Me745 Pinout Free May 2026
Misidentifying even a single pin can lead to:
Having a clear, free pinout diagram allows you to probe voltages with confidence, identify faulty components, and design proper PCB layouts.
Follow the positive terminal of the input capacitor (typically 10µF–22µF, rated for 25V or more). That capacitor connects directly to VIN (pin 5) .
Search for "SOT-23 marking ME745" or "marking 745 regulator" on Google Images. Often, you will find a photo of the same component on a known board (e.g., from a dashcam, LED driver, or battery charger).

Bosch ME7.4.5 engine control unit (ECU), commonly used in Peugeot and Citroën vehicles (like the 206, 207, 307, C2, and C4), has specific pin assignments for power, grounding, and communication. This model typically features a 3-plug system (32-48-32 pins), where Plug C (Gray) is primarily used for bench connections and boot mode. Bosch ME7.4.5 Bench Pinout (Plug C)
For standard reading or diagnostic connection on the bench, use the following pin assignments for the gray connector: +12V Power Supply (Main) +12V Ignition (Switch) Ground (GND) K-Line (Data) Boot Mode Instructions To put the ME7.4.5 into bootstrap mode
for deep reading or writing (e.g., using Piasini or similar tools), internal modifications are required: Resistor Setup 6.8k Ohm (6k8) resistors to the designated internal pads. Component Removal : One specific internal resistor must be from the ECU board to enable the boot state. Misidentifying even a single pin can lead to:
: Lay-by pins for communication are typically located in the lower part of the ECU board. Common Applications Vehicle Model Engine Type Common ECU Variant Citroën C2 VTS 1.6 16v (TU5JP4S) Peugeot 207 / 307 1.6 16v (TU5JP4) Citroën C4 ME7.4.5 (Motronic)

For those working on the Bosch ME7.4.5 ECU commonly found in PSA Group (Peugeot/Citroën) 1.6L 16V NFU engines, here is the essential pinout information for bench programming and boot mode. Bosch ME7.4.5 Bench Pinout (Plug C)
To connect your programmer (like KTAG, Galletto, or KT200) on the bench, use the following pin assignments for Plug C: +12V (Power Supply): Pin H2 +12V (Ignition): Pin F4 Ground (GND): Pin H4 K-Line: Pin B4 Boot Mode Instructions
Entering boot mode on this specific ECU typically requires internal hardware modifications rather than just a single grounding pin: Add Resistors: You must add two 6.8k Ohm ( ) resistors to the board.
Remove Resistor: One specific resistor must be removed to enable the boot sequence.
Boot Pins: Specific "lay-by" pins for boot/CNF1 are located in the lower section of the ECU board. Alternative "Full System" Connections
Newer tools such as DFB Technology offer "Full System" drivers that allow for full Micro and EEPROM reading/writing via pinout without opening the ECU, which is significantly safer for recovery and checksum corrections.
When performing these operations, ensure a stable power supply of at least 13.5V is maintained to prevent data corruption during the read/write process. Always verify the hardware version and software numbers on the ECU sticker before proceeding with any modifications. Bosch ME7.4.5 ECU Pinout Guide | PDF | Computers - Scribd
