TCM

The TCM which is adapted to the new small sized automatic transaxle (A4CF2) is separated from the ECM and deliver information via CAN communication.





- TLE6288 current control chip

The TLE6288 current control chip is installed into the TCM to regulate the solenoid control current and control the oil pressure securely according to the change of the temperature and voltage. In this case, the control signal of solenoid valve is divided into the Peak signal and the Hold signal.
1. Peak: The 12 voltage signal applied to move the solenoid plunger quickly.
2. Hold: The signal applied to keep holding the pulled solenoid valve.

FPC (FLEXIBLE PRINTED CIRCUIT) HARNESS

The FPC (Flexible Printed Circuit) harness is composed of the thin and flat copper in the insulating film like electric wire.
