Autotuner Simos 19.6 Security Gateway Detected Solution

Problem:

Trying to read and write Simos 19.6 ECU using Autotuner tool.
It said Secure Gateway detected.
Can I write without problem?

Solution:

Sfd1 is ok.
Sfd2 is a problem.
No need to unlock SFD1 with Autotuner on these.

Also check your voltage.
We work at a minimum of 13.5v on this ECU.
