How do I verify whether my vehicle is ready to pass the emission test?

There are three LED indicators on the code reader. Green LED indicates your vehicle is in good condition. Yellow LED indicates there are some issues waiting to be fixed and clear codes. Red Led indicates your vehicle serious problem, you may not pass the emission test if these problems could not be fixed.

Where should the code scanner insert to?

The OBD2 port is often under the dash, or under a panel below the handbrake in the center console.

Why I can’t erase the fault code?

The fault causing the fault code to show will need to be repaired first then code can be erased.
