Bosch Ecu: Pinout Datasheet Best

Have a specific Bosch ECU number you need a pinout for? Leave the 10-digit number in the comments below, and our community will help you locate the best available datasheet.

Most Bosch ECU pinouts are divided into specific functional blocks to help with wiring or bench-flashing: : VCC/Battery (+30) : Constant power. Ignition (+15) : Switched power. GND : Main chassis grounds. Communication : CAN High / CAN Low : High-speed data bus. K-Line : Legacy diagnostic communication. Programming (Bootloader) : bosch ecu pinout datasheet best

: Allows users to search by car brand and ECU type (e.g., EDC16 , EDC17 , ME7.5 ). Have a specific Bosch ECU number you need a pinout for

| Feature | Why It Matters | |---------|----------------| | (e.g., 0 261 204 123) | Prevents mismatches with similar-looking ECUs | | Connector pin numbering diagram | Shows physical layout (often 94, 81, 58, or 48 pins) | | Signal name + type (e.g., AN06 = analog input) | Helps with wiring and diagnostics | | Voltage/current specs (e.g., 5V sensor supply, 12V injector driver) | Avoids damage to ECU or components | | Internal ECU pin function (pull-up, protected output, etc.) | Essential for custom wiring or standalone conversion | | Revision history or application list (vehicle models, years, engine codes) | Confirms compatibility | Ignition (+15) : Switched power
