Use and Care Manual

As pre-check diagnostic tool:
Prior to having a vehicle inspected for compliance to a
state Emissions Test, you can use this function to check
the readiness status of the DTCs first by yourself.
1. With the Scan Tool connected to the vehicle, select
Ready Test from the Main Screen (See Figure
3.1). Drive the car until the Scan Tool notifies
you with the LED (and tone, if enabled).
2. If the GREEN LED displays and two long beeps are
heard, there are no stored and pending DTCs that will
cause a problem during an Emissions Test at this time.
3. If the RED LED displays, your vehicle is
not ready for an Emissions Test.
WARNING!:
If you are driving the vehicle to perform a
drive cycle ALONE, please set the Status Beep On
(See 3.8 System Setup). By listening to the beep,
you will learn when the monitors have run and
completed the diagnostic testing. NEVER try to
drive and operate the Scan Tool at the same time!
NOTE:
This function reads off the real time data of emission-
related monitoring systems readiness status. Once
the Scan Tool has finished other operations, for
example, clearing trouble codes, the I/M Readiness
Monitor Status program resets status of all the
monitors to “INC” condition. In order to set these
monitors to a "Ready" status, the vehicle must be
driven through a complete drive cycle. Times for
reset vary depending on vehicle. Please refer to your
vehicle’s service manual for drive cycle information.
NOTE:
In this function, only the ESC button is available. The
other buttons are disabled to prevent misoperation.
