Title: Passat 1.8t ATW, DBW- Help with ABS coding Post by: kg6dxn on July 06, 2013, 12:01:51 AM I put the entire drivetrain from a 2001 Passat into a 1973 Porsche 914. The swap included: Engine, Tranny, ECU, Dash Cluster and steering column.
I have eliminated all DTC's except the ABS module. The code is held in the ECU, transmitted over the gateway to the instrument cluster. The cluster displays "STOP, Owners Manual" with a "Ding" over and over. BTW, I don't have ABS brakes... Does anyone know how to turn the ABS off in the ECU? If anyone is curious, my build thread is here http://www.914world.com/bbs2/index.php?showtopic=187914 (http://www.914world.com/bbs2/index.php?showtopic=187914) Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: RaraK on July 06, 2013, 10:29:31 AM did you code the cluster to no ABS maybe?
Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: kg6dxn on July 06, 2013, 10:41:45 AM did you code the cluster to no ABS maybe? The ECU is holding the code, not the cluster. The cluster only displays it. VCDS shows no codes in the cluster. The ECU shows several ABS codes. I was able to code the SRS out of the cluster. Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: Carsinc on July 06, 2013, 07:02:12 PM A 01 is new enough to have esp or asr. That is why the ecu have faults the DBW is affected by traction control,
This is something I am also curious about? I wish I had answers for you but I do not as of now. I'm looking into the same kind of thing I put a r32 engine in a thottle cable 2.0 car so the car has abs but no asr. Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: BDK on July 06, 2013, 08:03:18 PM Did you recode gateway? (address word 19), it's part of the cluster. If I remember right you'll code it to 0 as its a standard trans, without abs and without airbag. I think that will take care of the warnings in the cluster.
Post the ecm part number I'll look at the coding chart for that as well, or use vcds which should give you coding charts for both.

If I remember right you'll code it to 0 as its a standard trans, without abs and without airbag. I think that will take care of the warnings in the cluster. The ECU is a 4B0 906 018 BG. Dazq tried to help me via remote Teamviewer. 034 Motorspot locked the ECU and it can't be read. I opened the case in hopes to ground pin 24, boot mode but they epoxied all over the eprom. I think I will do more damage trying to remove the epoxy.Post the ecm part number I'll look at the coding chart for that as well, or use vcds which should give you coding charts for both. Not sure what to do. I guess I need to take it back to 034 for an update. Any ideas? Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: kg6dxn on July 06, 2013, 09:19:03 PM I also took the car to the VW dealer. The service manager is a young kid that is into modified cars. He was stoked to help me but says his VAS device has less features than my VCDS and the factory does not support removing ABS. Apparently ABS is standard on all VW's around the world, so a ROW code will not help either.

Any ideas? JUST a guess, A different 95040 file may allow you the read/write the eprom. make sure to save a copy of the 95040 thats there or it may never work again Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: kg6dxn on July 06, 2013, 09:27:06 PM I thought unitronic were the only ones that epoxied the eprom, OK, but since I'm a newbie, I'm not sure what that means... ???JUST a guess, A different 95040 file may allow you the read/write the eprom. make sure to save a copy of the 95040 thats there or it may never work again Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: k0mpresd on July 06, 2013, 10:55:00 PM epoxy is nothing to be afraid of. not to mention, there are several locations for a bootpin on the ecu.
Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: Carsinc on July 06, 2013, 11:04:23 PM there are several locations for a bootpin on the ecu. This is a good point, I only use the one but have seen a video with atleast one other.Look into to this first. The 95040 is the immo chip, some tuners use it make their files a pain in the ass. Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: ddillenger on July 07, 2013, 03:30:59 AM You can use this pin on the RAM chip as a bootmode alternative. Follow the same protocol but substitute the pin shown for the eeprom pin 24. It's on the underside of the board.
(http://i795.photobucket.com/albums/yy231/k0mpresd/alt_bootpin.jpg) Thank k0mpresd for this one. Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: vwaudiguy on July 07, 2013, 06:44:12 AM K0mpresed stated there were "several" locations. Where are the other boot pin locations? What happens when they start dipping the whole circuit board in epoxy? j/k ;D

What happens when they start dipping the whole circuit board in epoxy? j/k ;D i see 2 pretty easy to use points in that picture up there. do you really need someone to tell you to just follow the trace? Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: ddillenger on July 07, 2013, 10:55:17 AM Get a DVOM and go to town. There are 3 that I use.
Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: kg6dxn on July 07, 2013, 11:11:01 AM Assuming boot mode is possible. How would one disable the ABS? I just need to disable the reporting over the gateway.
VCDS log shows this in the 01 Engine module Quote 17931 - Crash Signal from Airbag Controller P1523 - 35-00 - Implausible Signal 18057 - Powertrain Data Bus P1649 - 35-00 - Missing Message from ABS Controller Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: BDK on July 07, 2013, 03:15:37 PM Are you actually getting an abs light or just the brake warning light?
Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: kg6dxn on July 07, 2013, 03:38:55 PM Are you actually getting an abs light or just the brake warning light? Not sure about the actual light, I opened the cluster and painted the LED's black. But I believe they were on and that's why I painted them. In fact, I think both ABS and brake pad warning lamps were on.The warning is on the multifunction display. It says: "STOP, Service Manual" every time it does, the dash "Dings" an alarm. This message cycles over and over. I did open the cluster and de-solder the buzzer but the display cannot be cleared. The same display also reports outside air temp and fuel economy along with every other engine related problem. I can only see temp and economy for 2 seconds when the car first starts. If I can interrupt the ABS signal, the system will be fully functional. Normally the ABS reports status to the ECU. Since I don't have ABS, it is in constant alarm. Nobody I'm aware of can program out the alarm from the cluster and the cluster shows no codes. Here is the entire scan... BTW, the air bag code only lights up the lamp and does not effect driveability.

Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: Carsinc on July 07, 2013, 08:19:39 PM Thats the best offer you could ever hope for.

If you still get a warning, more investigation will be needed. Awesome! It will take me a few days to get back to you. I don't want to post the file openly since it is 034's proprietary tune. Now is it as simple as grounding the pin? 1) disconnect battery 2) ground pin 3) turn key on 4) Connect battery 5) remove ground at pin 6) read flash Is that it? Do I use the NefMoto or do I need a third party program to read from boot? Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: Carsinc on July 07, 2013, 08:33:22 PM I use a galletto 1260 clone off ebay, I was told they suck MPPS will do the same I'm told their better ;)

I just need to disable the reporting over the gateway. VCDS log shows this in the 01 Engine module I too am intrigued about removing these from ME7.5 WB converted cars. They have no bearing on adaptions but scare the customers seeing it because they expect a clean code read. The issue is this, The cars are early ME7.1's and the component parts won't support these missing parts being wired in. Should i convert the P code to hex and dig further through the hex? TIA Title: Re: Passat 1.8t ATW, DBW- Help with ABS coding Post by: nicktruman on April 22, 2020, 09:44:39 AM Hi, Did this ever work? I too have no ABS and the cluster isn't happy, i get a STOP Brake fault Service Manual message on the multi function display, the buzzer has long gone!
I coded ABS out of the CAN gateway but message wont go. VW 20v 1.8T AWT me7.5 ecu and immo3 dash from 2002 Passat Any ideas? I've been through Ross Tech's stuff.. and cant find anything, is there a way to trick the ecu that the ABS is fine? I have a dump of the dash if that helps anyone please.
