Confirmation Driving Pattern
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 (even if no DTCs are stored, perform the clear DTC operation).
- Start the engine, and warm it up until the ECT reaches 75°C (167°F) or higher [A].
- On Techstream, enter the following menus to check the fuel-cut status: Powertrain / Engine and ECT / Data List / Idle Fuel Cut.
- 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.
- Shift the transmission to 2nd gear [C].
- Accelerate the vehicle to 64 km/h (40 mph) or more by depressing the accelerator pedal for at least 10 seconds [D].
- 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).
- Allow the vehicle to decelerate until the vehicle speed decreases to less than 10 km/h (6 mph).
- Repeat steps [C] through [E] above at least 3 times in one driving cycle.
- Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
- Input the DTC: P2195 or P2196.
- Check the DTC judgment result [F].TESTER DISPLAY DESCRIPTION
Tester 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
UNKNOWN - Unable to perform DTC judgment
- Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
HINT:
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [B] through [F].
- If the test result is UNKNOWN, enter the following menus: Powertrain / Engine and ECT / Trouble Code / Pending.
- Read Pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
- If the test result is INCOMPLETE or UNKNOWN and no pending DTC is output, perform a universal trip and check for permanent DTCs (See DTC CHECK / CLEAR
).
HINT:
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
