The old cynic in me say that if the guy who was fixing it wanted to buy it, there's not much wrong with it. My dad told me, never sell your car to the guy who's fixing it, if he doesn't fix it.
For those of us who like to diagnose fault codes like Rob and Chris have on the Infinity we need to understand that these sensors are just reporting that they haven't received or sent a handshake. It doesn't mean the sensor/unit has a fault. The remedy for multiple sensor faults is usually an associated localised ecu.
For anyone interested in learning how to methodically diagnose a sensor fault, I'd recommend a channel on here called Diagnose Dan. He runs a Dutch repair shop and receives vehicle that other repair shops cannot fix. Incredibly interesting and logical diagnostics.
I get Rob’s point of taking it to a specialist, but he’s coming across too panicky about not touching anything at all !
Chris still wanting to have a little play before it gets taken away and wanting to get his head around it
This is why Chris knows as much as he does about so much - massive respect Chris 👍🏼👍🏼
Chris definitely fancies moving out his lane and having a go at it regardless… Go’on Chris!
That’s why Chris knows everything and Rob knows people who know everything- so much respect for Chris 👍🏼
Knowing when you're out of your depth and getting a specialist is one of the best skills to have in life in my opinion.
there is a isolation fuse under the rear seat or in the boot, completely safe to take out, which could be the high voltage fuse its throwing up a fault for. i would try that before yous send it off.
I just want everyone to start understanding there is nothing magical with these hybrid or electirc cars. I drive an 8 year old tesla and you know what, all the DIY things i used to do on my other cars is no different on this car. Comes with same suspension components, same brakes, same steering and tyres. Yes drive unit is different. As for hybrids, I would start with checking the high voltage fuse. Check that and diosconnect it. Then check thge hybrid control unit. If everything is actually plugged in (plugged in with a click, try pulling on the connector). If everything is plughged in then reconnect the main fuse check again and only then send it to chris or any other more specialised guy. No need to be afraid of these thiungs, just dont tounch non isolated vires if you see those. Remember that these cars are meant to be driven in the rain, just like any other car
I’m putting my money on the inverter. Porsche hybrids are the same. AC stops working, dealer says you need new inverter at a cost of £6k and all it is is a fuse inside inverter that costs £3.50. But dealerships won’t open up inverters, too lazy to undo about 12 bolts. Independent garages do it.
I think you’re right, those inverters can be reasonably priced too, especially if you buy used.
Been doing A bit of research out of interest and it looks like you'll need a new HV Battery Junction box because the old Aircon pump will most likely have a short circuit and will have blown either one or both of the 30 amp fuses which then stops one of the start relays from energising . The old pump can be tested with a ohm meter to see if it's shorted. a low ohm reading would indicate a short . Looking forward to seeing follow up video on this one . Why are manufactures putting all components in expensive boxes when replaceable fuses and relays would suffice only reason I can think of is greed. Best of luck lads and I'll be sticking to my Gas guzzler for as long as possible.
Yes it’s got high voltage but it can be isolated. Maybe it’s time for you both to go on a course to learn some new skills 😊
This is the future people, You won't be able to change anything yourself and pay high prices for repairs.
I’m a London cabby my Taxi has a similar system. It is not uncommon for the HV fuse warning come on the dashboard. In my experience, this comes on when driving in pure EV mode with the heater on at slow speed the system seems to be overwhelmed by the drive and heater. In my opinion (based on absolutely nothing), the car is being driven during the winter on lots of short trips with the heater on and the battery has just become completely depleted. I would look at quite simply trying to get some charge into the EV battery
The garage couldn't fix it, "but" wanted to buy it ? I smell a fish.
Something I was told of when I did some basic level EV and HV System Training was that on some cars the Service Plugs can have a tenancy to somehow be 'knocked' or 'nudged' out of their correct secured position. It is worth locating the Service Plug and just visually checking whether it is correctly fitted and/or secured in it's holder correctly. If you feel it s not then get someone who is Certified to check it themselves and re-connect it. On my EV and HV System Training I was told by an ex AA Breakdown Technician who instructs the EV Training that the earlier Toyota Prius was notorious for this when they were new as the Service Plug is/was located in a place in the boot that was prone to being 'nudged' or 'knocked' out of place and thus causing exactly the same problem you two are experiencing.
Clearly if the garage wanted to buy it they knew what was wrong. IMO wanted to get it cheap pretending they couldn’t fix it!,
Agreed!
This was my suspicion! Why else would they offer to buy it!!
"We're not about negativity" in the youtube world of clickbait and drama it's refreshing to hear and just focus on the car 👍
Yup and don't know if related but police car in the background so could be some proper argy bargy.. like these guys atitutude keeping on topic and keeping hassle off the channel
Sounds like the garage owner had designs on that motor. Makes you wonder that they’re isn’t a lot wrong with it. Keep a close look out for stuff unplugged 🙄 maybe HV fuse ?
Totally. My first thought too.
When I first subscribed, Rob didn’t even want to be on camera, the way this channel is evolving it’s absolutely going to fly, good on you chaps.
A good buy you two.
My thoughts are that the garage you collected this car from knows what the fault is and was trying to buy the car to make a killing, hence the slight hostillity.
I bet you two will OK out of this project
Hi Rob and Chris my mate had one of these it was showing loads of faults. It turned out to be that A loose or corroded connector between the ECM (engine control module) and the TCM (transmission controller module) can cause erroneous data signals to be sent to these components. This can cause them to malfunction and produce abnormal symptoms in the vehicle.
They cleaned it up and all faults disappeared. It was just covered in green corrosion from a lose connection.
My mate fixed it and then sold it on. Great video as always. 👍👍
My mate fixed it and then sold it on. 🤣🤣🤣
I think the guy at the garage new exactly what was wrong with the car and was trying to shaft the owner.
Was just about to say the same, as why would you want a car that you couldn’t fix for the customer 🤔
Simple advice, keep away from Orange cables, and don't eat yellow snow. Best of luck.
Good place to start. There’s a High Voltage Service Plug under the parcel shelf. This is the high voltage disconnect plug. Check if that is either removed, in place or blown. 👍🏾
I saw Jesus one day when i shorted out the battery on my tractor, i recon you would see God if you shorted out the battery on that boys.
You were correct in assuming that the AC compressor runs off the HV system. In changing the AC compressor, I assume the installer has somehow shorted the feed to the compressor, as it is a permanent live to the unit. This would have intern popped the main battery fuse, located in the centre of the battery (being the rear seats, I believe the seat back comes out to expose it, potentially a small part of the boot load area) the recommended PPE for change a HV fuse is insulated gloves and boots, you should be okay as long as you're sensible, but changing that will allow the main engine system to operate again as it's a fail safe to prevent the battery exploding with the engine running (as that automatically starts charging it)
Let me know when you've done it and I'll claim my complimentary pint 😜
I'd also potentially chack the HV relays. If the polarity was reversed upon ac pump install, it would have melted the relay first before the fuse popped instead of the normal way of the fuse being first to take the brunt
HVAC isn't high voltage air conditioning.....its heating, ventilation and air conditioning
Good video and Chris was deep in thought 25:35 breaking it down just like a good service tech. Step by step and work the puzzle. Hope we get to watch diagnostics on this one. 👍🏼
Yes be ever so careful guys I’m not to clued up on these I’m trained on Toyota/Lexus Hybrid synergy Drive and they have a service key in the boot that renders the HV system dead so you can work on them safely,good luck guys.
Really enjoyed this video guys. Surprising how much you learn just watching and listening. Keep up the great content 👏
HVAC, Heating Ventilation & Air Conditioning 👍
Rob, while you're worrying about how long you're spending on the fault analyser, I suspect most of your viewers - me included - are enjoying trying to figure out where the fault may lie. So don't worry too much about the interesting process of fault finding. Always good when you & Chris discuss possibilities.
Brilliant video as always, really sparked my interest in the workings of hybrids as they are very current now.
Can't watt for the next episode on this 👍👍👍
I thought that HVAC stood for 'heating, ventilation and air conditioning'?
Interesting stuff Gents, I agree with Chris in that it can be a sort of chain of events but not the obvious. All I can say is one of my friends has a Toyota hybrid. It starts with the electric motor and cruises up to about 20 MPH before the engine cuts in then the engine will cut below a certain speed. I will just add that the electric motor assists with the braking and in doing so charges the hybrid batteries. That's probably no help whatsoever but that is all I can give you! Good luck Rob and Chris this could be a real adventure. 👍👍
Two gentlemen working together in harmony, complementing one another, is always what I enjoy about your videos. Like you both I am a car lover, but it is how you work together seamlessly, is just wonderful. From Brisbane Australia.
Would it be worth at least 1 of you getting some training on the Electric side of cars? As time goes on you will get more of them, plus if you can work on them you might find there are some bargains as not many people can work on them? Good luck and it will be interesting to see where you end up with this one.
Thats very strange for a garage that is supposed to be fixing a car to say they cant and then offer to buy it!🤔
Because they know the issue and is a easy one
Lovely looking motor.looking forward to seeing what the issue is and hopefully fixing it. Top work and thanks for the video take care
Love hearing Chris talking love the waffle keep up the good work 👏
I reckon if the dealer wanted to buy it for a stupid price, it must be a relatively easy or low cost fix!
thats why he was angry lol be easy to fix i bet
@@Luckyjo21 Or maybe a free fix if it's on a recall list.....
Quick check of the isolation fuse would be a start tbh ,maybe garage created a fault to get the car
But before that don't buy it in the first place!!
Just a thought to look at, should be a high voltage fuse (service plug) on the EV battery itself. I doubt the previous garage checked this as a bit of a job to check it out. Worth a look!
Renault EV tech here, I suspect all those faults saying the same thing (engine/hybrid electric system) is due to your diagnostic tool not having all the information. If it's anything like the cars I work on, you really need a Nissan diagnostic tool because that will tell you which fault to look at first (as Chris said one fault can cause several systems to give red herring fault codes) and also provide guided diagnostic procedures. You're right though, some EV's use the air con to cool the battery, although that doesn't necessarily prevent starting.
Very interesting as this is the future. Can’t wait to hear what Josh says. Hopefully it is a quick fix as that is a lovely car.
Usually HVAC is heating ventilation and air conditioning, not high voltage air conditioning.
Good luck.
My daughter has one of these cars and it is brilliant apart from when she had a wheel bearing, which contains the wheel speed sensor replaced. the replacement was a pattern part which was then replaced with an original part and all faults were cured so it pays to use oem parts on these cars.
Very interesting stuff guys.........
Just amazed at how far Chris has blended into your channel.
Camera , miced & talking......
Well done to you both 😉
Well done guy's take to the trained expert really looking forward to seeing the outcome 👍
Great to see a hybrid on the channel, looking forward to the fix.
Looking forward to how you progress with this purchase. Keep the brilliant videos coming guys you doin great job !
Can’t wait for part 2 hope you can fix it, very interesting!
If the garage wanted it I'm thinking they know or caused a fault Rob and Chris. Good luck with it 👍
Great content guys can’t wait for the next one on this vehicle, will be interesting to find out the issue with this car, now maybe the time to get trained on ev’s as there maybe more money to be made on this type of salvage ? Or you stay clear !
Brilliant video Rob, Chris please never change how you do these videos. 👍👌
Hello Rob and Chris, this will be an interesting project. Thank you for taking the time to upload another video. Ged.
There are some problems that just don't seem to be logical or rational without a degree in computers. My old B class ( 08 ) went into 'limp home mode' intermittently. Checked on the internet ( owners forum ) and the options were ABS sensors or brake light switch. Swapped in a new brake light switch and it cleared the fault. Who'd have thought that off the bat??? There's likely an owners forum for these Infiniti's, might be worth a check out!! Great to see you branching out, but remember to be very careful. Best of luck sorting it out, it's looking tricky.👍👍
Yep. Had an abs issues, with steering erro, couldn't read fuel, no speedo readout, engine code, and no ac working, all because I had 2 failed speed sensors. Mechanic told me I need a new brake computer but searched forums, change one, then a second speed sensor and all clear des gone car runs fine. They need to use deductive reasoning to solve this.
I'm going to follow this with great interest - I can see this being a new learning experience for you both. Get yourself on some hybrid courses! However... isn't 'HVAC' just 'Heating/Ventilation/Air Conditioning' or is it related to the DC/AC inverter that drives the motor?
Really interesting video and looking forward to the diagnosis and fix. High voltage terrifies me too.
Great video. I've never had an in depth look at a hybrid car before. Really looking forward to seeing how it progresses. 👍
I am not in the car trade but It is surprising how many people I come across in my day to day life who watch this channel. I bumped into a bloke i used to work with, I had not seen him for a good few years it was not long before we started talking about cars, and he watches this as well.
It's an awesome channel
@SI these guys know there stuff I watched it from the day they went to pick up the ferrari up and every episode has just got better and better ,well done guys
Think Chris needs to get himself on a HV course sooner rather than later. I don't agree about staying in your lane but agree its sometimes best to ship stuff out to those with the right diag tech, skills and who might do this everyday. By this I mean with the ICE cars you fix at least you are able to do the diag and then decide whether to do it yourself or ship it out to someone more specialist, i.e. engine rebuilds, air bag module resets, key programming. With the uptake of EV's in the coming years there will be a lot coming onto the 2nd hand market with faults that lots of garages won't touch and could be easy money to be made with the right knowledge and skills.
Yep, safety first. Let’s (get Josh) to get involved!
As Chris suggested, one fault can be masked by something else - at the end of the day it’s just a different set of parts which still form a logical chain, and can be fixed. Good Luck guys!
Great content guys,be interesting to see how this goes, definitely the right move to stay in your lane
Really enjoyed it dont say sorry about the waffle was good to hear Chris 😂 be good to see how this one plans out and let's hope its a cheap amd easy fix 😀
This is an exciting video, can't wait to see the outcome.
Excellent video guys, I'm so looking forward to the next installment on this one
Thanks for another interesting film. Hope it's a quick fix
Chris's waffle is superb, best of luck guys. It looks like a great motor if you can fix it for a price.
So the guy in the garage couldn't fix the car but still wanted to buy it and got angry when he wouldn't take what he offered. That seems legit 😂😂😂😂
Unplugged brake switch?
Doesn’t it 🤔
he knew exactly what was wrong id say , probably a scammer.
I know right🤔I know Rob won't say where or what the garage is called but he should do to warn people to stay away as sounds dodgy as
It's refreshing to see these new style vehicles along with bikes, boats, jetskis, campers, Ferraris and Fiats. Really pushing yourselves. Still loving the channel guys.
Maby way off but the clocks and screen look same as j11 qashqai and when they flag up with the chassis fault and other things it's related to the battery/charging system qashqai are known for it the car disables all the safety systems if it has a voltage issue
Best leave this one to the experts, we don’t want to hear Chris Chris Chris and the fire brigade turning up💪
Great video, that shows the difficulties faced in the transition to EV technology and how the the skills base of experienced and talented folks well skilled in IC powered vehicles, is challenged by the maintenance of EV technology, involving life threatening voltages. Hands off if you don't have the knowledge and training sounds like the safest option!
Hi guys,sometimes the relay for the high voltage system can fuse together if there’s been an issue,I believe if you can find where the service plug is for the high voltage system the relays are around that area.
Might be a good shout 👍🏻
Very interesting subject, can't wait to see what happens
My mate has one of them and he's had no end of trouble with it far to complex every time it has to go to a garage and the bills are unreal good luck 😮
check the flux capacitor lads it could be that but im no expert
Very interesting analysis for the uninitiated to watch listen and learn from, thank you
The high voltage fuse is normally near the HV battery. Also check the HV service plug, it also has a fuse in it. The HV battery is what starts the car so it won't start if it isn't working no matter if you have 12v supply. On the other hand, a bad 12v supply can affect the HV battery or other components which will revert to fault the car. all the best.
A friend of mine had a Toyota hybrid with the same fault and Toyota replaced the battery control module under warranty although the car was out of guarantee
It’s brave new world, I guess a lot of people are going to have to do some safely training and get certified even to do their normal jobs which are not directly related to the high voltage parts of the system
Our Nissan had a wire in the wiring loom split near the battery tray and that caused similar issues .
Some great advice so far guys, good luck with this one. I hope its not going to be to expensive though.
I would jack it up,and do a live reading on each corner (abs) sensors.
Very interesting, can’t wait to see the outcome
I might be tempted to put an oscilloscope on the CAN bus and just check for normal patterns to see if a control unit somewhere was dragging the system down. If it is then you would need to unplug units or inspect the circuit diagram to find a way to trace.
Check the alternator/generator, and those replacement adas cameras can cost an arm and leg from Nissan including installation.
400 volts… you just don’t see them coming ! What a line it’s a belter
Shocking ⚡️
Nice looking car hope you can get to bottom of it.
Yes you are correct in not messing with orange cables but there is a HVIL or High Voltage Inter Lock system in the low voltage side which would open the EV contactors if you did remove an orange cable without doing the safety power down of the car first, like you say your not trained on this so best to get a specialist involved. 👍👍
HVAC system does play a part in the EV system as it uses that to cool EV battery.
Airbag system also involved in EV system, if it see a crash signal it will open EV contactors.
You are seeing a EV system fuse fault, this would be inside the EV battery I guess and if that fuse has blown then what blew it?
Be interesting follow up on this to see what root cause is 🙂
Any loose change in there Chris 🤣
A whole new infinitely complex system to play with!! Good luck and good work guys!!
I love electronics and there are basic principles to follow. To bring me up to speed on a hybrid system, I would spend time knowing how all these components allow the engine to produce electricity to fuel the batteries. I would expect a voltage controller would come first. This will be fused. If that fuse was blown, then I would expect the controller has failed. I charge my car battery via solar. The only item in between is a charge controller which regulates 21volts input from the solar panel to 12volts.
It's comforting to know that if you get it wrong you will get a free perm!
This is the start, Rob will have to go on an EV course now. Don't be afraid to change lanes and never stop learning. Great video, very interesting.
Although these cars have the big RUN battery, they still have an ancillary to start the engine and to power the electronics for normal running just like a conventional car. However, the ancillary battery also runs the computer management system of the engine and the electric RUN motors and could be the problem. Great video as always Guys!
Very interesting subject on hybrid cars looking forward to the next one 👍
interesting video but the hybrid looks incredibly complex - not for the average Diyer I think. I had wondered about looking at hybrids when I change my car but looking at the complexities of this thing and the expense think I'll stick to petrol whilst I still can!
Infiniti owner here, they are brilliant tbf, classy, rare, loads of tech, different. Dont tell everyone!
Sincere sympathy buddy, hopefully it won’t happen to you!
Interesting this one guys, looking forward to the follow up video 👍
Superb video Rob & Chris chatting was brilliant 🤩 Good decision asking josh 👍🏻 Hopefully we’ll get a part two 😀
Another very interesting video Lads ,a real learning curve!,give me plugs n points anyday!!😂🇮🇪
