CONFIRMATION DRIVING PATTERN

HINT:

Connect the Techstream to the DLC3.

1.

Turn the ignition switch to ON and turn the Techstream on.

2.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).

3.

Turn the ignition switch off and wait for at least 30 seconds.

4.

Turn the ignition switch to ON and turn the Techstream on [A].

5.

Start the engine and warm it up until the ECT reaches 75°C (167°F) or higher [B].

6.

With the transmission in 4th gear or higher, drive the vehicle at 60 to 120 km/h (37 to 75 mph) for 10 minutes or more

[C].

7.

1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0136-P0139,...

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].

8.

Read the pending DTCs.

HINT:

If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.

9.

Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

10.

Input the DTC: P0136, P0137, P0138, P0156, P0157 or P0158.

11.

Check the DTC judgment result.

DESCRIPTION

NORMAL

DTC judgment completed

System normal

ABNORMAL

DTC judgment completed

System abnormal

INCOMPLETE

DTC judgment not completed

Perform driving pattern after confirming DTC enabling conditions

N/A

Unable to perform DTC judgment

HINT:

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform steps [C] through [D].

12.

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.

13.

P0139, P013A, P013C and P0159

1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0136-P0139,...

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.

Drive the vehicle at 60 km/h (37 mph), and then decelerate the vehicle by releasing the accelerator pedal for 5 seconds

or more to perform the fuel-cut [C].

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

11.

Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor / O2 Sensor / RL F/C B1S2, RL F/C

B2S2 [D].

12.

Check the Test Value for RL F/C B1S2, RL F/C B2S2.

HINT:

If Test Value displays 0, perform step [C] until it displays a value larger than 0, as the O2 sensor monitor is not

finished.

13.

Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

14.

Read the pending DTC [D].

HINT:

If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.

15.

Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

16.

Input the DTC: P0139, P013A, P013C or P0159.

17.

Check the DTC judgment result.
