The ME7.4.5 uses multiple connectors (often categorized by color or pin count). Key signals on the include: CAN Bus: Pin A3 (CAN High) and Pin A4 (CAN Low). Cooling Fan Control: Pin B1 and Pin C1. Clutch Sensor: Pin D1.
STMicroelectronics ST10F275 (or ST10F280 in some variants). Internal Flash: 832 KB or 1024 KB embedded memory. EEPROM: 95320 (used for immobilizer data and adaptations). 2. Pinout Configuration for Bench Mode me7.4.5 pinout
Bosch ME7.4.5 is a common Engine Control Unit (ECU) used primarily in Peugeot and Citroën (PSA) vehicles with the 1.6 16v (TU5JP4) engine
: Remove one specific resistor on the ECU board and add two 6.8k ohm resistors . If you need: The ME7
Black Connector -> Pin H4 (or connect directly to the metal ECU casing) Communication Lines K-Line (Diagnostics): Grey Connector -> Pin A4
To put the ME7.4.5 into Boot Mode (required for full reading/writing of the internal flash), you typically need to modify the circuit board slightly before connecting your programmer (like Kess, Galletto, or Piasini). Add Resistors : Solder two 6.8k Ohm (6k8) resistors to the designated boot points on the PCB. Remove Resistor Clutch Sensor: Pin D1
Are you trying to do a modification?
The ECU is powered by two main circuits: permanent battery power (PWR) and switched power (IGN), which is activated by the ignition key. These are distributed across several pins:
Add two 6.8k ohm (6k8) resistors and remove one existing resistor as specified in the Bosch ME7.4.5 ECU Pinout Guide on Scribd .
Note: Some variant ECUs (like for automatic transmissions) may have extra pins for TCU communication. The manual transmission pinout is covered here.
