Is possible to do offline with Vediamo and DTS Monaco (Runing for sdconnect c4 plus DOIP), also. And even if you were able to purchase, then you would need access to the online system for programming and SCN coding. Only shops with licensing through NASTF can purchase this part from dealer, here in the US. But you will not be able to purchase this part. I’d be inclined to swap test and/or replace the solenoid first, before throwing other parts at it.įinally, I highly recommend a brand new one……. I think the likelihood is the solenoid itself is bad or dirty. However, electrical connections exist between the TCM>conductor plate>solenoid… so there’s a possibility the conductor plate could be bad. Yes, the conductor plate usually suffers from a certain fault.

I suspect, it would only work during an ECO stop. That, I’m not sure of, whether it’ll run with the engine off vs. Now if it does have ECO, then there’s a electrical pump that runs. engine needs to be running for it to be operational. Solenoid filter(s) may need cleaning, or replacement.ĭoes the car have ECO start/stop… if not the only transmission pump is mechanical, e.g. The only leak would be past the o-rings on the molded connector and transmission body, which would just be a leak… no affect on electrical connection.Ġ748 The internal electrical check of component Y3/8y2 (K1 clutch control solenoid valve (VGS)) has failed. 9 variant integrated the TCM into the conductor plate and the connector is molded-in… so there’s nothing to leak into the vehicle harness or connector. The 722.9 doesn’t suffer from the same connector leaking issue as the 722.6. Don’t forget to put the solenoids back to original location.

If a new code pops up, then is likely the solenoid. Since you aren’t getting codes for the other solenoids… you could temporarily swap the “bad” one with a “like” colored solenoid (blue vs. I suspect the solenoid in question is: Y3/8y1 Working pressure control solenoid valve. I’d probably throw a solenoid at it before replacing the conductor plate… especially since it not a common fault, nor are there multiple faults present either. Obviously the solenoid can be bad, there’s a chance the conductor plate is/was bad or damaged in some way. Look at the following images showing I do have access to the laptop star(xentry) deal:Īssuming you’ve tried clearing and it comes right back.Ĭlick Tests, under the first picture, after you click the fault within the module. Then with Xentry offline you perform adaptations. If you get a new one from dealer or outfit selling virginized (used), then you’ll need someone with Xentry online to unlock and code the plate. Outfits that fix your original conductor plate won’t require coding or adaptation. Also with Xentry, you’ll have options to run guided tests, along with diag info. I’d do that first… before going down the rabbit hole. Some generic scanners cannot clear TCM codes. Usually the issue with the conductor plate is the speed sensors… if you have access to Star (Xentry), then pull codes with it and clear them. Resistance is 5.6 plus or minus 0.2 so good. Took it apart, tested the solenoids for clicking at 12v just the blue click the black make a different noise more like a buzzing. Put it all back and bam limp mode and the P0748 code is persistent.

Went through the flush and cleaning of the solenoids, found some dark matter, used a magnet. The user then will be able to generate an SCN Code using vehicle data as well as data from the replaced/flashed ECM.Car model and year: 2010 Mercedes W212 E350 722.9 Transmission

This will be possible by the user accessing a secured website utilizing a log-on and password unique to the user. SCN Codes will now be able to be generated by authorized dealership personnel via any computer with internet access or any NetStar Terminal. If your have trouble with transmission, there is a good chance that the problem is with you ME control unit and that SCN coding is needed to resolve the issue. It replaced the previous coding technique with a centralized and almost automated technique to prevent incorrect coding being selected when replacing a module.Ģ) Transmission gets stuck in 1 gear.
