Issue:
While writing an edc17 c46 Dpf off file using the KT200II ECU Programmer, the process gets stuck at 14%.
Possible Reasons and Solutions:
1. Voltage Issue:
It’s common for edc17 to require higher voltage.
Normally, 12.3/12.4V works perfectly, but in this case, consider using a 14.2V adapter.
The adapter from the Flex tool has been reported to work without issues.
2. Manual Checksum instead of Auto checksum:
It’s common for edc17 to require manual checksums (chks)
3. Bad File:
The problem might be due to changes in the OTP (One-Time Programmable) area of the file.
Refer to the solution for OTP issues “KT200 EDC17CP42 Bench ECU Clone Non-Erasable Sector Solution”: https://www.kt200.org/kt200-edc17cp42-bench-ecu-clone-non-erasable-sector-solution/
User Experiences:
One user tested with at least 10 edc17 variants (BMW c50, c41, VAG c46, c64, c74) and found that letting the tool make checksums on writing always resulted in a stuck process, regardless of using the power supply that came with the tool.
Another user faced the same issue and resolved it by writing via OBD, which worked successfully.
Conclusion:
If you encounter a similar issue, consider adjusting the voltage, checking for file errors, and exploring alternative writing methods such as OBD.
