The Bosch ME7.4.5 features a robust aluminum casing designed to withstand engine bay heat and vibrations. It relies on a three-plug configuration, typically labeled , CB , and CC (or referred to by their color-coding: Black, Grey, and Brown). These three modular harness plugs house a total of 112 pins split as follows:

Websites like , SMD Codebook , or RFM (Radio Frequency Management) allow you to search by the marking code.

Manages primary engine actuators, such as fuel injectors, ignition coils, and the electronic throttle body. Comprehensive ME7.4.5 Pinout Database

Always save a full backup (Flash and EEPROM) before attempting any software modifications. If you are currently troubleshooting or tuning, tell me: The printed on your ECU sticker

Ensure the ECU is powered off before establishing the boot connection.

ST 95320 (stores critical data like vehicle options, odometer backups, and IMMO sync keys).

The pinout of a microcontroller is crucial for system design, as it determines how the device interacts with external components and the overall architecture of the PCB (Printed Circuit Board). The ME745 comes in various package types, such as LQFP (Low-profile Quad Flat Package) and BGA (Ball Grid Array), each with its pin configuration. Comprehensive ME7

When you search for “ME745,” you will encounter information for two very different devices. It is essential to identify which one you have before consulting any pinout diagram.

The Bosch ME7.4.5 housing features a three-plug modular interface system. These connectors are divided by specific alpha-numeric indexing systems, commonly designated as Black (Noir), Grey (Gris), and Brown (Marron) plugs, or referred to as Connectors A, B, and C depending on the factory wiring schematic.
