• Preface on EDC7C4-6 / EDC16C31

– They’re essentially the same unit. It’s an EDC7 inside an EDC16 housing.

– Two hardware variants:

• Pure K-line: The OBD socket has K-line; identification and diagnostics work.
• CAN: the socket has both CAN and K-line, but K-line is NOT connected to the ECU. That said, all CAN ECUs still support reprogramming over K-line, but only with a direct connection to the ECU connector

– CAN ECUs are the most troublesome: The reprogramming implementation is extremely clumsy, so the CAN bus speed doesn’t match the operating speed. Therefore, if the vehicle has a tachograph or transmission control unit (possibly other add-ons), programming over CAN in-vehicle will be IMPOSSIBLE. You’ll get an error when entering programming mode and the ECU will stop responding. 

It’s not bricked: Just disconnect and reconnect the battery terminal and it will “come back.” To program such ECUs, you must remove the unit and connect directly to the connector (CAN or K-line).

Solution: After switching the ignition ON, wait 30 seconds before pressing OK.

–  Power on the bench: All 24 V ECUs work fine on 12 V when on bench.

– Read/write content: The bootloader reads a complete full—a file containing both external and internal flash (FullFlash); writing is done in the same full format.

• Preface on EDC17

– Reading: calibration area only.

– Writing: Depending on the file, if full software writing is possible, the software will ask about it. You can use files read in BSL mode to writing normal.
