ran the diagnostic tool - got the results for everything ok

for Fuel System Monitor - It is showing INC.
I used Autel MS-309
I couldn't get any "P" codes.

Anyone got any idea?

thanks

found this from the manual -

A number of factors, including erasing of diagnostic trouble codes (DTCs) with a code reader or a disconnected battery, can result in Readiness Monitors being set to “INC” (incomplete). Since the three continuous monitors are constantly evaluating, they will be reported as “OK” all of the time. As long as there are no DTCs stored in memory, the vehicle is running in accordance with the OBD II guidelines. If testing of a particular supported noncontinuous monitor has not been completed or not tested, the monitor status will be reported as “INC” (incomplete)

“INC” -- Indicates that the testing of a particular monitor being tested is incomplete. Additional driving is needed
