Designed for gasoline direct injection (GDI) engines.
The useful datasheet isn't a colorful diagram. It’s a dense table with columns:
The is an indispensable tool for anyone doing heavy-duty automotive work. Whether you are performing an engine swap or debugging a sophisticated tuning issue, accurate pinout data ensures that every sensor and actuator is mapped correctly. Always verify your pinout against your specific ECU part number to avoid irreversible damage. If you're finding this helpful, AI responses may include mistakes. Learn more Bosch Ecu Pinout Datasheet
Dedicated lines for vehicle network data, primarily CAN-Bus (CAN-High/CAN-Low) and K-Line. 2. Deciphering Bosch ECU Naming Conventions
When modifying or troubleshooting an engine management system, a handful of specific pins are used most frequently. Designed for gasoline direct injection (GDI) engines
This write-up summarizes typical Bosch automotive ECU pinout information, common signal functions, connector naming conventions, and practical notes for diagnostics and wiring. Bosch designs many ECU families (Motronic, MED, EDC, ME, etc.), so treat this as a general reference — always verify against the exact part number and manufacturer datasheet for the specific unit.
Software applications bundled with hardware tools like Alientech KESS3, Dimsport New Trasdata, or Hexprog provide highly detailed photographic bench and boot pinouts. Safety Guidelines for Probing ECU Pins Whether you are performing an engine swap or
Labeled as GND , Mass , or V- . These ensure the circuit completes cleanly.
| Function | Pin Number | | ----------------- | ---------- | | | 1 | | Mass (GND) | 2 | | IGN/15 (key-on) | 7 | | CAN High | 46 | | CAN Low | 33 |
Software used for reflashing Bosch ECUs (like or CMDFlash ) often includes connection manuals that show pinouts for bench programming. Structure of a Typical Bosch Pinout
