The purpose of this function is to indicate which of the vehicle‟s
monitors have run and completed their diagnosis and testing, and
which ones have not yet run and completed testing and diagnosis of
their designated sections of the vehicle‟s emission system. All data
shows on one screen, which provides a simple profile of vehicle at a
glance, saving diagnosis time and improving technician productivity.
Use the UP/DOWN scroll button and LEFT/RIGHT scroll
button to select Ready Test from Main Screen (Figure 6.1),
and press the OK button.

As post-repair diagnostic tool
This function can be used (after the vehicle has undergone
any emission-related repairs) to confirm that the repair has been
performed successfully.
After repairs, some drive cycles are required to reset the monitoring
systems. Drive cycles vary between vehicles and for each monitor in
any particular vehicle.
Use the following procedure to check if the repair has been done
correctly:
1) Connect the scan tool to the vehicle‟s DLC and erase the DTC(s)
from the vehicle‟s computer memory. (see 5.2 erasing codes)
