Subaru Specific Fault Codes

Here's a list of the fault-codes that correspond the 'Check Engine' flashes from the 'Black-Socket Trick'. The number of long flashes represent the first digit of the code and the short flashes are the second digit, i.e 2 long flashes and 3 short would be a code 23.

[If you have a plug-in module for reading OBDII fault-codes then you'll need this set of codes instead - generic Subaru OBDII trouble code definitions - from ScoobyPedia.]
