Someone was asking the other week how to clear fault codes and it was suggested that you could disconnect battery for a couple of hours.
Heres an easier way - Bridge the diagnostic connector terminals 1 & 8 as you normally would to read fault codes. After you have read the codes, leave the ignition on and reconnect the jumper between 1 & 8 again for two seconds or more & then remove it again - fault codes cleared. You should now only display 0505 code. This is a diagnostic validation code - it is displayed to let you know that diagnostics is working but there are no codes stored.
