Different from xtool AD10 and EM327, XTOOL AD20 obd 2 diagnostic 2025 does not only provide full obd2 functions, but also an in-depth inspection of the engine system. With the capability of retrieving the MIL trouble code, once the car issue has been repaired or resolved, the AD20 bluetooth obd2 scanner can be used to clear the error codes and reset the MIL.
