ECU scanning on 2004 Grand Caravan
 

Working on a project to find ELm327 SW that reads extended codes of
a 2004 Grand Caravan, and have a few issues:
- Which ECu resides in a 2004 Gran Caravan, NGC?
- Anyone knowing opensource that reads extend codes (ABS especially)
- Anyone knowing command syntax for reading extended/ABS codes maunally over RS232?

Try the Snapon code reader, it coist £1,100 but is great
