- Connect the intelligent tester to the DLC3.
- Turn the engine switch on (IG).
- Turn the tester ON.
- Clear DTCs (if set) (see DTC CHECK / CLEAR ).
- Enter the following menus: DIAGNOSIS / CARB OBD II / READINESS TESTS.
- Check that CAT EVAL is INCMPL (incomplete).
- Start the engine and warm it up.
- Drive the vehicle at between 40 mph and 70 mph (64 km/h and 113 km/h) for at least 10 minutes.
- Note the state of the Readiness Tests items. Those items will change to COMPL (complete) as CAT EVAL monitor operates.
- On the tester, enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PENDING CODES; then check if any DTCs (any pending DTCs) are set.
HINT:
If CAT EVAL does not change to COMPL, and any pending DTCs fail to set, extend the driving time.
