Bosch ME7.4.5 Hardware Layout & Connectors

: Reading the internal flash memory chip (ST10F275) often requires grounding a specific boot pad on the circuit board during power-up.

A: Yes. If you are swapping a different engine variant (e.g., NFU) into a car that had a different wiring configuration, repinning the ECU connectors is a common step to ensure all sensors and actuators work correctly.

To help you understand the ME745 pinout, we have created a free downloadable pinout diagram.

Note: Some tools specify alternate power pins, such as and POL5 for direct power injection. Advanced Connection: Boot Mode me745 pinout free

Ultimate Free Guide to Bosch ME7.4.5 ECU Pinout: Bench Flashing, Boot Mode, and Diagnostics

If you are using a flash tool like Piasini, KTAG, or DimSport to read the full micro and eeprom, you must use . This requires connecting to specific points on the ECU board and often soldering resistors. Boot Requirements (Piasini/Similar Tools): Remove: 1 Resistor from the ECU motherboard. Add: 2x 6K8 Ohm Resistors (Boot resistors).

(the 32-pin connector). These pins are standard across most variations of this ECU: Pin Designation Connection Point +12V (Main Power) Constant battery power (K30) +12V (Ignition) Switched ignition power (K15) Ground (GND) Main chassis ground Serial communication for OBD diagnostics Boot Mode Instructions

The most common use of “ME745” refers to the Bosch engine control unit. This advanced ECU is part of Bosch’s Motronic family and was widely used in various PSA (Peugeot/Citroën) vehicles, particularly those equipped with the 1.6-liter TU5JP4 and N6A engines. Whether you need to perform diagnostic checks, map

Complete Bench Connection and Programming Guide for Bosch ME7.4.5

When using a metal positioning frame, ensure the ECU is powered through the frame rather than the main connector to avoid ground loops or short circuits. Visual Verification:

To help pinpoint your specific wiring project, could you share (e.g., KTag, Galletto, MPPS), the exact vehicle model , or if you need the internal boot pin location on the board?

Verify the 6K8 boot resistors are properly soldered. A: Yes

The is a sophisticated management system primarily found in PSA Group vehicles (Peugeot and Citroën). Understanding its pinout is essential for bench flashing, IMMO OFF procedures, or advanced diagnostics. Core Pinout for Bench Connection
