Diagnostic Trouble Code (DTC) Identification

NOTE: Some Diagnostic Trouble Codes (DTCs) have more than one meaning. Malfunction Indicator Light (MIL) is unable to distinguish between different failures. As an example, there are 4 different failures possible for the oxygen sensor (O2S) system, MIL can only identify an O2S failure by flashing a DTC 21. MIL is capable of displaying all possible system failures.
NOTE: A scan tool may not be able to identify all possible Diagnostic Trouble Codes (DTCs). As an example, a scan tool may not be able to identify or display a DTC for a malfunctioning A/C clutch relay circuit. There are 21 DTCs which a scan tool cannot identify. The Malfunction Indicator Light (MIL) must be used to identify these malfunctions.
