3. Select the item: DIAGNOSIS / CARB OBD II / READINESS TESTS. Check that CAT EVAL is INCMPL (incomplete).
4. Drive the vehicle according to the confirmation driving pattern. Note the state of the Readiness Tests. They will change to COMPL (complete) as the CAT evaluation monitors operate.

   If the READINESS CODE of CAT EVAL was INCMPL and any DTC (includes pending codes) was not set, extend the driving time.

   NOTE: If you do not have the hand-held tester, perform again the same confirmation driving pattern after turning OFF the power switch upon finishing the first confirmation driving pattern.
