Confirmation Driving Pattern
WARNING: This page is about a different car, the 2012 Toyota Corolla. 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" step of the following diagnostic troubleshooting procedure.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation). Refer to DTC CHECK / CLEAR .
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the Techstream on.
- Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [A].
- On the Techstream, enter the following menus to check the fuel-cut status: Powertrain / Engine and ECT / Data List / Idle Fuel Cut.
- Drive the vehicle at a speed between 37 and 75 mph (60 and 120 km/h) for at least 10 minutes [B].WARNING:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- Shift the transaxle to 2nd gear [C].
- Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds [D].WARNING:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
- 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 1500 RPM).
- Allow the vehicle to decelerate until the vehicle speed decreases to less than 6 mph (10 km/h).
- Repeat steps [C] through [E] above at least 3 times in one driving cycle.
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [F].
- 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.
