This is F30 chassis?
High voltage battery has safety terminal - check if its correctly locked, check also terminal on second battery (12v), this car has two battery (12v)

Have you correctly locked safety terminal?

Okay, one of 12v batt pyro has one more small plug, i think this one in trunk. Check if it's connected properly. Have you replaced them with new ones or are they regenerated?
///
It is a B73 * 2B plug, see attachment. On both pins, you must have a +12 power supply from the battery. Not to be confused with the * 1B plug coming from the ACSM driver!

But anyway i get crash massage from EME unit, According to my experience in Mercedes-benz there is an action in the original scanner xentrey that cancels the accident situation and then the contacts of the high voltage battery return to work.

Why don't you use ISTA and will tell you what EXACTLY you need to check. Instead of using some crap and guessing? AFAIK during serious crash EME generates an active short in high voltage system for all safety components to trip. It is possible that it still keeps this short status or has burned out when made it.
BTW you may need EOS tester or IMIB HV to clear SME fault.

In my experience, this error is generated during body repairs when someone disconnects the safety plug or when the additional plug from the pyrotechnic terminal is not connected or when the pyrotechnic terminal is regenerated (then the clamp does not close the circuit on the small plug going to the safety switch)
Anyway, as Node wrote, you should start with an ISTA diagnosis
