: Remove the resistor connection after two seconds; the ECU is now in boot mode and ready for reading/writing. ⚠️ Safe Bench Procedures
Since "ME745" is ambiguous, follow this step-by-step forensic approach:

The main interface is split across multiple connector chambers (commonly referred to as blocks or connectors A, B, and C). To identify your specific connection points, reference the free technical layout on platforms like the ECU Design Pinout Database . Essential Power and Data Ground Pin Identification
Where “free pinout” results usually come from : Remove the resistor connection after two seconds;
What are you using to read the ECU? (e.g., KESS, MPPS, KTAG, or a multimeter)
Bench connection requires isolating the basic operational lines: continuous main power, ignition-switched power, ground chassis reference, and diagnostic communication data buses. The master pin configurations listed below enable communication with standard diagnostic scanners and chip-tuning interfaces. 1. Power and Ground Pins Plug C, Pin H4 Ignition-Switched Power (+12V switched): Plug C, Pin F4 Chassis Electrical Ground (GND): Plug C, Pin H2 2. Diagnostic and Data Communication Bus lines K-Line Diagnostic Link (ISO-9141): Plug C, Pin B4 CAN-High Network Line: Plug A, Pin A3 CAN-Low Network Line: Plug A, Pin A4 Flashing and Modification Protocols Essential Power and Data Ground Pin Identification Where
