Confirmation Driving Pattern
WARNING: This page is about a different car, the 2009 Toyota Tacoma. However, it is still accessible from the selected car via links, so may be relevant.
This confirmation driving pattern is used in the "PERFORM CONFIRMATION DRIVING PATTERN" procedure of the following diagnostic troubleshooting procedure.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream ON.
- Clear DTCs (See DTC CHECK/CLEAR ).
- Start the engine, and warm it up until the ECT reaches 70°C (158°F) or higher.
- On the Techstream, enter the following menus: Powertrain/Engine and ECT/Active Test/Control the Injection Volume for A/F sensor.
- Drive the vehicle at between 38 mph (60 km/h) and 75 mph (120 km/h) for at least 10 minutes.
- Change the transmission to 2nd gear.
- Drive the vehicle at proper vehicle speed to perform fuel-cut operation (refer to the following HINT).
HINT:
Fuel-cut is performed when the following conditions are met:
- Accelerator pedal fully released.
- Engine speed is 2500 rpm or more (fuel injection returns at 1000 rpm).
- Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds.
- Soon after performing step (j) above, release the accelerator pedal for at least 4 seconds without depressing the brake pedal, in order to execute fuel-cut control.
- Allow the vehicle to decelerate until the vehicle speed declines to less than 6 mph (10 km/h).
- Repeat steps from ( h) through ( k) above at least 3 times in one driving cycle.
HINT:
Completion of all A/F sensor monitors is required to change the value in Test Result.
CAUTION: Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive patterns.
