Title: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: davgeek on August 19, 2019, 04:57:54 PM I made a 1.8T swap on my Ibiza, but it doesnt have a physical signal for ecu, thanks!

Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: _nameless on April 11, 2020, 04:58:33 PM post your original file and i can swap it for you. i can find the bit to swap but i cant recall the name of it
Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 11, 2020, 05:53:27 PM canbus I made an test a few minutes ago. I unpluged the speed sensor harness on gearbox, and took a ride. No VS on cluster (expected), no VS on ECU (expected) and no VS on Climatronic too (channel 17 of diagnosis). If climatronic sources VS from canbus, it should keep displaying VS. If my logic is right... Another test I did, was set CWGGVFZG = 1 on the ECU, but no VS on ECU either. What I can think is my ABS module is not connected to my car CAN or my car dont have CAN at all. Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 11, 2020, 06:21:14 PM I just looked on eletrics schematics of my car on ElsaWin, and there is dedicated wire from cluster to climatronic for VS.
T32 (blue connector) pin 31 (speedometer output 2) on cluster to pin C8 on climatronic.

T32 (blue connector) pin 31 (speedometer output 2) on cluster to pin C8 on climatronic. Swap bite 65 from 80 to 81 thatshould pickup speed from can for the cluster. Bit in ecu needs to go from 0 to 2 and thats speed from can on both Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 12, 2020, 09:21:40 AM Swap bite 65 from 80 to 81 thatshould pickup speed from can for the cluster. Bit in ecu needs to go from 0 to 2 and thats speed from can on both Byte 65 on my cluster is 48. This trick of changing from 80 to 81 is only valid to MK4 GTI clusters. The A3 8L cluster is different :(. My cluster EEPROM is attached. Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: macxxx on April 12, 2020, 10:44:25 PM You can't change that in an a3 8l cluster - the only way to workaround is to connect analog speed signal from abs ( dedicated to navigation system if its mounted in the car ) to cluster in tbe place of the speed signal from gearbox

Do you know which PIN is this on the ABS module connector? Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: macxxx on April 13, 2020, 04:33:54 AM It depens what year and number of abs controller - i can check it in diagrams
Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 13, 2020, 04:39:07 AM It depens what year and number of abs controller - i can check it in diagrams Here in Brazil the 8L A3 was sold until 2006. My car is 2004. Its an ME7.5 narrowband (512kb), no VVT, engine code APP. The car has only ASR, no ESP. ABS unit is MK60. You said that the ABS module has an analog speed signal output. Do you have more details about this signal? 0-12v? From what I know, the gearbox speed sensor outputs to the cluster an "digital" signal. It pulses 7 times for every wheel rotation. So its like an square wave. Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: macxxx on April 13, 2020, 05:03:17 AM Its the same signal , I used it in a4 b5 or a6 c5 after gearbox swap witout a speed signal sender
Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 13, 2020, 05:45:36 AM Its the same signal , I used it in a4 b5 or a6 c5 after gearbox swap witout a speed signal sender I found some schematics of the MK60 abs unit. Based on the information you provided, I found this 2 relevant pins: T47/8 => Vehicles with navigation system only T47/10 => Vehicles with navigation system only These two pins must be signal and ground of the speed output right? Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: macxxx on April 13, 2020, 06:49:57 AM No , use one of them - its left rear wheel and left rear wheel ( look at rnsd pinout 26 pin connector )
Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 13, 2020, 07:33:44 AM No use one of them - its left rear wheel and left rear wheel ( look at rnsd pinout 26 pin connector ) I looked this RNS-D 26pin connector diagram. It goes to these pins I mentioned (8 and 10). I attached the diagram of this part. J104 is the ABS module, J503 is the navigation system. Wires goes from ABS T47 8 and 10 to RNS-D T26 5 and 18. This is right? Worth a test? Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: macxxx on April 13, 2020, 07:55:33 AM Yes it should work - connect it to cluster in the place of speed signal from gearbox
Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 13, 2020, 10:17:25 AM I will try this next weekend. I will report back here.
My need for this is because I bought an 02Q gearbox, that dont has an VS sensor. Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 19, 2020, 05:37:38 PM Yes it should work - connect it to cluster in the place of speed signal from gearbox I just wired two wires on that pins (8 and 10) on ABS module, hooked up my portable osciloscope, but no signal on either pins (together or relative to ground). I think I need to change the ABS module coding, to enable this pins output. I guess. Will try soon. Any help is valid. Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: aef on April 20, 2020, 02:42:31 AM I know someone with arduino/can box in S3 8L DQ250
This will read out Speed from ABS via CAN and send it to the Cluster. You can finetune it too. regards Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on April 20, 2020, 04:55:30 AM I know someone with arduino/can box in S3 8L DQ250 This will read out Speed from ABS via CAN and send it to the Cluster.

I'm reading the CAN messages here, with Arduino. But I'm having trouble decoding the messages.This will read out Speed from ABS via CAN and send it to the Cluster.

What you use to reqd CAN?
Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: dal on May 04, 2020, 03:58:24 AM What mesage you have trouble with? What you use to reqd CAN? I'm using a simple Arduino Nano + MCP2515 setup. Connected to the car CAN, and reading with 125kbps. I'm trying to get any data from the messages, but my target is to get VS. Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: BlackT on May 04, 2020, 06:30:46 AM Do you have any filter for mesages?
You can start with RPM, it is at 0x280, LoHi 4,5 byte. I will check this later to confirm. RPM is easy one to stsrt with beacuse you don't need to move car Title: Re: Its possible to take A/C signal from climatronic on me7.5 like get VSS from ABS Post by: fknbrkn on May 04, 2020, 06:43:33 AM Also it's running on a 1mbit
