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? Title: Re: Code out Airbag and ABS Post by: Tshirt2k on October 07, 2014, 06:50:28 AM Might be worth looking here.

Title: Re: Code out Airbag and ABS Post by: Tshirt2k on October 08, 2014, 03:26:38 PM If you read funktionsrahmen. I think you can use cw_can_r.
Title: Re: Code out Airbag and ABS Post by: ddillenger on October 08, 2014, 05:55:16 PM 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.
Title: Re: Code out Airbag and ABS Post by: Tshirt2k on October 09, 2014, 01:35:30 AM 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?
Title: Re: Code out Airbag and ABS Post by: carsey on October 09, 2014, 06:18:08 AM 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
Title: Re: Code out Airbag and ABS Post by: ddillenger on October 09, 2014, 01:19:56 PM 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. Title: Re: Code out Airbag and ABS Post by: tjwasiak on June 15, 2015, 01:20:15 PM 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.
Title: Re: Code out Airbag and ABS Post by: ddillenger on June 15, 2015, 01:24:41 PM CWCS
lol Title: Re: Code out Airbag and ABS Post by: tjwasiak on June 15, 2015, 01:56:45 PM 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. Title: Re: Code out Airbag and ABS Post by: BlackT on February 18, 2019, 12:50:18 PM 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 Title: Re: Code out Airbag and ABS Post by: BlackT on February 26, 2019, 12:04:57 PM Anybody? Does anybody can give me some trace, where to start searching?
Title: Re: Code out Airbag and ABS Post by: BlackT on March 04, 2019, 01:12:30 AM 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 Title: Re: Code out Airbag and ABS Post by: BlackT on March 04, 2019, 12:32:48 PM 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 ??? Title: Re: Code out Airbag and ABS Post by: paddy26 on April 28, 2021, 02:05:05 AM 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? Title: Re: Code out Airbag and ABS Post by: stuydub on April 28, 2021, 03:11:19 AM 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 ? Title: Re: Code out Airbag and ABS Post by: paddy26 on April 28, 2021, 04:07:47 AM 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 Title: Re: Code out Airbag and ABS Post by: paddy26 on April 28, 2021, 08:15:23 AM Thanks
Title: Re: Code out Airbag and ABS Post by: paddy26 on April 28, 2021, 02:26:31 PM 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. |
