. Ascending Control
When the TCM determines that the vehicle is climbing a hill in E position, the system extends the engagement area of
3rd gear to prevent the transmission from frequently shifting between 3rd and 4th gears, so the vehicle can run smooth
and have more power when needed,
NOTE:
Shift schedules between 3rd and 4th gear stored in the TCM enable the TCM'S fuzzy logic to automatically select themost suitable gear according to the magnitude of a gradient.
Fuzzy logic is a form of artificial intelligence that lets computers respond to changing conditions much like a human
mind would,
. Descending Control
When the TCM determines that the vehicle is going down a hill in E position, the shift-up speed from 3rd to 4th gear
when the throttle is closed becomes faster than the set speed for flat road driving to widen the 3rd gear driving area.This. in combination with engine braking from the deceleration lock-up, achieves smooth driving when the vehicle is
descending,
There are two descending modes with different 3rd gear driving areas according to the magnitude of a gradient stored in
the TCM.
When the vehicle js in 4th gear, and you are decelerating on a gradual hill, or when you are applying the brakes on a steephill, the transmission will downshift to 3rd gear. When you accelerate, the transmission will then return to 4th gear,

. Deceleraiion Control
When the vehicle goes around a corner, and needs to decelerate first and then accelerate. the TCM sets the data for deceleration
control to reduce the number of times the transmission shifts. When the vehicle is decelerating from speeds above 30 mph(,18 km/h), the TCM shifts the transmission from 4th to 2nd earlierthan normal to cope with upcoming acceleration. (cont'd)

Brake System Rubber Parts and Brake Booster
@ Brake Boost€r
Check brake operation by applying the brakes.
lf the brakes do not work properly, check the brake
booster. Replace the brake booster as an assembly if it
does not work properly or if there are signs of leakage
@ Piston cup and Pre3sure cup Inspection
. Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage,
Replace the master cylinder as an assembly if the
pedal does not work properly or if there is damage
or signs of fluid leakage.
. Check for a difference in brake pedal stroke betlveen
quick and slow brake applications, Replace the mas-
ter cylinder if there is a difference in pedal stroke.
O Brake Hoses
Visually check for damage or signs of fluid leakage.
Replace the brake hose with a new one if it is darnaged
or leaking.
@ Caliper PBton Seal and Pkton Boots
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage.
lf the pedal does not operate properly, the brakes drag.
or there is damage or signs of fluid leakage, disassem-
ble and inspect the brake caliper. Replace the boots
and seals with new ones whenever the brake caliper is
disassembled.
