CyberNinja Posted August 20, 2023 Share Posted August 20, 2023 2011 Model Year C350CDI ESTATE Howdy, folks. No power outage, and all appliances that rely on electricity are running OK; the engine management light is on. The automobile has a removable towbar, and the Rear SAM unit has a special wiring harness for it. When I hook the caravan's electric wire into the car's 13-pin tow socket, the rear tail lights come on even if the engine is turned off (the key is taken out). My vehicle's backup lights activate when I turn on the engine. Please refer to the attached images for details on the scan I ran on my icarsoft MB v3. After a few days, or around 20 miles, the fault codes always come back after I clear them. I need some advice on what to do. Thanks Quote Link to comment Share on other sites More sharing options...

CyberNinja Posted August 20, 2023 Author Share Posted August 20, 2023 Howdy, y'all. Another i carsoft scan yielded yet another error number, in addition to the ones already reported. (for a picture, see below). To find relay 1 and circuit 15, I need the back-end SAM wiring schematic for a 2011 S204. https://i.postimg.cc/B6qw4Wcj/4.jpg Quote Link to comment Share on other sites More sharing options...
DreamWeaver Posted August 20, 2023 Share Posted August 20, 2023 The relays may be listed on a folded fuse diagram that may be found on the right end of the driver's dashboard (at least that's where the fuse diagram is in my W211 E320).

CyberNinja Posted August 20, 2023 Author Share Posted August 20, 2023 In such case, it's OK. I’ll have a look at it. Quote Link to comment Share on other sites More sharing options...
dave783 Posted August 20, 2023 Share Posted August 20, 2023 The ignition is active on circuit 15. Most often, a black wire. Quote Link to comment Share on other sites More sharing options...
CyberNinja Posted August 20, 2023 Author Share Posted August 20, 2023 I'll take a look when I can, perhaps over the weekend. Quote Link to comment Share on other sites More sharing options...
CyberNinja Posted August 20, 2023 Author Share Posted August 20, 2023 Update. I looked for a problem in the SAM wiring circuit 15 in the back, but I couldn't find one. I looked through the Westfalia's special wiring harness for towing and didn't find any problems. Next, I sprayed some WD-40 into the car's 13-pin socket and the towing plug for the caravan and made sure they both worked. When I finally got around to plugging the lead into the vehicle, the tail lights did not come on. The icarsoft scan revealed no problems with the vehicle's rear sam sensor. Nonetheless, a fresh defect showed up -: Right Rear Door Control Unit Malfunction (1) (DCU_RR) 990915. The State: The Past and the Present Additional Door Lock Actuator Motor Output Is Malfunctioning. There is either an open circuit or a short to the positive. The issue is the lock on the right rear door; all other doors open and close without a hitch. I put in around 20 miles yesterday over three trips with no EML activation in sight. Do you have any recommendations? I won't need the vehicle until the weekend, so I'll see whether the EML remains off until then. Quote Link to comment Share on other sites More sharing options...
