July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Diagnostic Trouble Codes (DTCS)

A diagnostic trouble code (DTC) is stored if the control module detects a fault.

This control module can store up to six diagnostic trouble codes (DTCs), the three first and the three latest.

Should a fault disappear for any reason after being permanently stored in the control module as a diagnostic trouble code (DTC), the information remains stored in the control module.
