Important: Not all vehicles will have every diagnostic trouble code (DTC) listed in each section. For example, a vehicle may have only 2 oxygen sensors or 1 catalyst. Only those DTCs applicable to the vehicle are required to update each System Status to YES. Refer to the appropriate service manual to determine which DTCs are supported for each vehicle.
