LEARNING CONTROL
- Transmission shifting hydraulic learning control
Online learning control performance has been improved to absorb variation from vehicle to vehicle and quality aging and to ensure constant high shifting quality.
Learning occurs at each normal shifting under certain conditions, and learned values are saved in the flash ROM. The learned values are not deleted even if power is turned to OFF (even if the battery ground terminal is disconnected).
- Initial learning
The system in which measured data of predetermined driving operations for learning is set to TCM as the initial value is employed to assure high shifting quality from immediately after completion of vehicle. This system does not require the memory box that has been located on the control valve, contributing to cost reduction.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
