Hyundai Elantra: Automatic Transaxle Control System / Description and Operation
| 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.
