Diagnostic procedure

Step 1-Step 7:

Initial Learning

Warning: When performing a initial learning, be aware of other vehicles, people, and other impediments to 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.

1. 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.

2. 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 range, 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.
3. Gear shift control learning In D range, with the throttle 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.
4. Inspect learning results Verify that variable speed shock and shift shock have decreased compared to the conditions before learning.
