POSSIBLE CAUSE DESCRIPTION CHART
Initial Learning
| WARNING | When performing initial learning, be aware of other vehicles, people, and other impediments in order to avoid an accident. |
Note. While self-learning control gradually reduces shock during normal driving, initial learning is performed to initially learn a certain amount of driving conditions.
- Warm-up Increase the ATF temperature by leaving the vehicle idling or performing city driving. Verify that the ATF temperature is between 66-110°C {151-230°F}. If the ATF temperature is outside this range, work to bring it inside the range. CAUTION: Do not raise the ATF temperature by stalling the engine. NOTE: If the ATF temperature is not between 66-110°C {151-230°F} , initial learning cannot be performed. Before learning, inspect for variable shift shock.
- Garage shift learning With the vehicle standing still, depress the brake pedal and keep the selector lever in N position for 3 s. Then, shift the selector lever from the N position into D position, and maintain in this condition for 3 s. Repeat this procedure 5 times. Then repeat it 5 times in the same way for R position.
- Gear shift control learning In D position, with the accelerator opening between 25-30% , drive until you reach 6th gear and a vehicle speed of 80 km/h {50 mph} or higher. Then, release the accelerator pedal and coast, and bring the vehicle to a stop in at least 60 s. Repeat this procedure 10 times.
- Inspect learning results Verify that variable speed shock and shift shock have decreased compared to the conditions before learning.
