Excellent resource!

Pinned!

 

A very informative piece. Very well written to explain in layman's terms.
I actually found out when I was researching buying my CRV. There was a lot of speculation on the net regarding what year the dpf was introduced onto the CRV diesel in UK.
I previously had a Civic with ictdi engine minus a dpf. And it was one of the reasons I purchased an 09 ictdi rather than the idtec engined one. Its something less of an issue in my opinion. Although lots of idtec engined owners report of very few issues with dpf. And as it suggests within the dpf forum write up the Honda dpf is usually very reliable.
Although after purchasing the CRV I thought I'd made a mistake after seeing the Lings Honda diagram showing a dpf. But after more research I found the info to tell me it was introduced into the UK CRV on the idtec engine.
Thanks again UK-Kev.
I'm sure it will help a very many Honda Crv owners.
Kindest regards
Rich.

 

It is possible to do a force regenerate yourself with a scan tool, I used this one to do a forced regeneration

Launch CRP 429C

Foxwell NT414 OBD2/OBD II Scan Tool

Would that work on an i-DTEC engine?

 

CR-V EX I-DTEC

reporting that it can, and I did it myself - worked fine, and saved me a garage trip

I also used it to reset the SRS codes, what I found was the cable connector underneath the passenger seat was not 'seating' correctly form the seat being moved backwards and forwards. I got the solution from youtube, basically use a simple tie-wrap across the connectors after cleaning them, to stop it moving again. No issues from that since.

 

Sorry, I had two scanners, the one which I used to do the regen was the Launch 429C, I have edited my old post

Apologies for the confusion

 

Great info - thanks for providing this.

 

off to the dealer to make sure my car has the updated DPF data on board

 

thank you so much for sharing that document

 

"At less than 7g the DPF system will automatically clean itself whilst driving once the DPF is up to correct operating temperature " - this seems to never happen in my car. It has plenty routes of perfect condition for DPF regen. I am driving 25km to work and 25km back and this is not a city traffic at all. Yet the car is always waiting for PM to be 10.5 and then it will start regen. Sometimes it is lucky and this happens when I am on motorway or another fast route.

Sometimes not so lucky.

Today I parked beside workplace when there was PM=10.2 Next I needed to go quickly to the store during break time and car started regen after 2 minutes of driving, with cold engine, about 30 seconds after PM changed to 10.5

This is very silly especially that it could do it so many times when it was fully up to the correct working temperature. Some time ago I was observing it on a motorway. PM was about 9. My exit gas temperature was between 400 to 500 C and car did not start regen. It did it 2 days later when PM was 10.5

So I do not see any intelligence in this. It just waits for PM=10.5 and it starts regen. No matter of the conditions.

I know it, because I am driving with car scanner on for the last few months.

It never show me any warning about DPF, probably thanks to this that I am always looking on my dashboard in car scanner. When regen is underway I never shut it down until it is done.

 

A useful thread and a useful attachment, thanks.

Do Honda's "onboard" systems show:
DPF regen underway?
Historical records of DPF regen?
Current weight of carbon in the DPF?

Is there a forum thread comparing scanners? A bluetooth connection from a mobile phone to the ECU could be useful for "live" info.

Short answer, no.

 

For everyday live monitoring I'm using Vgate iCar Pro Bluetooth plug and Car Scanner Pro app on Android phone.
I can monitor everything related to DPF with it but most of DPF data requires setting up custom PIDs.
I do not know if it can do forced regen.
For this I would use HDS HIM. It is way more cumbersome as it requires laptop but it can do everything

 

Thanks Jack, I can see "Vgate iCar Pro Bluetooth plug " on ebay for £18. "Car Scanner Pro app" is described as a "free and safe download" from car-scanner-pro.

The "HDS HIM" module is approx £130 on Amazon or approx £110 on ebay, possibly both supplied direct from China.

Is there a thread or sub-forum on this forum that deals with monitoring / diagnostics ? I should be able to use keyword searches to pull up useful historical threads.

 

There was a thread some time ago where there was a really good full scanner, but I can't remember which one it was sorry.
