AUTOMATIC TRANSAXLE

23A-25

Use the scan
tool (MUT-II) to
stop the
INVECS-II
function.
Selector lever
position: D (on a
flat and straight
road.)

Monitor data list No. 11,
23, and 63 with the scan
tool (MUT-II).
<Vehicles without sport
mode>
(1)Accelerate to 4th gear
at a throttle position sensor
output of 1.5V (accelerator
opening angle of 30 %).
(2)Slowly decelerate to a
stop.
(3)Accelerate to 4th gear
at a throttle position sensor
output of 2.5 V (accelerator
opening angle of 50%).
(4)While driving at 60 km/h
(37 mph) in 4th gear, shift
down to 3 range.
(5)While driving at 40 km/h
(25 mph) in 3rd gear, shift
down to 2 range.
(6)While driving at 20 km/h
(12 mph) in 2nd gear, shift
down to L range.
<Vehicles with sport
mode>
(1)Accelerate to 4th gear
at a throttle position sensor
output of 1.5V (accelerator
opening angle of 30 %).
(2)Slowly decelerate to a
stop.
(3)Accelerate to 4th gear
at a throttle position sensor
output of 2.5 V (accelerator
opening angle of 50%).
(4)Select to the sport mode
while driving at 60 km/h
(37 mph) in 4th gear, shift
down to 3rd gear.
(5)While driving at 40 km/h
(25 mph) in 3rd gear, shift
down to 2nd gear.
(6)While driving at 20 km/h
(12 mph) in 2nd gear, shift
down to 1st gear.

For (1), (2) and
(3), the reading
should be the
same as the
specified output
shaft speed, and
no abnormal shift
shocks should
occur.
For (4), (5) and
(6), downshifting
should occur
immediately after
moving the
selector lever.
