Me745 Pinout __link__ Free
The Bosch ME7.4.5 (often referred to as ME745) is a widely used Engine Control Unit (ECU) in PSA Group vehicles—Peugeot and Citroën—from the mid-2000s to the 2010s. Whether you are performing a tuning project, repairing a vehicle, or attempting to clone an ECU for a swap, having an accurate pinout diagram is essential.
To get the ECU to power up and communicate, you need to supply power, a reliable ground, and an ignition trigger. Pin A4 (on the Black 32-pin connector) Switched (Ignition): Pin F2 (on the Black connector) Ground (GND): Pin M1 and M2 (on the Black connector) K-Line (Diagnostic): Pin H1 (on the Black connector) CAN High: Pin A3 (on the Black connector) CAN Low: Pin A4 (on the Black connector)
⚠️ Always before disconnecting any ECU connectors to prevent electrical shorts or airbag system warnings.
Working with an ECU requires precision. Taking shortcuts or making incorrect wire connections can permanently damage the engine computer. Never let your bench power supply drop below me745 pinout free
Follow the positive terminal of the input capacitor (typically 10µF–22µF, rated for 25V or more). That capacitor connects directly to .
Dedicated heavily to engine-side sensors, including oxygen sensors, knock sensors, and temperature readings.
For standard reading, writing, and diagnostic wake-up, connect your bench harness using the following pin map: Bosch ME7.4.5 (Citroen Peugeot) IMMO OFF The Bosch ME7
Fortunately, the ME745 follows a relatively standard pinout pattern for a 6-pin or 8-pin SOT-23 package.
: Some instructions specify adding two 6K8 resistors and removing one internal resistor to enable Bootstrap mode. Reference Resources

* **Digital I/O Pins:** The ME745 has 54 digital I/O pins, which can be used for connecting external devices such as LEDs, buttons, and sensors. * **Analog Input Pins:** The board has 16 analog input pins, which can be used for connecting analog sensors such as accelerometers, gyroscopes, and pressure sensors.
A standard KTAG cable or similar OBD bench cable (e.g., F32GN037C) is often used.
Tuning or cloning an ME7.4.5 often requires removing the unit from the vehicle and connecting it to a bench programmer (such as KESSv2, KTAG, Galletto, or MPPS). To read the ST10F275 microprocessor or the EEPROM on the bench, configure your pin bridge configuration as follows: Required Bench Harness Mapping: Connect to Pin G4 (Black Connector) +12V Ignition: Connect to Pin F4 (Black Connector) Ground (GND): Connect to Pin A3 or Pin H4 (Black Connector) K-Line: Connect to Pin B1 (Black Connector) Boot Mode Activation (For Boot-Strap Loading)
