How to clear the fault codes on your Subaru including Legacys and ImprezasMost cars simply store fault codes and thats it. Subarus on the other hand have 2 modes. You can read the stored fault codes or you can check them while the car is driven. This is useful if you have a fault code that only appears when you drive and doesn't hang about long enough to be stored.Reading and clearing the codes themselves is pretty easy. This method should work on all Pre 1999 Subarus with proper ECUs (so if you have a 1978 Brat pick up you don't need to read any more!) After 1999 Subaru began using the EOBD system on their UK cars. I am not 100% sure if the imports after 1999 can still be read like this. No harm in trying I suppose!How to read the stored codes. Do this before you try the dynamic method.Turn the ignition offFind the diagnostic connectors. They are usually under the dash on the drivers side near the centre console. There should be a pair of black connectors (1), a pair of green (2)and a big yellow one (3 We don't need to worry about that!). You are looking for the black pair.Connect the black connectors together.Turn the ignition on but don't start it.Check the engine management light comes on. If it doesn't some snake in the grass has disconnected it! This happens because people are scared of having to take the car to the dealer to have it fixed!Count the number of flashes. Long flashes count for 10 and short ones are single units. So the code 38 would be 3 long flashes then 8 quick ones.If it just flashes long flashes continually there are no codes stored.Anyway, count the flashes and check against the list below.Turn the ignition back off then disconnect the black connectors. If you mess things up just disconnect the black connectors and start again.Fault codes1111
