Malfunction Warning!!

[152bobby]

Just came off a roundabout to get onto a slip road to M3, put my foot down to accelerate, car felt like it braked for a second and then I got Blackpool Illuminations and beeps on the dash.  Everything is coming up as Malfunction.  Crash Detection, Parking Brake etc.

Stopped at Services, took these photos and turned the car off.  All lights have went off except the warning triangle and the Visit Your Dealer warning.

I'm still driving on.

Anu suggestions to clear this message.

do not clear any codes take it to the dealer, if it has a certain code they will replace the engine damper

Ok, I'll assume it's still ok to drive, because it's not telling me to stop.  After turning the car off and then on, it reset cleared more or less everything itself apart from the warning I stated and a triangle.  Why does this never happen when I'm popping to the shops and Toyota are open and up the road !!

I'll pop in and see them on Monday.

Did it drive OK?

[152bobby]

Yes everything seems fine and everything is working.  The MyT app shows this..

As mentioned this may well be an engine damper issue, it will store a code, get it checked out at your dealer

Murphy's Law.

When you were accelerating hard have you hit any pothole or cracks on the road ?
This is the damper thing and can happen in certain conditions. In some cases thete is no need to replace anything and the car is perfectly fine to drive, in others the issue may return shortly after reset and then you will need a new damper clutch replacement. 
You can run your own diagnostic if you are interested but since your car it’s under warranty just look at the codes but do not delete anything. All that been already suggested. The car itself will not delete any fault codes . 
You can drive it , don’t worry about that.

No potholes etc, I just accelerated.

I've lost my OBD reader, I was meaning to just get a simple replacement one for my own interest.  And as advised, I'll not erase the fault until Toyota have seen it 👍

You can buy Carista from Amazon. These are good quality and give you wide range of options to adjust settings or diagnostic runs. 
These adapters if you subscribe to unlock full version with their own app you can diagnose a lot of things where simple scanners can not. Worth every penny.

That's been mentioned before, but my question was never answered...which was, "who has one that's being used on a YC or any Toyota" and which one do I buy, there's not only one !!

Had exactly the same a few months ago. Made an appointment with the dealer, next day for a quick look, got in the car and all was fine, no warnings, all gone. Still drove to the dealer who said if its gone we can't see what went wrong, must say a bit of a surprise, but none the less have had no problems since. Hope you are as lucky.

Right, I've just had the car parked in my garage for about 2 hours since a drive back from Southampton and then I drove to the local shop and there's no trace of the malfunction, it's all gone.

To be honest this is pretty annoying and Toyota must be well peeved off with people popping in all the time.

So if what you say is true(and I'm sure it is), it's pointless me going to Toyota?

I had the same thing happen to mine when it was still relatively new - Had just floored it to overtake a moped on a country road and when I lifted off got the ol' Hybrid System Malfunction disco.  

I stopped at a services and turned the car off and on again and that got rid of most of the cycling litany of scary messages except the Hybrid System Malfunction one, but being me I immediately tried to trigger it again by accelerating hard and lifting and driving really fast but it stubbornly refused to do it again  

Took it to the dealer the next day (And I was surprised they actually looked at it since it was a saturday and I wasn't pre-booked in - Normally they'd make you book in advance even for a puncture! ), they reset the code, and hasn't come back since, despite me continuing to drive like a hooligan  

Annoyingly this was before the Damper Replacement campaign started, and because they didn't record the error, just reset it, they now won't replace the damper unless the error happens again, and it stubbornly refuses to despite my best efforts  

 

It only seems to crop up on earlier built vehicles - Allegedly, in stereotypical french fashion, they didn't tighten up the damper assembly enough, but almost everyone who's had this problem only gets it once and then the car's fine - It's almost like that small slip somehow tightens it up  

 

It's interesting the code has gone from yours - Despite turning mine off and on a few times and it standing overnight the Hybrid System Malfunction error wouldn't go away and kept overriding the MFD display (Very annoying!) until they reset it. I wonder if there is some sort of timeout for it...?

 

It is a bit shaking to the confidence in the car, but if I can't trigger it again despite my best efforts then you should be okay  

I was going to try and force them to upgrade the damper but, given my past experiences with my local dealerships, I don't trust them to put the car back together to the same standard as the factory, so on balance I think this is for the best...

Absolutely. Too often problems arise after something has been 'serviced'. Weighing the benefits and risks is always worth doing. 

Much like deciding whether to have an operation in hospital really.

[flash22]

All I can figure is that is torque and/or heat related as it does it under heavy load, the car freaks out as the engine speed does not match what the gear box is expecting (for want of a better analogy the engine is overpowering the gearbox)

[Cyker]

That was the original theory, but it's what was weird in my case - It triggered *after* I'd done a hard overtake and had lifted off to coast back down to cruising speed, so the damper should have been under the least stress.

For some posts I've seen, some people were just cruising on the motorway or a dual-carriageway and it just happened out of the blue.

Very odd; TonyHSD reckons sudden shock from e.g. a pothole or some such can trigger it and it's possible that a combination of that and something else causes it, but it just seems very random!

On the bright side, it seems limited to earlier models (20-21, maybe very early 22; Certainly not heard of anyone with a post-facelift experiencing it) and for almost everyone I've seen who's had it, it only seems to happen once then doesn't happen again. A few people have had the damper assembly replaced but the lead time seems to vary wildly, with one person waiting literal months with no word and no car.

Given how hard I drive mine, I'm fairly confident that if it was going to happen again it would have by now.

[TonyHSD]

The damper will slip only in excess torque is detected between engine and the PSD. This event happens under heavy acceleration, or when traction control is activated, drive over bumps, cracks etc anything that can activate TC and engine will override the max allowed speed of PSD. 
My car had recall for ice update to preventative exactly this from happening under heavy acceleration. Even so few years later the car did it, and it was definitely because I hit a pothole and the engine revved up to very high rpm, I never seen before and then all went quiet , the car went into N and all the lights came on. After restart the car was ok but with the warning lights ON, which I reset with Carista and never had any issues ever since, now 100k miles later. 
For the Yaris recall of damper clutch the issue was because of possible contamination on the friction plates in factory that can cause eventually slip and hybrid system malfunction warning. 
I remember also that one member reported here bad smell clutch from Prius gen 3 and after investigation it came up as bad clutch friction plates , it was fixed under warranty. He mentioned here and everyone was laughing at him saying there are no clutch in these cars, acting there is but it is not functioning like engage and disengage, it is always engaged and acts as damper and allows slip better engine crankshaft and psd when excess torque between is detected, otherwise the engine or the transmission shafts can break. 👍

[flash22]

mine rarely comes out of eco and no more than half-throttle, but I do have my moments

MG1 and MG2 overspeed ? as the input from the engine drops, it still has the stored mass/torque in the gears (3-way planetary and diff )
