Thank you very much cintakc

How can I know what each one corresponds to?

Mainly I want to know the km since the last regeneration and the % saturation of the filter

PIDs for DPF Mokka
2220F2, 2220F4, 2220F5, 2220F6, 22131F

I have verified that the 5 PIDs give me an answer but I don’t know how to configure them

put here what answers the ECU gives on these PIDs, I’ll look at formulas

The values are read in Hader 7E0

The values of A and B in HEX

2220F2
Response 6220F200 A= 00 B= -1

2220F4
Response 6220F400 A= 00 B= -1

2220F5
Response 6220F509 A= 09 B= -1

2220F6
Response 6220F601 A= 01 B= -1

22131F
Response 62131F0000 A= 00 B= 0

Cintakc, on z17dtr, using aa0318 gives me the same response…a,b,c and e, same values as many other pids I try.
A is soot, E is number of succesfull nr of regen, and C maybe diff pressure…

Example of responses, (hard to get on “Test” mode), most of them i can get only in dashboard, not in pid lists (all remain black there…)

result of equation:41.34
start diagnostic response:
OK
OK
OK

Command:
aa0329

Response
5E8829351706013B0000
5E8829351706013B0000
5E8829351706013B0000
5E8829351706013B0000
5E8829351706013B0000
5E88293517351606013B0000
5E8829351706013B0000

OR, (with 1 hz refresh rate), the line 6 became shorter:
5E882935166013B0000

I think i get same answers for many pids due to atcra start and stop commands, without them i get NO DATA. with start command “20” i get no data

Do you have pids for dpf (or cat) temperature, ash level, oil dillution?

Thank you!

response 41,34 was a*0.78, so “A” was 53…

2220F7		A*256+B			km
Average DPF Inlet Temperature During Regeneration
2220F8		(A*256+B)*0.1-40	        degree C
Average DPF Regeneration Duration
2220F9		A*8			S
Calculated DPF Flow
2220F5		A*0.01			Kpa
Distance Since Last DPF
223039		A*256+B			km
DPF Differential Pressure
2220F4		Signed(A)		Kpa
DPF Regeneration
2220F6		Lookup(A::0='Not required':1='Required')
DPF Regeneration Status

First of all, thank you very much cintakc for your quick answers.

Below I attach the results of the test that you requested. I have not configured Header or min and max values.

I would also miss the PID of DPF Soot Accumulation

Average Distance Between DPF Regenerations
2220F7 A*256+B km
Result for equation: 1045.0 Response= 6220F70415 A=4 B=21

Average DPF Inlet Temperature During Regeneration
2220F8 (A*256+B)*0.1-40 degree C
Result for equation: 625.8 Response= 6220F81A02 A=26 B=2

Average DPF Regeneration Duration
2220F9 A*8 S
Result for equation: 448.0 Response= 6220F938 A=56

Calculated DPF Flow
2220F5 A*0.01 Kpa
Result for equation: 0.09 Response= 6220F509 A=9

Distance Since Last DPF
223039 A*256+B km
Result for equation: 1120.0 Response= 6230390460 A=4 B=96

DPF Differential Pressure
2220F4 Signed(A) Kpa
Result for equation: 0.0 Response= 6220F 400 A=0

DPF Regeneration
2220F6 Lookup(A::0=’Not required’:1=’Required’)
Result for equation: 1.0 Response= 6220F601 A=1

DPF Regeneration Status
2220F2 Lookup(A::0=’Not required’:1=’Stage 1′:2=’Stage 2′:3=’Stage 3′:4=’Stage 4′)
Result for equation: 0.0 Response= 6220F200 A=0

DPF Differential Pressure Sensor
222035 A*5.0/255 Volt
Result for equation: 5.0 Response= 622035FF A=255

castas,
and how do you think the values are real?
are the values with the engine running?

Response= 6220F70415 A=4 B=21

do not need to paint A = B =
just write the answer Response= 6220F70415

Re: Vauxhall (Opel GM) DPF PID

I have understood the Values A and B.

The tests have been made with the engine running

Regarding the values, I believe that the last regeneration made it less than 1000Km ago.

However the PID 22039 with the equation A * 256 + B I have it configured a week ago and has been increasing from 720 km without any regeneration has occurred since then

However, if I had the% of accumulation I could know, more or less, how much is missing for the next regeneration

The Average DPF Regeneration Duration I think it’s fine.
Whenever I see that the car made a regeneration when I returned from work I made the same route at 80Km / h in 3rd gear and lasted about 7 or 8 minutes

As much as I search and research, I can not find the PID to know the saturation percentage of the DPF in Opel 1.7 engines

First, thanks for your quick response

I have made a 30 km route to see if this change the response about pid 1a90 and 1a9a and there have been no changes

these are PIDs for auto identification and ECU engine block
I need them for the scanner

Re: Vauxhall (Opel GM) DPF PID

I looked exactly on your engine, there are more than 200 parameters, but the parameter percentage of saturation DPF in engines Opel 1.7 – no
this is all that is, maybe this gradation is 4 steps, there is 100% divided by 4
DPF Regeneration Status
2220F2 Lookup(A::0=’Not required’:1=’Stage 1′:2=’Stage 2′:3=’Stage 3′:4=’Stage 4′)
incidentally, here are a few more PIDs

Fuel volume in tank
22132A		(A*256+B)*0.015625			L	
Desired boost pressure
22328A		(A*256+B)*0.01				kPa
Fuel rail pressure request
22308A		(A*256+B)*0.01				MPa

Okay. I will test this afternoon and indicate the result.

With the time that it made the last regeneration it should be in 3 or 4

I can not get it to do a regeneration in order to control it.

Today I made about 250 km. The PID 223039 already marks 1470 km since last regeneration

The PID 2220F2 always marks ‘Not required’
