Fault Codes: Notes

Fault codes (or trouble codes) are 2 digit numbers that identify which circuit is bad. In most cases the fault codes do not identify which component is bad. Therefore, a fault code is only the result, not the reason for the problem. There are some cases in which the fault code is the reason for the problem. It is important that the test procedure be followed in order to fully understand the possible cause of the fault code.
