Hi all DK friends
I have a situation here. Car is Mercedes E300 petrol 2018 w238
Auction buy. Do the diagnostic on the car, i enable the starting after crash on engine ecu and even did scn coding on engine ecu because starter motor did not actuate even after.
I check "drive authorizition " in all ecu"s and did a FBS 4 TEST along with the key test. All is ok.
I test starter motor terminal on actual values on engine ecu and is switchin on and off when i press brake pedal and start button.
Both of starter relay wires are going straight into ecu ( MED 17.2.2 )
If i activate starter motor relay manually in same time somebody is pressing starting button, car start for 4 seconds and switching off....
Ocassioanly i get this fault in engine ecu
P051200 START RELEASE FAULTY
I lock/unlock the car with remote key and this fault code sometimes goes off but still not starting
I put some pictures with positive relay box or whatever it is. On the side with the battery i have +12 but the other side i dont have.
There is a plug with 3 pins ( only 2 are used - gnd terminal 50 ) data pin is unused. Before i put termina 50 to positive starter motor was working when activating relay but no is onli clicking ( only starter motor coil ) i had to take big cable from this fuse/relay box and attach it to a + 12 positive and now is cranking again but still not starting
I think i must be burn it ... but problem is still at square 1
Any ideeas would be very appreciated!
