Hyundai Tucson: Filling check

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Intelligent Manual Transaxle (IMT) System /  IMT System Learning Procedures / Filling check

WARNING

  • The procedure below shows about residual air check and removing it if necessary by using the diagnostic tool after refilling the IMT system with clutch fluid.
  • The "IMT filling check" procedure should be performed after reinstalling the hydraulic line related parts such as Concentric Slave Cylinder, Clutch Tube, IMT System Actuator.
  • The "IMT filling check" procedure should be performed after removing and reinstalling the transmission from the engine such as clutch and fly wheel replacement
  1. Fill the reservoir with clutch fluid to the "MAX" level.

Specified fluid : DOT4-LV (Recommended). DOT3 or DOT4 (Usable)

  1. Perform the "IMT filling check" using diagnostic tool.

WARNING

  • To prevent accidents caused by vehicle movement, perform the "IMT filling check" after the engaging the parking brake.
  • If fluid is below MIN level while performing air bleeding, replenish fluid with MAX level.

WARNING

  • Check the below sensor data by using the diagnostic tool.
  • Engine power on
  • Current gear "N"
  • Accel. Position Sensor 0 %
  • Clutch pedal sensor 0 %

  1. If the IMT filling check failed, perfome the air bleeding procedures.

WARNING

  • Filling check status can be checked through the cluster lamp.
  • Prior to filling check. E lamp blinks. After filling check is completed, the "E" lamp lights up.
  1. IMT system actuator forced operation should be performed, if replaced IMT system actuator with a new one.

WARNING

After complete the filling check, selecting combo box pops up for choosing.

  1. When the engine power is turned on. the touch point learning would be performed automatically

WARNING

If driver interrupt the learning by manipulating any pedals, the learning would be stopped. When the condition of the learning is satisfied, the learning would be performed anytime.

Clutch touch-point learning

WARNING

  • Clutch touch-point learning status can be checked through the cluster lamp.
  • Prior to learning. "E" lamp turns on. After learning, the current gear position (N) replaces the "E" lamp and blinks.
  1. Check the below sensor data by using the diagnostic tool.

(1) Current gear "N"

(2) Accel. Position Sensor 0 %

(3) Clutch pedal sensor 0 %

WARNING

  • Engine power on
  • Current gear "N"
  • Accel. Position Sensor 0 %
  • Clutch pedal sensor 0 %
  1. When the engine power is turned on. the touch point learning would be performed automatically.

WARNING

If driver interrupt the learning by manipulating any pedals, the learning would be stopped. When the condition of the learning is satisfied, the learning would be performed anytime.

  1. Check a sensor data value.

"Touch-point learning finished"

WARNING

  • If the shift lever is located "N" but the sensor data of "Current gear" isn't displayed "N", inspection of the lever and control cable is required.

    (Refer to IMT(intelligent Manual Transaxle) Control System - "Control Cable")

Torque - Stroke learning

WARNING

  • Clutch torque - Stroke learning status can be checked through the cluster lamp.
  • Prior to learning, the current gear position (N) lamp blinks. After learning, the current gear position (4) lamp lights up.
  1. Drive the vehicle with below condition.

(1) Launch the vehicle and shift gear l23 rapidly under 30 kph.

(2) Drive the vehicle with below APS 30% in 3rd gear for about 20 seconds up to 70 kph. (APS have to be keep the least of fluctuating)

(3) Shift the gear to 3rd 4th above 70 kph vehicle speed.

  1. Check a sensor data value.
