I'll cite the relevant sources. Bosch Motronic ME7.4.5 is a sophisticated engine control unit (ECU) widely used in the automotive industry, particularly within the Stellantis group (formerly PSA), found in models like the Peugeot 206, 207, 307, and Citroën C2, C3, and Berlingo. Understanding its pinout is crucial for professional technicians, tuners, and automotive electricians performing diagnostics, repairs, bench programming, or immobilizer (IMMO) operations. This detailed guide provides a comprehensive overview of the ME7.4.5 pinout, its key functions, and practical applications.

The is a widely utilized engine management system engineered by Bosch for French automotive manufacturers. It is primarily found controlling 1.6L 16V naturally aspirated petrol engines (such as the TU5JP4) across various Peugeot and Citroën (PSA group) platforms , including vehicles like the Peugeot 206, 207, 307 and Citroën C3, C4, and Berlingo. me7.4.5 pinout

Because this ECU uses a (often referred to by their colors: Black, Grey, and Brown), getting the wiring right is critical to avoid frying the processor. Bosch ME7.4.5 Bench Connection Guide

When performing an engine swap (e.g., fitting a 1.6 16V TU5JP4 engine into a different chassis), the ME7.4.5 harness is often retained. Key challenges include:

If you are swapping an ECU, the pinout alone won't get the car started. You will need to extract the 4-digit security code from the EEPROM (95320) to perform a "virgin" reset or an IMMO-off procedure. Safety Precautions I should search for "me7

Note: Pin assignments can vary slightly based on the specific software version and vehicle variant (e.g., automatic vs. manual transmission). Always verify with a multimeter before applying power.

A serial 95320 SPI EEPROM chip . This chip holds vehicle-specific, non-volatile data such as the Vehicle Identification Number (VIN), odometer synchronization parameters, and immobilizer (security) crypto keys.
