ATS function is engaged but not active

After a FLEX TO, you have an engine failure and you want to select MCT:

you set the throttle levers out of the FLEX/MCT detent (to TOGA or CLB detent) then back to FLEX/MCT position

Pressing the ENG. FIRE pb switch (on the ENG fire panel) causes the closure of:

fuel LP valve

ASYM amber message (FMA) means:

one thrust lever is set out of climb notch (both engines running)

MCT amber message (in the left part of the FMA) means:
