Confirmation Driving Pattern
This confirmation driving pattern is used in the "PERFORM CONFIRMATION DRIVING PATTERN" procedure of the following diagnostic troubleshooting procedure.
- Connect Techstream to the DLC3 (a).
- Turn the power switch on (IG) (b).
- Turn the tester on (c).
- Clear the DTCs (See CHECK MODE PROCEDURE ) (d).
- Put the engine in inspection mode (See SFI SYSTEM ), warm it up until the ECT reaches 75°C (167°F) or higher (e).
- On Techstream, select the following menu items to check the fuel-cut status: Powertrain / Engine / Data List / Idle Fuel Cut (f).
- Drive the vehicle at between 40 mph (64 km/h) and 75 mph (120 km/h) for at least 10 minutes (g).
- Change the transmission to the B position (h).
- Drive the vehicle at a proper vehicle speed to perform fuel-cut operation (i).
HINT:
Fuel-cut is performed when the following conditions are met:
- Accelerator pedal is fully released.
- Vehicle speed is 55 mph (88 km/h) or more (fuel injection resumes at 1,000 rpm).
- Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds (j).
- Soon after performing step (j) above, release the accelerator pedal for at least 10 seconds without depressing the brake pedal, in order to execute fuel-cut control (k).
- Allow the vehicle to decelerate until the vehicle speed declines to less than 40 mph (64 km/h) (l).
- Repeat steps from ( h) through ( k) above at least 3 times in one driving cycle (m).
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.
