CONFIRMATION DRIVING PATTERN
3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P219A-P219F...
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON.
2.
Turn the Techstream on.
3.
Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or
higher [A].
HINT:
The A/C switch and all accessory switches should be off and the shift lever should be in P or
N.
4.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
5.
Drive the vehicle at 60 km/h (38 mph) or higher for 2 minutes or more [B].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
It is acceptable to turn electrical loads on while driving.
6.
Idle the engine for 2 minutes or more [C].
HINT:
The A/C switch and all accessory switches should be off and the shift lever should be in P or
N.
7.
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.
Drive the vehicle at less than 30 km/h (19 mph) for 5 seconds or more [E].
10.
HINT:
11.
Drive the vehicle at 60 km/h (38 mph) or higher for 5 seconds or more [F].

17.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [K].
18.
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.
19.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
20.
Input the DTC: P219A, P219B, P219C, P219D, P219E, P219F, P21A0, P21A1, P21A2 or P21A3.
21.
Check the DTC judgment result.

A
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform the following procedure.
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.
23.
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame
data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if
the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
Sensor 1 refers to the sensor closest to the engine assembly.
When any air-fuel ratio imbalance is detected, the ECM will perform air-fuel ratio feedback control to
make the air-fuel ratio close to the stoichiometric level. This may result in an air-fuel ratio imbalance of
normal cylinders and DTCs may be stored.
PROCEDURE
1.
CHECK FOR ANY OTHER DTCS OUTPUT
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) Read the DTCs.
