuse to create the problem i check all fuses in all boxes first some of the youtubers say shouldn't be done that way. and yes i understand if its a blown fuse i need to figure out why the fuse blew. like a blower motor if it doesn't work on any speed i check fuses first if it runs on high i know motor is good. lets say i install fuse blower runs then check to see how much motor is drawing to see if thats the reason fuse blew. i see so many test and test to find blown fuse i just start there on most cases.
A little curiosity is getting the better of me and I wonder if any Toyota techs could explain how the inverter water pump works and what it does. I used to always assume the pump was there to give you heat and HVAC functions while the engine is not running. However, the fact that this pump and the engine obviously were running at the same time leads me to believe this assumption may be false. Anyone know more than I do?
The power inverter, which is in the large, silver-grey box in the engine compartment in front of the driver, in a Prius creates quite a bit of heat, so, any time the car is turned on the inverter's cooling system runs to keep it from overheating. That pump, which sits below the left headlight, is what circulates the inverter coolant. It is separate from the car's HVAC system (although the engine coolant and inverter coolant do share the radiator). If you remove the cap from the inverter coolant reservoir (next to the inverter box) while the car is turned on, you can see the coolant "stirring". It's a great way to see if the inverter coolant pump is actually working. If the coolant pump fails the Malfunction Indicator Light (MIL), which appears as a large, red triangle on the dash, will normally illuminate.
@@rc4211 That is a very good and informative answer. I did not know there were two separate cooling systems, one for the HVAC and one for the inverter. Is there also cooling for the HV batteries in this vehicle? I have seen some models use coolant to cool HV batteries, and I have seen air blowers used to cool them.
@@kdmq In the second generation Prius, which is the model shown in this video, the traction (HV) battery is air cooled. The blower is located inside the car above the right rear wheel well, behind the liner panels. The blower is connected to the traction battery using black plastic ducting to the right hand side of the metal battery casing.
As we said below. We really had no idea whatsoever. It’s up to you whether you’ll take our word for it. We haven’t said it again since. Keep in mind the person who edits all videos grew up doing service advising and now runs the shops, but isn’t a technician by any means. He doesn’t just sit around and watch videos like Diagnose Dan like techs would.
I’m glad you do these videos, gives people the chance to see what diagnosing their car takes, and your not just plugging in a computer to fix it.
Almost thought it was a Diagnose Dan video

NOT THAT I WILL EVER WORK ON AN ELECTRIC/GAS CAR THIS WAS IMPRESSIVE(GOOD JOB WOOD)

We do a little bit of both just depending on the day and the circumstances. We liked this one as well. Thanks!

Wow that's very helpful I'm not a mechanic by trade but I do work on cars and my own racer so things like this is something I never knew about
For the circuit breaker, I do the same thing always us a lower Amp breaker to be safe
Amazing diagnosis. Thanks for sharing valuable information. Much appreciated.
Another great job. Awesome work guys.
What and amazing diagnostic video guys thanks so
Much for sharing 👨🏫👨🏫👨🏫👨🏫👨🏫
Top video again. I'm learning a lot from you guys. Keep it up and thanks for sharing.👍👍
great job, I enjoyed watching your video ❤
Solid work Professor. I love my fuse saver kit. Excellent work using the tools and following the data.
Thanks for posting.
awesome video , great use of scope , good job
Outstanding lesson ! Thanks for letting us benefit from your expertise !
Thanks man. I like the way you teach man. It's easier to absorb the knowledge from you than the others I like. Can't ever learn enough.
Wonderful explanation and professional tools 🧰! 👍
you can't imagine how much you are helping diagnostic strategy for us
thank you so much professor
This channel needs more subs! Excellent job!
Multiple sources of information to triangulate on a fault. Love this video it’s excellent.
Tanulságos,jó videó csak így tovább!

Is that Bradley Cooper's dad? Great videos, very educational.
Another great one

What 2 channel scope do you have ? I always recommend the 4 channel micsig SATO1104 scope
@@thesmartguy3523 I have a picoscope
@@thesmartguy3523micsig, Is a gun.very good scope.
Amazing channel! Love it!
Cant you use a power probe hook and set circuit breaker rather than that kit with all that crap?😜
New subscriber.
Great teaching!
What does Toyota mean by "Synergy drive"?
Nice

Disconnect the pump and replace the fuse. Should be able to get a short distance with it.

Coolant pump shorted. Very common
Can we see a full walkthrough of an evap leak diagnostic? Some of us still struggling out here LOL
We got you!
i forgot to say typically it would be the cluster causing the no start / no run oddly enough
Darn it I know the answer!

Is the battery still in it
Gotta close that door man that beeping hahaha
how many miles??
Would an inferred camera worked to see heat as amp rises?
Yes it would.
Yes absolutely!
Someone tried to steel it 🤣
You need an original slogan, Lets diagnose this together is taken by DiagnoseDan
Lol wasn’t aware of that. It’s not our slogan. Just put it on this video. Sorry Dan!
i agree 😂.
What's with the wild hair,shocked from England
Listen I love this channel but can y’all edited these videos more? Holy yapperton…
WOW, stealing Dan's catch phrase,
The shame of it all

Why it's blowing something happening this is where I need More experience because so many things connected these cars
