Retrieving DTCS: Notes
NOTE:
It will be necessary to use MIL or digital odometer (if equipped) and scan tool to retrieve all DTCs. When using MIL or digital odometer to retrieve DTCs, some DTCs have more than one meaning. MIL or digital odometer is unable to distinguish between different failures for a specified component. For example, there are several possible failures for the oxygen sensor system, but the MIL or digital odometer can only identify an oxygen sensor failure by displaying a DTC 21. Scan tool is able to distinguish between different failures. When using a scan tool, scan tool is not able to identify all possible DTCs. As an example, scan tool may not be able to identify or display a DTC for a malfunctioning A/C clutch relay circuit, Auto Shutdown (ASD) relay circuit, or charging system voltage circuit, but these DTCs will be displayed by MIL or digital odometer.
