Subaru Error Codes PDF
What are you talking about?
In Subaru, self-diagnosis systems OBD-I and OBD-II are used. The purpose of these systems is unified definition of faults in various units and units of the car for making a decision on the subsequent repair.
The procedure for reading OBD-I codes is similar to Morse code: short pulses (0.2 seconds long) - units, long (1.2 seconds) - dozens. Pauses between pulses within one code are 0.3 seconds, and the codes (if there are several of them) are separated by long pauses in 1.8 seconds. OBD-I diagnostic codes are two-digit (they are also called "short", in contrast to the "long", five-digit extended diagnostic OBD-II codes).
