To help clarify your specific project goals, could you tell me:
However, in widely cited ME20 configurations (such as the Corsa D application), the following logic typically holds true:
This guide provides the verified pinout configuration for the Bosch ME2.0 module. Bosch ME2.0 Connector Layout
To power up the Bosch ME2.0 ECU on a workbench for reading, writing, or diagnostics, use these exact pin assignments. 1. Power and Ground Connections Plug 1, Pin 2 Switched Ignition (+12V): Plug 1, Pin 1 Main Ground (GND): Plug 1, Pin 4 (or ECU Aluminum Casing) 2. Communication Lines K-Line (Diagnostics): Plug 4, Pin 11 CAN-High (Networking): Plug 4, Pin 1 CAN-Low (Networking): Plug 4, Pin 2 Step-by-Step Bench Setup Procedure bosch me20 pinout verified
Before pinning out the ECU, inspect the connector face closely. The plastic housing contains molded-in numbers at the corners of each plug chamber to indicate pin numbers.
Grounding a specific pad on the circuit board is required before powering on the unit.
Below are the verified pin assignments required to establish boot-mode communication, K-Line diagnostics, and power delivery. 1. Power Supply and Ground Connections To help clarify your specific project goals, could

To help tailor this information to your specific project, tell me: What does your ECU come from, and are you using this pinout for diagnostics, a bench flash, or an engine swap ?
If the internal chip has a corrupted checksum from a prior failed flash write, the K-Line may freeze. You must use boot mode to force a recovery write over the corruption. If you need help finishing your project, tell me: What vehicle make, model, and year are you working on? What specific tool or software are you using to connect?

Before you wire this into your project car, note that the ME20 is not an ME7.5. It uses a weird hybrid strategy:
If you are wiring this ECU into a custom chassis or engine swap project, ensure these pins are properly routed.
A compatible pass-thru interface (e.g., KWP2000, Galletto, MPPS, or specialized factory diagnostic tools). A on the 12V positive line for safety. Step 2: Wire the OBD2 Port to the ECU
The ME20 relies primarily on ISO-9141 K-Line communications for OBD2 diagnostics and chip tuning data transfer.
