Re: [opendiag] Re: Keyword 0808

hi Ezequiel

1.) VW use the protocol KWP1281 ( nothing to do with KWp2000 ). But if an VW ECU responds to fonctional ECU Add. 0x33 ( e.g passat 1999 ) you can communicate with ISO9141-2 too.

2.) KWP2000 ( after ISO14230 ) must use the keywords 0x8f and 0xE9 or ( 0xex manufacturer specifique ) also only ISO 9141-2 use the keywords 0808 or 9494
 
3.) this command sequence that i described is figured in ISO9141-2 page 14.

4.) we have tested this car too with our mOByDic chip . it runs only with ISO9141-2

best regards

Bülent

Sorry but you are not reight. That command sequence corresponse to
ISO 14230 (also known as KWP2000 for VW) and not to ISO 9141 (also
known as KWP1281 or 1271 for VW).
