Toyota Corolla Repair Manual: Purpose of the readiness tests

Caution

: strict observance of posted speed limits, traffic laws, and road conditions are required when performing these drive patterns.

Notice

: 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 complete.

To ensure rapid completion of readiness monitors, avoid sudden changes in vehicle load and speed (driving up and down hills and/or sudden acceleration).
