It’s been a while since I watched these Weber videos, but this presenter is a national treasure.
Thank you Professor - I now know many, many times more about IMA than I did a few hours ago. Thumbs-up rating given!
Thank you!
@@WeberAutocould you tell me how to charge hybrid battery on ima gen 3 ?can i contact you via email or whatsapp ?
You sir are an authority in these kind of teardowns, a pleasure to watch as always and thank you for taking the time in making these videos
Thank you
@@WeberAuto hello can ask one questions please According to you, should I choose an inverter with modul igbt or an inverter with mosfet igbt?
thanks!
Prof John Kelly thank you so much for the brilliant explanation. I've seen this structure in 2015, Only a slide. Now i understand how it really runs. Thank you a lot sir.
Pure Gold, this is YT at it's finest!
Awesome content, thank you Prof Kelly!
I'm not phased, your videos are electrifying.
just bought an '11 cr-z and here I am, learning a lot!
Felicidades profesor... gracias por brindarnos está explicación tan correcta. Saludos desde República. Dominicana
I had wondered how the power flow during regen worked. Thanks for the clear explanation!
Thank you!
When dismantling a complex assembly, I was told to always put the loose bolts halfway back into their correct empty holes where possible when each subassembly has been separated. It takes a little more time, but it means that not only are the bolts never lost but you always know where they are supposed to go when you reassemble.
Great idea, thanks
sir i salute you. with all honor you are the most charitable man on youtube
God brother! What an amazing UA-cam channel you have. I just purchased a 2003 Honda Civic Hybrid with 58,500 miles.
You are a lifesaver brother! God bless you. I was or I’m going to the car and most important your one of a kind video to the Honda dealer tomorrow :) God bless and thank you the world!
This informative video gave me things to look out for in the future if I ever buy any hybrid. Thank you.
Thank you!
Prof. I appreciate your in-depth thoroughly explained videos
Thank you very much
This is excellently explained. Can't appreciate enough.
Thank you professor. You are doing a great work .I am learning lost of by your videos. Keep it up professor. And thank you.
Thank you
This is a great example of HIGH quality content
Thank you some much!! I have a 2006 civic hybrid. You video help a lot. Your the best!! Also thanks for you very detailed videos.
Excellent video, Sir. Really enjoyed the whole footage :)
I used to own a 2003 Honda Civic hybrid. It was the most underpowered gutless car I’ve ever driven, but I found it to be an interesting challenge to negotiate traffic and freeway on ramps.
Eventually the IMA NiMh battery failed after about 7-8 years. Most of those years was when I lived in Dallas, so the battery suffered many brutally hot summers. Like he said, the battery draws cabin air to cool the cells then exhaust the air in the trunk. Because I would loose the engine auto stop feature, I never used air conditioning unless I had sensitive passengers. Running the AC would also cause a noticeable reduction of power when accelerating, and more importantly a drop in MPG! This certainly accelerated battery degradation since the cabin air temperatures was well over 120f in the summer. Plus when the car is parked out doors in the baking sun the battery is cooking for hours. For all its problems, I still achieved 44+ MPH for years of driving (and sweating) bliss.
44 mph? you must be a patient driver
I guess MPG
Considering battery is third the price of Toyotas - pretty good deal.
I love those videos thank you. Very informative as I'm planning to get a crz in the near future
Thanks for the civic hybrid info👍
Thank you so much for such a great information.
Thank you!
your review is amazing...I appreciate your work...keep it up
That was a very informative video , thank you professor.
Thank you
Am happy to be in your class sir and am really enjoying it
Wow Sir thank you very much. Exceptional explication!
Thank you!
Thanks for sharing your knowledge with us all
Thank you!
Thank you for sharing, Professor!
Sir, can you please confirm:
What instruct IMA motor to sense that on what RPM & TORQUE motor should rotate (Contribute to Engine's Load)?
Best videos in UA-cam. I wish I could take your classes
Thank you very much
Hello professor, I recently encountered an issue with a Honda Fit Hybrid where the hybrid system does not enable. all systems checked manually and with a diagnostic autel dealer level tool, the only error returned is the "sunlight sensor circuit" (code is B1229) would this stop the hybrid drivetrain from initializing?
What is a great scan tool for monitoring the batteries? I heard mention that you can monitor each individual battery with a scan tool but there was no mention about what scan tool to use.
thank you sir,love from Pakistan....
Thank you!
Incredible description.
Great information. My coworker has a 2001 honda insight with standard transmission. I was telling him that his vehicle had a liquid cooled Inverter. I stand corrected. I haven’t looked further into this type of hybrid but do you explain how the Standard Transmission works with the Three Phase Motor and the Engine?
Many thanks for sharing your knowledge professor
Sir what about the honda insight 2010 model some water seeped inside will any danger can occur or caution
I have an 08 Civic Hybrid. How do I tell what gen battery the Hybrid has?
Nice video , thank you.
How do I know if the Hyrbid battery is bad or if the inverter is bad?
Is there any chance there would be separate codes for this components? I have a code scanner.
Thank you professor !
Quick question i wanna buy a CRZ 2011 with the old ni-k batteries can i put tge new li-um updated battery from the 2013 models in ????
Hello! Thanks for this professor. Definitely very clear and concise! I have a couple questions on the parts according to my issues (open to anyone who can answer this as well please).
1. What symptoms can come about from a failed Inverter and failed Converter?
2. If a brand new 12V battery is installed and it does not die out but reading less than full charge (car on or off), can you rule out the HV battery being the issue and now focus on the converter/inverter failing?
Thanks!
interesting stuff, thank you ...
Thank you!
Can I change my Honda Civic Hybrid 2010 engine with a regular gas only Civic Engine? Can it be done?
Professor... IMA honda does not use the reactor and boost module as i can see?
Awesome series of videos!
Dear Professor, Can I use solar panels to subsidize or add additional charge to the Honda battery? If yes, where should I put the cable from solar panel?
You are the best, you are may profesor. Thanks
I wonder how we can update the software for battery condition monitor, on our own?
Excellent, thank you!
i am interested in buying a Honda fit / jazz 2012 model hybrid. I can't find a proper site with knowledge one the following questions you are my only hope or someone else here with true knowledge.
1)what gen is that model regarding its hybrid system and do you recommend buying it in general?
2)how much will truly cost a batary pack. not the process of replacing but the battery it self hoe much?
3)how can i check its battery cell condition before buying it?
4)how long do they last those packs if you take care of their Temps and charging?
Thanks for your time
I used this video as a guide to repair my 2012 Civic. Although not exactly the same it was close enough for me to remove the inverter and replace one of the IGBT units. The car ran fine, but 3 months later it appears that I might have the same problem again. I haven't inspected the inverter to verify. Both times it happened under braking, however you mention that it uses a rectifier in this situation. Would this damage the IGBTs? What would cause the inverter to go bad? I want to find the cure rather than treat the symptoms.
Please help! This is getting expensive and time consuming!
I like to learn to work in hybrid cars , any recommendations?
Would you please do a review of the latest Honda parallel hybrid system?
Wow it’s my first time watching you but it was worth it
sir....
please reply for my question i am in difficulty..
mine is Honda civic hybrid 1.3 IMA 2008 (2nd gen)
problem is
1.engine warning light came on rocker arm pressure switch(all is working fine like autostop,engine cruising at 40 speed but mileage"Mpg" was down side & after i take car 3000 rpm its limits and get jerking not going after 3000 rpm)
i took my car in honda for engine light.they told me your engine harness was bad..in two to three places cuts found..it need to change whole engine harness.(it is too much expensive in india because only 300 units sold in india discontinued)
but i dont understand why?? because honda mechanic showed me there are some problem in solenoid 4 switches.not too much wiring cuts only switches wires are cuts some i take it in my home
and i try at home 1st i disconnected 12v accessory battery then IMA switch also.after an hour with safety tool i removed engine plastic cover and i change all four the switches wirings so............... 1st problem was cleared and engine light is gon.after this problem solved my IMA battery get more backup and also glass power windows are fastly close and headlights are more brighten and 3000 rpm also solved and mileage is too much better..but when my engine light gon two more lights are on 1.is ABS yellow light also red &
2.transmission d also blinking
currently this is the problem autostop is not working mpg is good enough
ABS RED AND YELLOW LIGHT & TRANSMISSION D LIGHT BLINKING
i was checked all things i scanned a car code was U0129 (Lost Communication with Brake System Control Module)
i try to delete codes but its not deleted
please help me please answar me........
Thanks for the insight
That is good to know thanks for show us this if I wasn't knowing this but now I do
Where can I find the ima motor control module
Hi, do you know what could be wrong if you lose communication with ima? I was driving through and I wasn't aware that I was going right into a speed bump and I just passed it very fast, a few minutes later the ima and the battery light came up and the vehicule wasn't charging, I took the car to a local mechanic to connect it to a scanner and it appears that it lose connection to the ima system, we erase it and the car is fine again... is the second time it happens and I'm scare that if I get into a another speed bump o a street hole it comes up again and the 12 v battery is charging ok... has anyone has experienced this ?
I really like your explanation sir....😍😍🙏🙏🙏🙏
@Weber Is there a signal wire that controls only the "power assist"? I'd like to find and cut that wire so that the whole system charges like it should but without draining (144v) battery power for electric assistance. In other words, I want to convert IMA to a regular 2007 Honda Accord(v6) with a giant 12v battery supply, with NO Power Assist. Is this possible? Thanks for your videos!
Awesome video lesson
Super-Duper informative (Y)
Thank you!
Thank you sir....
Got a question sir i have a 06 honda civic hybrid with the ima and battery light solid on and i check battery pack and all cell are good pack is good so i order a good used working dc converter module and problem still there what could it be??
Thank you so much! I learned a lot about my 03 Honda hybrid by watching your videos. I do have some questions my card pmu is not putting power back into my battery. And I just would like to know a breakdown of that system and it’s components and how it works so I can fix the issue
Thank you!
Hola,donde pudiera comprar los módulos igbt para el inverter de un civic 2008?, gracias
thank you so much
2013 Insight FL driver here, still running original IMA battery AND brake pads YEAH . .
thank you it is great
I use my Hybird to power my house
When power goes. The car is the best
Generator in the world.
SUPER WORK SIR
Thank you!
Is it possible to replace a troublesome Mk1 144V LiMH battery with a Mk3 144V Li-Ion battery? Do the Li-Ion batteries have built-in voltage controllers (like a phone battery) or are they unprotected? Or, what would happen if you put 12 ordinary 12V lead-acid batteries in series (apart from taking up much more room)?
No, the charging strategy is different for Li-Ion. 12V batteries in series would be very heavy and not charge currently either
Hi,
Would you or anyone know where I could find a pinout and details of the control to the main ima inverter?
I'm wanting to drive one of these systems outside of the car.
Thanks in advance.
Can you do a review on the Dana Variglide torque converter?
It looks interesting, but I do not have access to one. It looks like a prototype.
Great Video. Thanks! Can you (or anyone) recommend a Gen1 Insight technical resource in Northern NJ?
Hi can I know inverter fan always on or when converter unit hot … fan going on?? Tnx
Hey Professor, I have an 05 civic hybrid, the hybrid high volt battery has died and I turned the bypass switch off and now he car runs on just gas and 12v system. Up till now no problems really, but lately the 12v battery is not being recharged, and I know that the inverter dc-dc converter is responsible for charging the 12v battery, im just curious, do I need the inverter only? Or the dc dc converter? Or the whole rig? Btw i have no plans of fixing the hybrid system, this car is used for work, and I’m just tryna keep it going at minimal cost possible. I appreciate any help!
u r great thank u so much
Thank you!
Is it possible to place a lithium ion battery setup in the 1st gen models or are they stuck with the nickel design?
You are stuck. Li-Ion batteries have a different charge rate, control algorithm, voltage level, heating and cooling needs, etc.
I heard the Civic Hybrid has reliability issues? Is that true?
I have a Honda insight a 2009 model hybrid and at night when I drive 🚗 it during the trip the IMA light appears on the dashboard it appears when I have drive between 5 to 6 kilometer distance what does it means it is dangerous then what are the damage it can cause on the engine
When I am driving and I lose the accelater the knocking produce but I again accelerate the became finished.
My car honda fit IMA engine model 2013
Is there any way to charge this battery when it is out of the vehicle, I no longer have the vehicle but want to keep the battery charged
Read p0562 any suggestions? I need help
Getting this on my Honda, and Honda recommends to replace the MPI....2012 Honda Civic Hybrid Codes P1440, P15A5, P0AE1
At 37:40 you mention a capacitor module - shouldn't you check for a voltage there before touching the contacts? Also, when you had the protective gloves on, it seemed that it might be easy to touch something with your uncovered forearm? How about having a store of thin rubber surgical gloves to wear for the delicate disassembly?
You are correct, I should have done that, but I have had it apart many times before and knew they were discharged. I forgot that important step
Congratulations for your channel, I really learn a lot here. I would like to share a recent situation, I bought a honda civic 1.3 hybrid and so far it's just a headache, I had to change the DC/DC converter because the bat 12v wasn't charging, now there's another problem and the honda mechanic has detected the problem as MCM (1B100-RMX-E05). I don't aproved because was so expensive. Then could you please give me a tip? I need to install an MCM in my vehicle, but my part is 1B100-RMX-E05 and I only found 1B100-RMX-E06, are they compatible?
Is it necessary to update? If I buy the reused part of the end-of-life car. It will work?
Thanks you are great
I have 2008 hybrid civic.having battery light on.its not getting charged.i have code in ima dc dc converter low voltage code.any help will be appreciated
Can you pass smog with out battary?
Sir..
Is there any possibility to emits some amount of AC ripples in to Auxiliary battery from This DC to DC converter.
Because i have case study that misfire counting and P0300 fault code. But no misfire to feel. Finally i found lot of high frequency noise on CAM, Crank sensors signals.
Then i test auxiliary battery that i found over 730mV and over AC ripples on it.
So i am stuck. where the battery get thta AC ripples. From DC to DC converter?
Any inputs would be great.
Thank you
Nice video as always. What brand printer and roll do you use to print those labels?
Thank you! It is a Brother P-Touch PT-7600. I use special "Strong Adhesive" label tape. You must clean all surfaces with brake spray cleaner before applying the label or it will fall off. Best wishes!
Thank you very much ❤
You're welcome 😊
What is the Ac voltage on the motor?
Sir 👌 good job 👍
Thank you so much for this video, new to Hybrid system.
I have 2013 Honda Civic Hybrid, I have a problem with my IMA, Honda Dealer service dept tell me that I need to replace
Motor Power Unit and 51HOZ : Body Electrical
trying to understand what they are, could you tell me what are they? If so, Do you think I could replace them myself.
Thank you so much for your help
08 Civic Hybrid, intermittent code for CEL (P15A5 Motor current sensor), took vehicle to dealer to have checked out, could not duplicate problem. Picked vehicle up and drove for 4-5 days not lights on running great. Light came back on same code, cleared code and drove 3-4 days no lights, now back on - tried checking all connections in IPU and under hood to motor sensor. what code be the problem where it intermittently does this. Need help with this, I know motor current sensor requires removal of transmission. Is the sensor the culprit?
