(i) Drive the vehicle at a proper vehicle speed to perform fuel-cut operation.

(j) Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds. HINT:

Fuel-cut is performed when the following conditions are met:

• Accelerator pedal fully is released.

• Engine speed is 2,500 rpm or more (fuel injection resumes at 1,000 rpm).

(k)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. (l) Allow the vehicle to decelerate until the vehicle speed declines to less than 6 mph (10 km/h). (m)Repeat steps from (h) through (k) above at least 3 times in one driving cycle. HINT:
