CaddyDaddy Posted June 9, 2004 Report Share Posted June 9, 2004 I have an '89 SeVille and was looking through the OBD and found a BCM override that was "129 option 1" and "0 option 2" does anyone know what these options are?? Is there someway to set the option to be able to moniter another system while not in diagnostics mode??? I have a Chiltons manually that tells everything about the OBD system and what everthing means exept for these two. Can anyone help explain what this Option 1 and Option 2 is all about?? Thanks Link to comment Share on other sites More sharing options...
