Automatic Transaxle Control System Hyundai Santa Fe III

Automatic Trans 114 illustrations ~4210 words

Description

Automatic transaxle system relies on various measurement data to determine the current control status and extrapolate the necessary compensation values. These values are used to control the actuators and achieve the desired control output. If a problem with the drivetrain, including the transaxle, has been identified, perform self-diagnosis and basic transaxle inspection (oil and fluid inspection) and then check the control system's components using the diagnosis tool.

Transaxle Control Module (TCM) Learning

When shift shock is occurred or parts related with the transaxle are replaced, TCM learning should be performed.

In the following case, TCM learning is required.

  1. Transaxle assembly replacement
  2. TCM replacement
  3. TCM upgrading

Scheme 84

Scheme 84: TCM learning procedure
  1. Automatic Transaxle Fluid (ATF) temperature: 40 ~ 100°C (104 ~ 212°F)
  2. Static learning Repeat the below shift pattern four times or more while depressing the brake.
  3. Driving learning Drive the vehicle from a stop in D through all gears 1st, 2nd, 3rd, 4th, 5th and 6th gear while holding the throttle steady at the specified Throttle Position Sensor (TPS) value (15~25%).

Transaxle Control Module (TCM) is the automatic transaxle's brain. The module receives and processes signals from various sensors and implements a wide range of transaxle controls to ensure optimal driving conditions for the driver. TCM is programmed for optimal response to any on-road situation. In the event of a transaxle failure or malfunction, TCM stores the fault information in memory so that the technician may reference the code and quickly repair the transaxle.

Functions

  1. Monitors the vehicle's operating conditions to determine the optimal gear setting.
  2. Performs a gear change if the current gear setting differs from the identified optimal gear setting.
  3. Determines the need for damper clutch (D/C) activation and engages the clutch accordingly.
  4. Calculates the optimal line pressure level by constantly monitoring the torque level and adjusts the pressure accordingly.
  5. Diagnoses the automatic transaxle for faults and failures.

TCM installation bolt: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft) TCM bracket installation bolt/nut: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft) CAUTION: Perform TCM learning after replacing the transaxle to prevent slow transaxle response, jerky acceleration and jerky startup. (Refer to Automatic Transaxle Control System - " «Repair Procedures»(/hyundai/santa-fe/iii-2012-2016/remont/automatic-trans/#automatic-transaxle-control-system) ")

TCM Problem Inspection Procedure

  1. TEST TCM GROUND CIRCUIT: Measure resistance between TCM and chassis ground using the backside of TCM harness connector as TCM side check point. If the problem is found, repair it. Specification: Below 1ohms
  2. TEST TCM CONNECTOR: Disconnect the TCM connector and visually check the ground terminals on TCM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.
  3. If problem is not found in Step 1 and 2 , the TCM could be faulty. If so, make sure there were no DTC's before swapping the TCM with a new one, and then check the vehicle again. If DTC's were found, examine this first before swapping TCM.
  4. RE-TEST THE ORIGINAL TCM: Install the original TCM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original TCM with a new one. If problem does not occur, this is intermittent problem (Refer to "Intermittent Problem Inspection Procedure" in Basic Inspection Procedure).

Transaxle Oil Temperature Sensor (OTS) monitors the automatic transaxle fluid's temperature and conveys the readings to TCM. It is an Negative Thermal Coefficient (NTC) sensor whose resistance has an inversely proportional relationship with the temperature level. Data produced by this sensor is used to identify damper clutch activation and deactivation zones within the low temperature and high temperature range and to compensate hydraulic pressure levels during gear changes.
