Manufacturer number: 29551869

Country/Region of Manufacture: CN

The Function of TCM :

The functions of the car’s TCM include shifting, controlling pressure, controlling torque, failure protection, self-diagnosis, etc. TCM stands for automatic transmission control module. Once the TCM module fails, an alarm will appear on the dashboard. At the same time, the vehicle will not be able to shift gears, and there will be a lack of acceleration. The vehicle may also stall, etc.

Composition:

TCM consists of industrial computers, card readers, power modules, and I/O boards. ‌These components together constitute the internal structure of TCM and ensure the normal operation of its functions. The industrial computer, as the core processing unit, is responsible for data processing and logic control of the entire system; the card reader is used to read and identify external information, such as identity verification; the power module provides a stable power supply to ensure the stable operation of the system; and the I/O board is responsible for data input and output, connecting external devices and other components within the system‌

regular computer, consisting of a microprocessor (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), and large-scale integrated circuits such as shaping and driving. It can be metaphorically referred to as the “brain of a car”. The voltage working range of ECU is generally 6.5-16V (with a voltage stabilizing device at key internal points), with a working current of 0.015-0.1A and a working temperature of -40 ℃ -80 ℃.
