Actron 9640 User Manual

Vehicles may support two types of I/M Readiness:

❒

SINCE DTCs CLEARED shows monitor status since DTCs were erased. 

❒

THIS DRIVING CYCLE shows monitor status since current drive cycle 

started. 

If monitors are not supported for THIS DRIVING CYCLE, Scan Tool only shows 

monitors for SINCE DTCs CLEARED with no header on line 1.

Select I/M Readiness from OBDII 

Function List menu and press 

ENTER. 

Scan Tool displays message stating whether or not I/M Readiness monitors are 

completed.

Use 

DOWN arrow key to view monitor statuses. If both monitor types are 

supported, use 

LEFT/RIGHT arrow keys to toggle between monitor types. 

• A status of “OK” means required driving conditions for that monitor have 

been met and monitor has ran to completion.

• A status of “Inc” means required driving conditions for that monitor have 

not been met or monitor did not complete its cycle.

• A status of “N/A” means vehicle does not support that monitor. 

When done, press 

BACK key to return to OBDII Function List.
