Re: Toyota Innova Crysta : Official Review

So a quick question to Crysta owners.

Like you all know, we got ours on 5th of October, finished 1000 km with a quick lunch break to Kolhapur, gave it for service and in a few days set out on our south trip.

We are in Bangalore currently and the car is at 3250 kilometers.

I have observed a strange thing, if its a usual thing or not, the folks here can correct.

When going over certain potholes or rumblers at certain angles, the steering makes a katak noise, its not always but only at certain angles, is that normal? Its there since day 1

Re: Toyota Innova Crysta : Official Review

Havenít noticed this in my past years with my crysta humyum.

Could you please check if the lever used to adjust the steering tilt/sliding one is tight? Could potentially be a very small play if itís not secured tightly.

In mine there is movement of steering wheel over rough terrain, but there is no katak noise, but occasionally there are mild thuds depending on the terrain. If in doubt get it checked at a Toyota dealership.

its a manufacturing defect of steering yoke excess play. In our family, one of the MY2022 fortuner got the same issue and the entire steering column yoke was replaced UWC (imagine <300km on ODO). Its not supposed to make any kind of rattles or noises. Apparently, its a known issue and TASS will not make a fuss on it. Please get it inspected when you are back home from the dealer you took it from.

Yes, it does look like some play. Its coming right from inside the cabin where the steering column starts connecting to the rack. I could replicate it all the time after you mentioned. Go over bad road surfaces at slow speeds and the steering will move left to right and the noise will come.

Going to book an appointment for this.

Also, because of this, it feels like the suspension is not all that connected to the car, I mean a feeling of something loose.

Remember, when they do replace the steering column, the system will need to be recalliberated all over again, as the battery will have to be disconnected. Since there is a capacitator which keep the current for min 15 mins or so, ensure that they keep the battery disconnected min for 30-45 mins before starting recalliberation again. Otherwise it will give error and wont let the system calliberate. Do post the final outcome.

Hi, just so that I am clear, its only the steering column and not the assembly they would replace right? Adding the Boodmo link just for reference.

https://boodmo.com/catalog/part-45250_0k100-39663757/

This one right? So nothing of the wheel alignment etc should change right?

Re: Toyota Innova Crysta : Official Review

DPF manual regeneration:


Let me state in the beginning that this was not an issue but rather an experiment.

It was quite a while since I experienced the DPF auto regeneration. I was out of country in the beginning of this month and my father had taken the car out on a 600km highway drive and told me that was the last time the car performed regen. After that we had two airport runs and a lot of in city runs. However I never noticed the regen kicking in. Also after switching to Xtra Green the regeneration frequency had noticeably reduced.

I just plugged in Techstream(Toyota official software) and noticed that the PM accumulation ratio was 75%. Yet there was no warning nor request to perform manual regeneration. Nor was the DPF button working(in my car it anyway doesnt show the DPF status when pressing the button).

Hence decided to perform forced regeneration through the tool even though this was not necessary. I just wanted to check how much the PM accumulation ratio would go down. The engine was cold since car was parked and hence the revvs climbed to 2k RPM for five minutes.

Toyota Innova Crysta : Official Review-img_3578.jpg

However there was not much of an increase in the EGT which is needed to burn the soot. However the PM accumulation climbed to 100% which I think is a way to fool the ECU to kick in regeneration by the tool.

Toyota Innova Crysta : Official Review-img_3579.jpg

After four minutes of revving at 2K RPM, the EGT was still around 250 deg C and no reduction in PM.
Toyota Innova Crysta : Official Review-img_3581.jpg

Then the revvs dropped to 1200RPM which is the auto regen RPM and this is when I believe diesel gets injected at the exhaust. That causes a rise in EGT and the PM ratio starts dropping down.
Toyota Innova Crysta : Official Review-img_3583.jpg

Here is a video showing the same: In five minutes, the PM drops from 100% till 8% aand the EGT climbs till 700+ deg C. This is when the turbo also spools up which was not the case earlier. A sweet howl is heard from the VGT.



After the regen process, the PM ratio was 8% with peak EGT at 710 deg C.
Toyota Innova Crysta : Official Review-img_3590.jpg

Then took the car out for a short drive to cool down the exhaust further. Not sure how but the PM ratio was further down to 2%.
Toyota Innova Crysta : Official Review-img_3591.jpg

Next time I will try to find out what number of PM ratio causes auto regen. I only was able to find out that 149% is when limp mode is triggered and regeneration no longer possible manually.

But just by guessing the duration of entire regeneration being less than ten minutes, I think the DPF was still working under its normal threshold to trigger auto regen. Generally the manual regen is supposed to last around 20+ minutes to be able to clear all the soot.

My crysta touched the 77777 km mark today, on NICE road. It was almost a blink and you miss given the open roads. I somehow managed to spot this milestone. Was not even tracking it, but was good to suddenly spot a milestone.

Toyota Innova Crysta : Official Review-mileage.jpeg

By and large, an enjoyable ownership. I was going through all the bills/service receipts ever since I took delivery of this car in 2018 (G trim, 7 seater, 2.8AT), and I have spent 103,331/. in service bills.

I mostly get about 11.5-12 KM/Ltr, in full tank to full tank method. I have diligently done the services exactly on schedule.

Only one problem for now - The front passenger seat belt doesn't retract smoothly, and its quite hard to pull and secure too. Have raised the issue, and Nandi Toyota will look into it in the 80K service.

I think my Crysta is all set for another 1.2L km. Fingers crossed.

Interesting, thanks for sharing!

Not knowing the PM accumulation is frustrating, and can cause unnecessary anxiety, esp given how a clogged filter can cripple the vehicle (in an extreme case). Here's why: there are times when the auto regen is triggered like clockwork every 200-225 kms of highway or even highway + city driving. And then there are times, it doesn't come on even after 350-400 kms!

Is it a function of driving style? Fuel quality? Weather?! Toyota should have used the vast real estate on the MID / Infotainment display to show the DPF and Adblue level.

Thanks for sharing the details. I presume you did this at ASC via specialized software accessible to service technicians only, and it is not doable otherwise. However, in one of the T-Shield videos released by Toyota, there is mention of a "software update" that would enable triggering of manual DPF regen irrespective of DPF clogging levels, and they recommend to do so before climbing to altitudes higher than ~4,000 m beyond which DPF regeneration might not occur due to lack of Oxygen. Any info/updates on that? Right now, manual DPF regen is a hit or a miss, and might not get triggered unless the ECU "thinks" that it is needed, and as seen from multiple posts here (and the Fortuner official review thread), it might be too late by then.

I thought there is a provision to display DPF clogging levels in all Crysta's manufactured starting Nov-2020 (please see screenshot below from Fortuner's owners' manual). Is that not so? This is the case with all Fortuners manufactured starting Jan-2021.

My June '22 Crysta has a Manual DPF Regen button. Is that what you're referring to?

You mean, auto regen?

Nope. You can see the level of clogging only when regen is in progress. Same with Adblue; Crysta starts showing a warning only when the Adblue in the car will last 2400 kms. And it then counts down the kms.

Yes - pressing that button will trigger manual DPF regeneration only if the ECU decides to do so. So, let's say your DPF monitor (which appears on the MID when you press that button) shows 3 bars, manual DPF regen will not be triggered. Ideally, auto regeneration should kick-in as soon as this goes up to 4 bars, but sometimes that might not happen and that is when manual regen should be allowed by the ECU, once that button is pressed.

No, I specifically meant manual regen, by pressing that button.

That is strange. In the Fortuner, you see the DPF clogging level every time you press that button - please see the screenshot I added to my post above. I would suppose that it would be the same in the Crysta as well, since both vehicles employ the same system.

Re: Toyota Innova Crysta : Official Review

I would highly recommend a scangauge to all BS6 DPF Crysta/Fortuner owners. It lets you do two important functions without a laptop.

1) Monitor DPF level using x-gauge function
2) Trigger forced DPF regeneration if button doesn't work.

Apart from that it can monitor various sensor values like EGT, DPF, Intake Air, Coolant Temp, Boost, Torque converter oil temp, transmission pan oil temp, etc and more. Some of this can be done using torque pro app too, but i like scangauge better.

I have one fixed on mine since 2017 but since its a BS4 it doesn't do BS6 specific readings and functions. I use it to monitor transmission temps mainly and to glance through other values like coolant, boost, intake air temp etc.

Its permanently mounted on the dashboard plastic trim. Bought a spare trim for mounting this and cable is routed from behind.

My understanding is: pressing that button triggers manual regen. And that is when it displays the level of clogging.

Is there a way I can see the level of clogging without regen being triggered? Saw a video where the vlogger pressed the button when the engine wasn't running - regen wasn't triggered as it does so only when the engine is running.
