Connect the scan tool to the vehicle’s DLC and erase the DTC(s) 
from the vehicle’s computer memory. (

See

 4.2 Erasing Codes

2)

 

After the erase procedure is performed, status of most monitors 
will  be  changed.  Leave  the  scan  tool  connected  to  the  vehicle, 
and select 

Ready Test

 from 

Main Screen.

 

3)

 

Keep on driving the car till the scan tool notifies you safely with 
color  LEDs  and  audible  tone  that  the  drive  cycle  has  been 
completed  and  the  vehicle  is  ready,  eliminating  drive  cycle 
guesswork and confirming readiness status. 

4)

 

If  the  GREEN  LED  lights  and  two  long  beeps  are  heard,  your 
vehicle is ready and the repair work is confirmed. 

5)

 

If the RED LED lights, your vehicle is not ready and the repair 
work is unsuccessful. 

As Pre-Check Diagnostic Tool 

Prior to having a vehicle inspected for compliance to a state emission 
test, you could use this function to check the readiness status first by 
yourself. 

1)

 

While the scan tool connected to the vehicle, select 

Ready Test

 

from 

Main Screen

. Drive the car till the scan tool notifies you 

safely with color LEDs and audible tone if your vehicle is ready 
to conduct state emission test. 

2)

 

If  the  GREEN  LED  lights  and  two  long  beeps  are  heard,  your 
vehicle  is  ready  and  there  is  a  good  possibility  that  it  can  be 
certified. 

3)

 

If  the

 

RED  LED  lights,  your  vehicle  is  not  ready  and  must  be 

repaired before an emission test can be performed.
