Warning Light

[Bill M]

Hi Gabs/Rojie,

 

I'll check the Proscan out.

 

Back to your message re the Inverter, the one you refer to is the small inverter which produces power for the 100Volt outlets which you rightly point out has a fan as you'd pictured. I have checked that one yet but I will and let you know how I get on. I hope it's not as tricky as getting the battery fan out!

 

Cheers.

Look like no luck with resolving the issue, my 2004 hybrid start showing same wirning lights: 4wd,vsd,orange(!), red car with (!), management light. Car starts and drive, the theory with tyres pressure make sens and I will check them. What make me think, when car is stationary or slowly move there is only management light and red car with!(!) are on, just when get 10-15km/h rest of the worning lights appear. Will check tyre pressure tomorrow and share results. Cheers 

[Darek]

Hi all, checked tyre pressure but no difference, checked abs sensors (same values for all wheels). Looks like warning lights come up after start to acceration or deceleration, I suspect acceleration pedal but values change on live data when press and depress the pedal, also suspect angle sensor because values stay constant 1150 on live data no change when move steering wheel. 

Managed to read fault codes and live data by autel maxidiag 808 Pro, 

- p3125 inverter mulfunction

- c1259 HV system regenerative mulfunction 

- c1310 HV system mulfunction 

Last two disappear after swith off and switch on the ignition. No codes for acceleration pedal or angle sensor. 

Car starts and drive with warning lights but with limitation to 60km/h. 

Any one know how to test the inverter? Not the one between the seats, the one under the bonnet on right side.

Not an expert on Hybrids, from what I understand, if the hybrid system has been functioning optimally back in Japan, i.e. it has been utilising the electric motors the majority of the time, it is possible that the cooling system for the battery is not working as it should - you may need to get access to the fan blower that keeps the battery/aux battery cool - if these reach a certain temperature, it will cut off the hybrid system.

 

Coupled to this, is the loading of the Electric motors, could reduce the loading on the petrol engine - what condition are the spark plugs in?, and potentially the operation of the catalytic convertor at reduced heat levels could require it to be cleaned.

 

I got this info from: https://www.fixmycar.pk/toyota-alphard-hybrid-e-four-2/

 

I think there may be some diagnostic info in the online maintenance manual I posted up a few days ago (its in japanese though)

 

[Guest]

Same problem with mine, was fine for months, now cuts out randomly. Tried a Toyota garage and they couldn't read any codes, tried new 12v battery, checked tyre pressures and no luck.

 

It's got worse over time, at first it was cutting out very rarely, now it might go for a week fine, then next day cut out every half a mile.

 

Surprised we can't even get it diagnosed

Hi all

I had consultation with few hybrid technicians and possibly one or few hybrid batteries are bad and they have to be checked, replace if needed and all 28 hybrid batteries have to be recharged and balanced. They said it is common procedure for older hybrid generations no matter what mileage they have. I will take mine apart probably naxt weekend. Cheers

HiRight there I have a we update, I manage to get teachstream from ebay and diagnose the car again, find on freeze frame :

P3125 inverter mulfunction

And subcode 472 

One of the guys had same problem with same codes, and suggested to replace current sensor for rear motor what I did (order from Japan) and problem solved.

Car drive like a dream again. 

 

[Gabs]

That's great news Darek! Thanks for the update!

Could you please let me know where did you manage to find the specific part?

 

And also, I'm always afraid of touching the inverter given all the high voltage warning, would you also give any advice on that?

 

Thank you very much indeed mate

Hi

Two months ago I didn't know much about hybrids but after hours of  reaserch, I would say I can do it /fix them or diagnose. 

Megazip that's the website where I ordered the parts, two other pictures are from website where you can find parts number. 

The high voltage system are easy to workout, first you have to disconnected the 12v battery (negative first) take off safety plug (on the back of the passenger seat orange plug) the best put it in the pocket. Then you wait least 30min. To give the time for decharge the capacitors. When you open the inverter/converter the best double check if the power are disconnected (using multimeter and measure DC voltage) should be 0.

But before you do anything, diagnose the car with teachstream or other compatible device. 

Cheers

Hello Darek

Thank you very much for taking the time and all the explanation mate

 

Can't pull the code unfortunately, but freeze frame shows P312563

Not sure if the 63 stands for the subcode?

 

I've just managed to find a second hand inverter online for 500 quid so I've decided to just try my luck on that

 

Will take it to my local mechanic tomorrow to get it changed and will post the results here..

Hi if you know the inverter are 100% good, that's fine. Not sure what 63 sub code means, usually is tree numbers (can you post freeze frame picture) but will be good same time check the inverter pump and radiator if is not chocked, my pump was running but radiator was blocked and that caused the problem with inverter, simply overheating and coked electronics. 

 

Good luck and keep posting.

Hello mate.. I've just realised my mechanic appointment is only next Tuesday, got the days wrong!

 

Unfortunately I have no idea hows the inverter I bought, the mechanic that sold it to me said it was from a running car, but yeah my car is also running but just not really well.. I've opened it yday and it seems in pristine condition inside

 

Where's the pump located? I've noticed the car is constantly making a noise as if there's something trying to switch on ( almost like one of those boat engines that you pull the cord trigger to start)

 

And is the radiator the main one? Or do the inverter has its own? I've had to change my radiator not long ago as there was a leak, so it did stay quite dry for some periods (although I was always topping it up) , thinking now that it might well be something related to it, as you said, something might have cooked inside 

Follows shot of freeze frame

Hi can't find anything on that code, you can try check live data on hv control system and hv battery and see if you have anything abnormal . 

The pump is on passenger side under the bumper attached to chassis leg, if you take off bottom bumper panel you will see it and radiator, alphard got only one radiator but bottom 1/4 of that is dedicated to cool inverter is like 2 in 1. Pump on the picture is from Prius but Alphard is similar just side hose attachment are moved 180°.

Hi folks

I have had a problem with my 2003 Toyota Alphard Hybrid, which was imported and converted into a campervan four years ago. It has been running fine for four years, but then warning lights appeared on the dashboard, identical to those experienced by many on this thread:

VSC light (orange)

Exclamation mark in circle in brackets (orange)

Exclamation mark within car symbol (red)

The car felt sluggish to drive, very slow and, very worryingly, the car suddenly without warning lost power on four occasions. I was fortunate in being able to coast into safe areas.

 

I had a massive problem in getting a diagnostic test done on the car, as it is relatively old, an import and a hybrid - six local garages didn't have the appropriate equipment.

I finally found one which specialised in Imports, and their diagnostics identified five error codes:

P3000 Battery Control System

P3108 Communication fault (Air conditioner > HV)

C1310 HV System fault

P3006 Batteries levels unusually different

P3022 Battery block 12 weak

They tested the 12v battery, and that was fine. They advised that the above fault codes indicate a fault with the High Voltage Hybrid battery system.

 

The next issue was to try to find a way of remedying the problem. My own research pointed to the fact that a high voltage battery would cost THOUSANDS of pounds. I was obviously shocked and not a little bit fed up about this, and totally unsure of the way forward. After extensive research on google, I came across a company in Glasgow which specialises in replacing the existing Alphard HV battery cells with reconditioned and rebalanced Toyota Alphard cells, at a fraction of the cost of new ones. This necessitated getting the car up to Glasgow (I had a breakdown relay agreement with breakdown business which takes car to any UK destination), and the job was completed last weekend, and the car runs like new, plus it has a 3 year or 30K warranty on the reconditioned battery. Job done, the car runs perfectly, and no warning lights. I can't praise http://hybridbatteryrepair.co.uk/ enough. Fraser is exceptionally helpful.  See also their google reviews and their facebook page - they speak for themselves!!

Fantastic stuff mate thanks for your update! Can I kindly ask you roughly the cost of it?

 

I got my problem sorted by changing the inverter ( forgot to put down an update, no lights, car running well enough but still think the battery is not top notch as it discharge quickly and takes ages to recharge, something I didn't experience when I bought the car) but still interested in having a look at the battery cells..

Around London people want upwards of a grant so pretty expensive since my one been running okayish 

 

Cheerio and many thanks to all the folks that are always happy to share some knowledge!

It was myself that rectified the issue for John.

 

Apologies in advance if this post is not allowed, I did try to find wording which either excluded or included trade

 

If someone could confirm please then I can post more details 

 

Thanks,

Hi Darek

My name is Virgilio and new to this great forum. not too sure if you will receive this question of mine. My Alphard Hybrid 2007 E-Four, once switched on the engine will start but just for one cycle. We have P3125 with Code 3000 trouble code and also a code 484.  Is this the same issue with your Alphard? Do you think the current sensor will resolve mine too. Thank for the great help in advance. Or any possible suggestion?

[tech68]

Just for info, im looking at one here: no codes & using a japanese s/w programme to code read, LAUNCH x431 upto date s/ware, you wont get UK TOYOTA import support as IMPORTS are not for this country if that makes sense, hence peopls saying toyota could not read etc.

 

I'm still to look at live data values to see what the tool covers.

Ref: DISCONNECTING HYBRID SYSTEMS - after removing ORANGE HIGH VOLTAGE CONNECTOR WITH HIGH VOLTAGE GLOVES, after the waiting time you should also be carrying out voltage checks wearing HIGH VOLTAGE GLOVES & use a meter capable of high voltage reading and making sure you carry out AC & DC VOLTAGE checks correctly. . If the capacitors have depleted by the waiting time, you wait again.

 

If unsure of what you are doing, dont be surprised - if you change/replace and then go to your local toyota garage & say please reset lights etc, they may say no etc.

I bought this unit and it worked flawlessly with my 2003 hybrid.

Hi,

 

I'm a recent Alphard owner, bought 2005 2.4 Hybrid E4.

 

Great machine, but I have also experienced the same problem. Amber VSC, Exclamation, and red car on lift light. Loss of power and cut out. I tested with a launch that gave me a low voltage on the 12v side and C1310 HV System Malfunction. 

 

The 12v battery was low, I disconnected the battery and the fault left. Driving fine, but another cold morning has brought the fault back. 

 

I know it needs needs a new 12v battery and that is my next step. If the problem persists, then what I gather from the thread so far is it could be few things.

 

1) Inverter

2) HV Battery cells

Any further updates would help a lot. Maybe an indication of repair costs, as I might have to give the car back if it's too expensive.

 

Thanks.

You need to scan the car's systems.  the red car icon is only information about an electronic error.
