      I've got 2ea 2001 Honda gen-1 Insights (1's a parts car) and it's been an interesting learning and parts getting process. It's a bit different design than the Toyota. Getting into the HV components in the back (battery and HV controller) my hat's off to the Japanese engineering team. The designs and functionality relationships, even at 21 years old (closer to aerospace than automotive) are exquisite!

      There's an interesting political history behind the gen-1 insights. Honda took a loss on each one sold here so-as-to bring their vehicle fleet gas-millage average up thereby qualifying for their highly profitable sales in the USA, and to continue with that revenue stream.
      Tesla, (a great product) the largest volume EV producer is about to loose their dealer-exclusive maintenance position as all their competitors don't use that strategy. Whoever can hire the tech's and fill that nitch stands to do well, assuming the psychopaths behind the world's proxy puppets don't have their tslking-heads blow-up the world first.

No matter how long you have been in the industry you will always find something new to learn.

    Hi Paul, once again, amazing video. The frame wire the interlock wiring diagram is referring to is the large Orange DC cable that goes into the top of the inverter. The connection at the inverter, the service plug and inverter cover have an interlock connector that open circuits when cable is disconnected or cover is removed, bringing up the P0A0 code. The interlock circuit is a high voltage check circuit, the circuit loops through the three points referred to above and if any of those points are disconnected the ECM will see an open circuit, if the vehicle is operating it may shut the system off or prevent restarting once switched off. 12v is put out by the power management ECM and so long as the circuit is complete 12v will return to the ECM. In a complete circuit 12v going out and is compared to 12v returning which produces a circuit potential difference of 0v. If the interlock circuit is opened; in your case the service plug interlock connection was open by it being pulled back and unlocked, 12v was sent out, but 0v returns to the ECM, therefore the potential difference between each side of the circuit is 12v, hence the fault description as "circuit high".

    Hey Paul, I love your videos. I’m a tech in Sudbury Ontario, a general consensus in the industry from what I have learned from other techs, is that the code “replace battery pack” is a code solely related to the battery pack. It’s noticed a cell that has had an internal failure and before the high voltage battery causes a dead short (like in a regular gas engine that would burn up an alternator) it would potentially cause a fire hazard.
    So I would strongly recommend a replacement battery for that vehicle. As it’s a pretty important code and we all know how batteries not in good health can cause issues.
    Love your content. Learn lots!

  • @shauno3697
    @shauno3697 2 ปีที่แล้ว +2

    One of the last shops I worked at had a couple techs that were trained in the hybrids and I recall one of them telling me that the water pumps always cause cooling problems that lead to faulty head gaskets. One of them even bought a Prius because their customer didn't want to spend the money on it. I'll edit this post if/when I can get a little more detail on the cause/effect.
    That aside, I"m glad you showed us your inexperience and a willingness to learn directly on the car. I quit the last guy I worked for after just one week because.he showed a certain inflexibility to his own inexperience. I honestly think he's going to be the first guy to try and compression test a Tesla.
    *Edit* I'm told that failing water pumps don't help, but head gasket failures aren't entirely tethered to water pump failures on these engines. That's all the more specific I got out of him.

    Under the inverter plate (the 10mm bolted on) you’ll find a high amp glass fuse. The system has 2 water cooling pumps, one for the gas engine and one for the hybrid components. 2 different cooling systems. Always disconnect the orange connector at the hybrid battery before working on the hybrid system. My first mechanic job were with these Toyotas in a taxi fleet here in NYC.

      probably failed inverter/motor pump, which shorted and blew a fuse in the small under hood panel, which disables the whole car instantly(driving down middle of the road in traffic ☠️).
      I forget the fuse number and if it's 10amp or 15amp, but it feeds that pump and part of the ecm or bcm and other circuitry.
      it will not power up the inverter/motor to start the ICE or do anything else but throw the big triangle of death and other I'm broken lights.

    My name's Morgan and I used to be a parts changer.
    Okay so I bought a 2002 q45 about 5 years ago and right away had an intermittent stall, I am still super new and learning about these issues but manage to find scannerdanners 2002 q45 video and it leads me to fixing it. FAST FORWARD TO ABOUT A YEAR AGO, I am fully hotrodding this thing but still very much an amateur. I am facing the most random intermittent issue where it feels like the throttle sticks after it's first hard acceleration, key cycling fixes it for about 5 minutes. At the time I have an oil leak into the alternator and I learn about false crank signal from failing diodes so I replace the alternator and it fixed it, car seems fine over the winter but it comes back after long drives in spring, gets back to the point of being about 10 minutes into the drive or one pull. I get NDS and confirm that something is pulling timing all the way to 0° advance, no codes. Being a parts changer and a smart ass I replace the alternator again with the original one remanufactured, instantly throws throttle body code and stalls. I replace that alternator with an OEM one, codes are gone but timing issue is back.
    At this point I'm almost 1500 into parts (solenoids, sensors, throttle body, 2 alternators and other crap I attempted), I watch scannerdanners Q45 video and it's like he's talking directly to me, DONT BE A PARTS CHANGER. I do my research and as I'm going through the grounds I find a split insulation on the cam sensor block ground and the copper is corroded, I clean it up and patch the wires with liquid tape and harness tape (I plan on replacing them, just waiting on double eyelets). 25 minutes into the drive and full timing, zero hiccups and other things feel smoother as well (shifts at low speed feel way better).
    It all comes full circle back to scannerdanner.

First, the main plug must be disconnected to avoid any complications during work. If you want to remove the battery, you must use it to remove the rest of the small plugs on the battery cover in relation to the code for B on the water pump, this means that the problem is in the same pump, and you can check through the engine information and compare the rotation speed of the pump with the expected speed, so that the difference does not exceed 150 revolutions, and if it is an increase, I advise changing the pump if you get a code, not “E” means that the problem is in the electrical circuit of the pump

You pull that and shuts off the voltage, btw these engines are famous for head gasket issues! Replaced one of those engines a month ago and thank God everything came out great.

    Those motors, like in that pump, are becoming more common and have been common in computer fans for years. Look up “4-Wire Pulse Width Modulation (PWM) Controlled Fan” for lots of write ups on how they work. The ECM simply looks to see the feedback is within some range of the command.

    I remember that service switch from the ChrixFix video on replacing the hybrid battery. You pull sideways then pull that lever toward you and the service plug comes out of the battery. That’s the part you put in your pocket.

    There is a red flip cover in the fuse box where you can get 12v or give 12v if you leave the dome light on for a week at the airport. I like you channel. I have a P 261B in the driveway right now. Your diagnosis is much quicker than what Toyota Manual suggests. What i have is intermittent so i am slow to just change the pump without further checking. It seems they will shut down with little warning at highway speed on a pump error code. Thanks

    FYI - On those head gaskets, I used Bars Leaks Head Seal. It is the blown head gasket repair with carbon fiber. It is around $40 a bottle. You have to just remove some coolant from the overflow tank and then dump it in. I have done 4 of them now. The oldest one was 2 years ago and they are all still running fine with no misfires. Pulling the head on one of those older ones is quite a job and will probably exceed the value of the vehicle.

    I hope you learn more about hybrid systems. I'm surprised you haven't worked on them before. I went through Hyundai's hybrid training when I was a dealer tech. It's an entirely different design compared to Toyota's, but I know Toyota's inside and out too.
    The Prius launched in 97 and came to the United States in 2000. Also, Toyota's system uses two electric motors, one big and one small, connected to the engine with a planetary gearset. The wheels and the big motor are always coupled. The high voltage system must be operational for the engine to start since the small motor is the starter/generator and can also partialy contribute to powering the wheels. It's a pretty robust system. AWD hybrid Toyota's have an electrically powered rear differential that isn't mechanically connected to the rest of the drivetrain. It's very low horsepower. Less than 50 HP if I'm remembering correctly, but that's enough to get you out the snow and mud.

    You’re absolutely right danner, you need 1000v gloves to even touch the safety plug.

    COOL! Followed you ALL the way through. Great explanation on it. Too bad the customer didn't want the repair made. Possibly just used you guys to trouble shoot, then have a 'friend' do the work changing it? One never knows. No matter how complicated they try to make the design, they can still only make it 'seem' difficult, but it's not so in the end if you understand how circuits work. Thanks, great video!

    @davidb.fishburn9338 2 ปีที่แล้ว

    Chrysler tech here... I have the training on the hybrid/full electric vehicles. I agree about not touching anything w/o the proper safety equipment. High voltage is not something to mess with when one knows nothing about these systems. But, that plug in the back, it is the main high voltage battery disconnect. What Danner found is the first interlock of that plug, it disconnects electrically, the rest of taking the plug out is mechanical. The orange color is only on the high voltage system. The other safety interlocks are automatic, they work when you disconnect the connectors. Btw, you don't have to put the plug in your pocket, just somewhere safe that you have absolute control over. As far as the gloves go, it's worth the investment to get them. I would recommend that you get the training, as as time goes on, you're going to see more and more of these vehicles.

It's posible that the pump is not running at the correct rpm , or as you said not running at all overheating the engine and throwing the pump code .

    The heavy orange cable apparently has a protective sheath with a ref signal running along it so if the cable is damaged it will prevent the system from turning on , Interlock circuit open or Interlock circuit short to ground (I believe) are the codes to be aware of.

  • @herrkiwi3110
    @herrkiwi3110 2 ปีที่แล้ว +3

    The interlock circuit code is common on that model if owner's start fiddling with components they shouldn't be or have stored tools or luggage under the rear tray and have "caught" the plug removing items. On the smaller Prius C (Aqua JDM) It is also common to find that the owner has usually tried to jump start the vehicle themselves and gone straight to the battery under the rear seat and have removed the wrong panel or lent on it to hard pushing the connector down resulting in the same code. Either way every time the instrument cluster will illuminate BUT the READY LIGHT will NEVER come on causing confusing. Most Prius models have a jump start point in the fuse box LHS Engine bay but this MUST NEVER BE USED TO JUMP START OTHER VEHICLES !!!!!

  • @ongong3147
    @ongong3147 2 ปีที่แล้ว +1

    When you remove the pump, you can check it by twisting it with your hand. You will notice some heaviness in it, which means that it is damaged, or when you disassemble it, you can notice some black marks on the heart, which means that it is damaged.

  • @youutartur1104

    Hey Danner, all gen Prius have a very loud flywheel dampener when it has a misfire. That gen Prius has a real bad tendency of blowing head gaskets, I would bet if you look down the cylinders with a boroscope you'll find a leak. Easy money for your brother, done many and that is the first symptom... I'm serious I don't know of many owners of that gen that haven't had a head gasket at least once in their lifetime. Also with the first issue and the engine starting, it uses the electric motor MG1 to start the engine and MG2 to drive the car in electric or assist mode. The engine also always runs about 10 seconds after "READY" is illuminated. Another way of forcing that engine on is Emissions Mode where you force the engine to stay on throughout an entire KO cycle. The loud hum that you hear from the water pump can sometimes be mistaken for the A/C compressor that hums really loudly and is normal.

    Diagnose Dan has a series of videos a year or so back where he goes through working on EV, complete with gloves and such.
    For electrical gloves, you need the rubber gloves, but also the leather protector gloves. I've found Magid Glove who sell PPE equipment have decent prices and good info.
    The "put it in your pocket" seems like a weak lock out, tag out system. Shop probably needs to get a keyed box to put the cut out in while working on the car with the tech doing the work keeping the key.
