6 Selector lever position: N (Carry out on a flat and straight road) Selector lever position and vehicle speed
  1. Idling in 1st gear (Vehicle stopped)
  2. Driving at constant speed of 20 km/h in 1st gear
  3. Driving at constant speed of 30 km/h in 2nd gear
  4. Driving at 50 km/h in 3rd gear with accelerator fully closed
  5. Driving at constant speed of 50 km/h in 4th gear
 (2) 1st, (4) 3rd, (3) 2nd, (5) 4th Shift condition
(2)0%, (4)100%, (3) 100%, (5)100% Low and reverse solenoid valve
(2) 0%, (4) 0%, (3) 0% Underdrive solenoid valve
(1) 100%, (2) 0%, (3) 100% Second solenoid valve
(2) 100%, (3) 100%, (4) 0% Overdrive solenoid valve
(1) 0km/h
(4) 50km/h		 Vehicle speed sensor
(4) 1,800~2,100rpm Input shaft speed sensor
(4)1,800~2,100rpm Output shaft speed sensor
7 Selector lever position: D (Carry out on a flat and straight road)
  1. Accelerate to 4th gear at a throttle position sensor output of 1.5V (accelerator opening angle of 30 %).
  2. Gently decelerate to a standstill.
  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 in 4th gear, shift down to 3rd gear.
  5. While driving at 40 km/h in 3rd gear, shift down to 2nd gear.
  6. While driving at 20 km/h in 2nd gear, shift down to 1st gear.
 For (1), (2) and (3), the reading should be the same as the specified output shaft torque, and no abnormal shocks should occur.
For (4), (5) and (6), downshifting should occur immediately after the shifting operation is made.		 Malfunction when shifting
Displaced shift points
Does not shift
Does not shift from 1 to 2 or 2 to 1
Does not shift from 2 to 3 or 3 to 2
Does not shift from 3 to 4 or 4 to 3
8 Selector lever position: N (Carry out on a flat and straight road) Move selector lever to R range drive at constant speed of 10km/h The ratio between input and output shaft speed sensor data should be the same as the gear ratio when reversing. Does not shift
