Hi All,
been following this forum since I picked up a shiny new 2016 GX 2.8 Auto mid last year and after a year of benefitting from the collective wisdom here I've got something to contribute back.
*USE THE FOLLOWING INFORMATION AT YOUR OWN RISK (impolite yelling intended)
A manual DPF regen can be triggered on the Prado/Fortuner 2.8L by issueing the following CAN message at the OBD port 07E0 05 30 29 06 01 01 00 00
It also happens to work as an OBD2 broadcast message which allows us to send it via OBD2 devices such as the scangauge/elm dongle and apps such as Torque Pro that dont appear to support messages for specific ID's.
In the android Torque application a custom button can be created for this command containg the raw OBD command data 30 29 06 01 01
In the Scangauge a custom command/message can be added containing 3029060101 as tested by my good mate dave-c over on the www.fortunerforum.com.au forums.
The motor needs to be running and ideally at operating temperature prior to sending this command (just once). The idle speed will come up to around 2000RPM and the engine ecu will run a full burn (dealer style?) for 10-15 minutes. The fast idle appears to be to bring the DPF core up to burn temperature and will taper off over time. Once complete the engine idle will return to normal. The burn can be stopped at any time by stopping the motor and will not resume at next start.
This has been tested on precisely one Prado (my 2016 2.8 Auto GX - without the DPF ECU update) and precisely one Fortuner (Dave's 2016 2.8L Auto - with the ECU update). This is why I yelled at the start of this post that using this is done at your own risk.
I had two reasons for wanting this ability:
1. I wanted to be able to force a dealer style regen if I'm stuck in the middle of the bush with a clogged DPF, a Prado in limp home mode and a pissed off missus.
2. I was hoping to be able to control when DPF burns take place so as to avoid the "burning the Prado to the ground" scenario, which for example could happen in spinifex midway along the CSR, by instead doing a manual regen at a time and place of my choosing. Say on a nice patch of bare dirt at every second or so campsite. DONE :-)
EDIT:
After further testing we know a bit more. The automatic regen burns are triggered at 100% DPF load (as noted by others) and as displayed by the scangauge/torque Pro and are only related to the magic 300km number by coincidence. Playing in Bendethra last weekend, and after an automated burn completed just prior to leaving the tar, I had the DPF back to 80+% in just over 100km of playing. Did a manual burn at the park exit (back to 8%) and then drove as per normal the rest of the week. The next automated burn kicked in at 100% which was 440 from the last automated burn and 340 or so from the manual burn.
So:
1. The burns trigger at 100% not a km value (as noted by others on the forums)
2. ~300km of easy/mid load driving does equate to around 100% dpf load
3. Playing off road can fill the DPF in 100km or less - Towing into a headwind too maybe???
4. The manual regen does postpone the automated burn as we expected/hoped so we can mitigate the fire risk offroad by burning when WE choose!. Though I dont know why my first test of this didnt work as expected.
Question - now that we have a way to monitor the DPF% has anyone seen it get hot enough to do a passive regen whilst driving? I havent done a long stint at 110 (cough) since Dave and I cracked the % PID but to date I have not seen the DPF light up or decrease by itself - only in response to the 5th injector firing.
We're also hoping to being able to read the dpf clogged % and display that on the scangauge/torque app. The info is there (I've seen it) we're just not sure how easy it will be to get it out, decoded and displayed. DONE :-)
Apologies if this info has allready been covered.
Cheers
