NOTE:
A generic OBDII Scantool can be used in place of the Toyota Diagnostic Tester.
CAUTION:
Strict observance of posted speed limits, traffic laws and road conditions are
required when performing these drive patterns.
NOTE:
These drive patterns represent the fastest method to satisfy all necessary
conditions which allow the specific Readiness Monitor to complete.
In the event that the drive pattern must be interrupted (possibly due to traffic
conditions or other factors) the drive pattern can be resumed and, in most cases,
the Readiness Monitor will still set to ªcomplete.º
To ensure rapid completion of Readiness Monitors, avoid sudden changes in
vehicle load and speed (driving up and down hills and/or sudden acceleration).
