Have you ever encountered a wrecked Mercedes that can't do "Enabling engine start after crash event"? No matter how many times I try, nothing works.
2017 E220d, front impact, airbags and seat belts deployed.
My MRD1 ECU and FCW213 Active Brake Assist show B1C3200.
The SRS module ORC213 shows several active errors for deployed airbags and seat belts. Clearing errors will obviously not fix active errors.

What should be the plan of action? I would like to start the engine before I start repairing the airbags and seat belts. Do you know how I could get a crash event from the ECU and is this really the cause of the failure to turn on the engine start?

From the screenshot it looks like the H relay for circuit 50 is burnt out, I'm just ordering it but that shouldn't cause the engine not to start or could it?

In order to reset crash signals from ME and ORC/SRS modules, you should first resolve the issues with the squibs restraint/bag squibs + the squib for battery.
To trick the system for a reset place 2.7R + Resistance on the squibs. Then restart/erase crash history in ORC/SRS first, then ME.
You may have to manually return the battery terminal cable, as this pops out in the event of a collision.
Let us know how it went. Write to us if you have any more questions.

Thanks karone, I was told that the OCR does not need to be "quiet" for engine start to be re-enabled. I have several bad squibs, such as in the instrument cluster, knees, steering, front left headliner, rear left headliner, and 4 seat belts. Do all these need resistors?

I think this model does not have a squib because the electricity comes from 12V.
 
Airbags can't deploy without squibs. And yes, you've tricked the computer into believing all the airbags are OK, so you need to place resistors on all the airbags that deployed.
And reset the crash data from the module.

I have everything ready, looks like a bad battery can ruin the diagnostics. Thanks everyone.
