Hyundai Venue: Automatic Transaxle Control System / Transaxle Control Module (TCM). Description and operation
Hyundai Venue (QX) (2020-2024) Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / Transaxle Control Module (TCM). Description and operation
| Description |
| • |
Monitors the vehicle's operating conditions to determine the optimal
gear setting.
|
| • |
Performs a gear change if the current gear setting differs from the
identified optimal gear setting.
|
| • |
Determines the need for damper clutch (D/C) activation and engages the
clutch accordingly.
|
| • |
Calculates the optimal line pressure level by constantly monitoring
the torque level and adjusts the pressure accordingly.
|
| • |
Diagnoses the automatic transaxle for faults and failures.
