Always double-check the small numbers embossed on the plastic connector housing to avoid reversing polarity.
For a quick reference, here is the complete pin assignment in a more traditional table format. This combines all known pin definitions for the ME745.
Working on the internal board of an ECU requires precision. Ensure you are familiar with soldering techniques before attempting boot mode. 4. Free Resources for ME745 Pinout
The Bosch ME7.4.5 engine control unit (ECU) manages fuel injection and ignition for various PSA (Peugeot and Citroën) vehicles equipped with 1.6-liter 16v engines. Pinout data is essential for bench flashing, diagnostics, chip tuning, and repairing these modules. 📋 Bosch ME7.4.5 Connector Breakdown me745 pinout free
📌 Pin 7 (NC) may be used for internal test modes in some revisions. Always treat it as "do not connect" unless the datasheet specifies otherwise.

The is a highly integrated, step-down (buck) switching regulator commonly found in consumer electronics, including smart TVs, set-top boxes, routers, and industrial control boards. Manufactured by Nanjing Micro One Electronics (Microne), this IC is prized for its efficiency, wide input voltage range, and ability to deliver up to 2A of continuous output current . Always double-check the small numbers embossed on the
Many technical websites charge for "premium" datasheets or pinout diagrams. However, the ME745 datasheet is publicly available from Microne’s official website and semiconductor aggregators like , Datasheet4U , or AllDatasheet . Use the following search string to locate the original PDF:
Apply +12V power, hold for 3 seconds, then remove the ground bridge. The processor is now ready to read/write. Common Diagnostic and Wiring Troubleshooting
