yeah i know i kinda guessed they were manufacturer specific, but i was hoping the scan tool would bring up any faults that may be present, or perhaps the codes were just a manufacturer-specific mask for the real code....
the annoying thing is, i cant remove them

tried disconnecting the battery and removing the ECU related fuses etc... no good. unless they are still active.
Another one popped up the other day!
my car has an obdii port with pins 2, 4, 5, 7, 10 and 16 populated.
Thanks
