Diagnostic Mode 07 - Read Faults Detected During The Current Or Last Driving Cycle
Mode 07 makes it possible to check emissions-related faults which appeared during the current or last driving cycle (pending DTCs).
A pending DTC is saved the first time a fault is detected (output via Mode 07).
-- If the fault is detected again by the end of the following driving cycle, a confirmed DTC is entered (output via Mode 03) and the MIL is activated.
-- If this malfunction is not detected again by the end of the following driving cycle, the corresponding pending code will be deleted at the end of the driving cycle.
Depending on scan tool and protocol used, some of the information provided may be referred to by a different name.
