Connection pins for programming are typically located in the lower section of the ECU. Bosch EDC17 / MED17:
Operating voltage ranges, typically between 5V and 27V depending on the specific line. Common Pin Assignments Bosch Ecu Pinout Datasheet
A visual and text-based list of pins, often divided into sectors like Connector A (engine functions) and Connector B (vehicle systems). Connection pins for programming are typically located in
A Bosch ECU pinout datasheet is a technical document that outlines the pin configuration, electrical connections, and signal descriptions for a specific Bosch ECU model. The datasheet typically includes detailed information on: A Bosch ECU pinout datasheet is a technical
| Bosch ECU Series | Used in vehicles | Connector pins | |------------------|------------------|----------------| | Motronic 1.5–1.8 | BMW E30/E36, VW Golf 2/3 | 35, 55 | | Motronic 3.1–3.8 | Audi A4/S4, VW Passat B5 | 55, 68 | | Motronic MED 9.x | BMW N43/N53, VW EA888 Gen1 | 94, 121 | | EDC15 / EDC16 | VW TDI (ALH, BEW), Mercedes CDI | 48, 64, 96 | | EDC17 / EDC19 | Modern diesels (2010+) | 120, 154 |
Bosch typically uses three main types of connectors across different generations. Knowing which one you have is half the battle.
Note: Actual pinouts vary significantly between ECU part numbers (e.g., 0 261 204 165 vs 0 261 203 735).
