Nothing was replaced following the previous DPS-CGK flight (for which we have seen the tech log).

As I posted on the day after the crash:

I'd have thought that (a) the EFC might well have been performing correctly anyway (in flight), given that the warning light responds to differences in either hydraulic pressure or pitot dynamic pressure, which were presumably detected by the EFC and (b) a ground test wouldn't necessarily be able to reproduce either of those conditions.

I'd be interested to know what procedure the AMM prescribes for diagnosing and rectifying this issue.
I haven't seen any subsequent posts re what the AMM says.
