Title: Code out Airbag and ABS
Post by: turboat on October 07, 2014, 05:22:57 AM
Ive got a AUQ 1.8T 032HN thats been chopped into another vehicle, sorted out most of the fault codes, but Im stuck with these in the Engine ECU:

2 Faults Found:
17931 - Crash Signal from Airbag Controller
            P1523 - 35-00 - Implausible Signal
18057 - Powertrain Data Bus
            P1649 - 35-00 - Missing Message from ABS Controller


The cause of the issue is obvious, I dont have ABS or Airbags, but it would be nice to code these out, the current softcoding is 11510 - I cant find a coding table for this ecu, before I trial and error, does anyone have any info on this?

Might be worth looking here.

Cheers, thats certainly an option, but I would prefer to code them out, rather than editing the error classes so they dont get thrown.

If you read funktionsrahmen. I think you can use cw_can_r.

CW_CAN_R is useful for the missing message, but the other one, I'm not sure about. You can certainly error class it, but there is likely a better way.

Regarding CW_CAN_R There are more words R_1, R_2 etc. On the file I was looking at (06A906032HN 0002)they all had the same data in 0x00AC which I have worked out what it means. But there was nothing to say what each of the other locations do. Do they all do the same thing?

I get these aswell.   Would be nice to find a way to get rid of them.   Got them coded out from the cluster via the CAN module

The additional variants are just that.

For variant coding.

You can see which one is used for which coding scheme if you look at the bits and how they're set.

Any other solution for 17931 DTC? I am sure I located all CW_CAN_R variants correctly as 18057 is gone - all 4 changed from 0x00AC to 0x0020.

CWCS

lol

Found it already but thanks for the answer.
If I understand correctly funktionsrahmen we should not clear airbag related CW_CAN_R bit if CWCS is set to 4 or 8.

Please i need help to code out cluster,ABS and airbag.
On 2.7T ECU 4B0 907 551 M i do it with no problem, i compare hex to M-box. Find the CW_CAN_R, set it to zero and it is working.
But i canon't find CW_CAN_R on my 1.8T ECU  :-\
SoftCod:11001

I will appreciate any help, I read all topic that search can provide, but still i can't get it how to find CW_CAN_R in 1.8T ECU

Anybody? Does anybody can give me some trace, where to start searching?

 4B0 906 018 CG
Comparing to some others bin, I think I located CW_CAN_R at
0x136E4     Hex:0x28
0x136E6     Hex:0x3C
0x136E8     Hex:0x28
0x136EA     Hex:0x3C

CW_CAN_C   
0x1019D    Hex:0x05

set all this values to 0x20
But didn't make any difference, stil got

18014 - Rough Road/Engine Torque Signal from ABS
            P1606 - 35-00 - Electrical Malfunction
17931 - Crash Signal from Airbag Controller
            P1523 - 35-00 - Implausible Signal
18058 - Powertrain Data Bus
            P1650 - 35-00 - Missing Message from Instrument Cluster

Okey I think my CW_CAN_R is located good.  When I set values to 0x00 i get rid off this DTC

18058 - Powertrain Data Bus
            P1650 - 35-00 - Missing Message from Instrument Cluster


Obviously on ME7.5   P1606  P1523 are not connected to CW_CAN_R, so I need to dig further.
To explain others, this how CW_CAN_R looks like.  In my case i need byte 5 set to zero so  0x3C set to 0x1C, and 0x28 to 0x08




Edit: only when I set CW_CAN_R to 0x00 i dont have cluster DTC.  I set i to 0x20 have cluster DTC, set it to 0x1C/0x08 again have cluster DTC. What doesen't have any sense  ???

I am having this same issue with coding out the instrument cluster. Mine is also a 1.8t(032hn) conversion into another car.
Did you chose to set CW_CAN_R to 0 or did you go with another solution?

what cluster are u running ?

Original cluster from my car(corrado).


Title: Re: Code out Airbag and ABS
Post by: BlackT on April 28, 2021, 08:07:09 AM
CW_CAN_R=0 
CWCS=0

Thanks

Just to follow up, as advised I changed
CW_CAN_R=0
CWCS=0

and the 18058 error code is now gone.

Thanks again BlackT.
