CONFIRMATION DRIVING PATTERN
HINT:
Performing this confirmation driving pattern will activate the catalyst efficiency monitor. This is very useful for verifying the
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON.
2.
Turn the Techstream on.
3.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
4.
Turn the ignition switch off and wait for at least 30 seconds.
5.
Turn the ignition switch to ON and turn the Techstream on.
6.
Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor.
7.
Check that Catalyst Efficiency / Current is Incomplete.
8.
Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [A].
9.
Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [B].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
Drive the vehicle while keeping the engine load as constant as possible.
10.
Turn the ignition switch off and wait for at least 30 seconds [C].
11.
Turn the ignition switch to ON and turn the Techstream on.
12.
Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [D].
13.
Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [E].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
Drive the vehicle while keeping the engine load as constant as possible.
The monitor item will change to Complete as the Catalyst Efficiency monitor operates [F].
14.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
15.
Check if any DTCs (pending DTCs) are stored.
HINT:
If the monitor item does not change to Complete, and no pending DTCs are stored, perform the following
procedure.
16.
Drive the vehicle at a speed between 75 and 100 km/h (47 and 63 mph) for 10 minutes or more [G].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
Drive the vehicle while keeping the engine load as constant as possible.
The monitor item will change to Complete as the Catalyst Efficiency monitor operates [H].
17.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
18.
Check if any DTCs (pending DTCs) are stored.
HINT:
If the monitor item does not change to Complete, and no pending DTCs are stored, extend the driving time.
19.
If no pending DTC is output, perform a universal trip and check for permanent DTCs

HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.
CONDITIONING FOR SENSOR TESTING
HINT:
(a) Connect the Techstream to the DLC3.
(b) Start the engine and warm it up with all the accessories switched OFF until the engine coolant temperature stabilizes.

HINT:
HINT:
Malfunctioning areas can be identified by performing the Control the Injection Volume for A/F sensor function provided in the
Active Test. The Control the Injection Volume for A/F sensor function can help to determine whether the Air-Fuel Ratio (A/F)
sensor, Heated Oxygen (HO2) sensor and other potential trouble areas are malfunctioning.

The following instructions describe how to conduct the Control the Injection Volume for A/F sensor operation using the
Techstream.
Connect the Techstream to the DLC3.
1.
Start the engine and turn the Techstream on.
2.
On the Techstream, enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Injection Volume for
A/F sensor.
4.
Perform the Active Test operation with the engine idling (press the RIGHT or LEFT button to change the fuel injection volume.)
