Title: KWP2000, VAG Cars Post by: brateq on March 02, 2016, 05:45:54 PM Hi all, at first sorry for my English i will try my best.
I've got a little problem to understand how KWP2000 in VAG cars is working. I'm trying to get measuring blocks on Elm327. In TP2.0 ( KWP2000 over the CAN ) it's working perfect however, in KWP2000 i must set receiving ECU in header and here is my question. Is there any possibility to set header or any other method to use logical VAG addresses ( 0x01 Engine, 0x03 ABS, 0x17 Instruments etc. ) After i read a lot of informations i can't figure it out for VAG cars... After sniff VCDS when connecting to Instruments ( 0x17 ), data request from vcds looks like this: 81 61 F1 1A 92 CHECKSUM This indicates that instruments ( vag logic 0x17 ) ECU physical address is 61. This physical address is same for every vag car? Also i found opensource logger for KWP2000 and here are instructions for ELM327 to get transmission oil temp AT IIA 26 <-- ( 26 physical address for transmission ecu? ) AT SH 80 02 F1 <-- ( VAG logic 02 for transmission ) I'm really confused... Thanks for any help Title: Re: KWP2000, VAG Cars Post by: dope40 on July 14, 2017, 04:01:30 PM Hi,
Here is a great explanation on the topic. https://www.blafusel.de/obd/vag_kw2000.html Title: Re: KWP2000, VAG Cars Post by: superglitch on July 14, 2017, 09:20:42 PM Found on github some time ago related to VAG cars.
