Can it support the Mode-6 On-Board monitor test ?
-Yes, You can judge whether there is a problem in the car through the maximum and minimum values when you using this YA301 Code Reader. (Mode-6 depends on whether the car's ECU can support)

Can it support Mode-8 EVAP/ Component Test?
-Yes, You can know the accurate fuel ratio and improve the performance of the car using this YA301 OBD2 Scanner.

Can it read the hidden Codes, if my car does not show up DTCs?
-Yes, for the engine, it can read the hidden codes with the data stream functions; For the battery, it can get an early warning via the battery voltage test function using the YA301 Code reader vehicle diagnostic tool

Does it read and clear Airbag, SRS and ABS etc. errors?
-No, this device only read and clear Engine errors.

But my car has the 16-pin OBD connector, shouldn't it be OBD-II compliant?
-No, not necessarily. A lot of European and Asian manufacturers equipped their vehicles with D-shaped 16-pin connectors long before they began installing OBD-II systems on those vehicles. One curious thing to note here is the fact that most non-EOBD compliant vehicles had a DLC that does not fully conform.
