[attachment=104335]Hi everybody

I have a mercedes CLA 180 which a minor crash and a dtc B220700 was stored in srs ecu. it could not cleared 
so finally we replaced the module and did the adaptations. dtc gone.

The car does not start. We checked fuel , ignition, battery etc.

There is this value in MED40 module

Inhibit engine after crash event : Inactive  and the specified value : Active

I am told that this value should be active for the car to start.  
We did online update and scn coding etc for med40 but this does not change and the car still does not start.

We have checked both Fuse boxes. Checked Prefuse Box. Check starter battery and normal battery. Checked the injector coils, checked the turbocharger. 

Car not starting

your help will very much appreciated

Thanking you in advance

The car in the picture is not a CLA!!!

Is the screenshot from your car? I do not think so - MED177 with OM278 is different car.

What faults do you have in your ECU? Check in actual values is SAM the voltage levels.

Or better post complete quick test of the car.

I believe you have to replace or repair the fuse block. do not remember the name off the top of head but it will pop a fuse and unable to start car after

will check the pyrofuse box

Checked Pyrofuses. All ok. Check other fuses. The car has power. There is spark and also fuel is coming when we turn the key. But not starting

because crash event stored in med40 ecu

pls check SCN coding & update software N3/10 first!

no need to do anything online! Just reset crash event inside med40 ecu using xentry or vediamo/monaco.
