CONFIRMATION DRIVING PATTERN
1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2195-P2198;...
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.
Start the engine, and warm it up until the ECT reaches 75°C (167°F) or higher [A].
7.
On the Techstream, enter the following menus to check the fuel-cut status: Powertrain / Engine and
ECT / Data List / Idle Fuel Cut.
8.
Drive the vehicle at between 60 and 120 km/h (38 and 75 mph) for at least 10 minutes [B].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
9.
Shift the transmission to 2nd gear [C].
10.
Accelerate the vehicle to 64 km/h (40 mph) or more by depressing the accelerator pedal for at least
10 seconds [D].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
11.
Soon after performing step [D] above, release the accelerator pedal for at least 4 seconds without
depressing the brake pedal in order to execute fuel-cut control [E].
HINT:
Fuel-cut is performed when the following conditions are met:
Accelerator pedal is fully released.
Engine speed is 2500 rpm or more (fuel injection returns at 1000 rpm).
12.
Allow the vehicle to decelerate until the vehicle speed decreases to less than 10 km/h (6 mph).
13.
Repeat steps [C] through [E] above at least 3 times in one driving cycle.
14.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [F].
15.
Read the pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
16.
1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2195-P2198;...
If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
17.
Input the DTC: P2195, P2196, P2197 or P2198.
18.
Check the DTC judgment result.
TECHSTREAM
DISPLAY
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 [B] through [F] again.
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.
20.
