Searching the OBD command to initiate a DPF regeneration

Fri Apr 12, 2019 4:31 pm

Hi,

Need the community help to solve this long lasting mystery I just cant resolve.

I am trying to find the right code to send through my ODB dongle, so I can trigger a DPF regeneration my self. Without the need for a mechanics.
Pajero, 2008, Diesel, 7 seats.

Background:
When I get the DPF light on, sometimes I just cant make it in time to clear it by driving.
Then the light starts flashing and the check engine turns on.
At this point I have to go to the mechanics for a computerized triggered DPF regeneration.

The mechanics then just clicks on his OBD computer and triggers the Regeneration.
It takes about an hour of still standing, engine on, high RPM, and the DPF is cleared.
You can see the system he is using here :

1. This is the tool the mechanics use -
2. The KPI I am monitoring is "Soot loading by summation" -
3. And the KPI value over time is here (60 minutes) -

Any idea ?

-- I found the instructions for Toyota, but it doesnt help. (see here - http://forum.canb.us/topic/105/obd-ii-c ... response/2)

Thanks
Gur

Just remove the DPF from the exhaust. It’s about an hour DIY job.
