Front Sam Replacement
When installing front SAM in Mercedes W204 up to 2010 model year, you need to make sure the parts dept includes “jumper” wire Part number A…
This harness needs to be installed prior to completing component install. You will need to jump from connector 6, pin #4 to connector 2, pin #12
More specifically Install electrical wiring harness for actuation of starter relay between connector 6I pin4 and connector 2I, pin 12 on front SAM control unit with fuse and relay module (N10/1) Model 204 with code 807 (model year 2007) Model 204 with code 808 (model year 2008) Model 204 with code 809 (model year 2009) The model codes can be verified in EPC using vin and observing DataCard
Hi Josep, Is this due to Hardware changes on the F-SAM?? I believe i have never stumbled across this. And there is a lot F-SAM replacements going on in the Greek region. Unless our dealerships actually supply this every single time a new F-SAM is ordered.
This information only applies to the C-Class models
Thanks Josep. I have a custumer that replaced the SAM module, now the car don’t start, no crank. Could he had install this incorrectly? Or is a programming, configuration error?
look up the front sam replacement in WIS for this model and see if it shows a modification, if you do not have WIS send me your vin, i will have a look., verify all relays were swapped over from original and are in the correct locations
Well, this sure saved me some time today. I am just finishing up a front SAM replacement and the darn thing wouldnt start. I searched the internet and this came to my rescue. Thank you for posting it!
what is the process of doing this? ive installed a used front sam everything is working as it should but the car doesnt want to start. Should I bridge those pins? When I put the old sam back it starts again and Ive checked the relay and all fuses are fine.
