QUICK ANSWER FOR MERCEDES-BENZ OWNERS
Written by the YOUCANIC technicians in Towson, Maryland, from the UCAN-II Pro coverage database and our own shop work. Updated October 24, 2026.
A Mercedes-Benz has more control units than almost anything else on the road, and the parts store code reader sees exactly one of them. The tools below are what we use in our own shop in Maryland to reach every module on a Mercedes, run the service functions the dealer charges an hour of labor for, and get the car back on the road. Pick by what you need to do, then check the two adapter rules by model year.
Reads and clears engine codes from your phone and gives you a live gauge dashboard. It does not see ABS, SRS, transmission or body modules. Right if the only light you care about is the engine one.
Full system, bidirectional, lifetime free updates. Reads and clears every control unit, runs actuations and the Mercedes service functions: SBC, Airmatic, AdBlue, injector coding, transmission adaptation, SRS and ESP resets, TPMS. The tool to own if you keep a Mercedes running.
Same scanner, shipped both ways free, with a refundable deposit that comes back when the scanner does. For the one SBC reset, Airmatic calibration or SRS code you need done once.
On the tablet you pick the control unit, then the function category (Control Unit Adaptations, Active Test or Configuration on a Mercedes), then the routine. These are routines the coverage database lists for the E 211, S 221, C 204 and ML 164 generations, grouped by the job you are doing, with the SBC, Airmatic and AdBlue jobs from our own guides alongside them. Names are as they appear on the tablet, Mercedes component codes included. Coverage varies by chassis and year, so check yours before you order.

Two chassis pulled from the coverage database, with the control units the UCAN-II Pro lists on each. Every unit gets fault codes and live data, and the database shows active tests, control unit adaptations and configuration where they apply.
| Vehicle in the database | Control units | Examples of what it lists |
|---|---|---|
| S Class W223 (2021 on) | 169 | Engine electronics for every engine variant (ME1778, MRD1, MRD2, MRG1, MRG1 AMG V8, MRG3, MRG8), Transmission control (VGS2NAG3M, VGSNAG3), Electronic stability program (ESP223 and the AMG ESP232), Supplemental restraint system (ORC223), Instrument cluster (IC223), Control unit Drivetrain (CDCC07, CPC3, CPC3 AMG), Control unit Fuel pump (FSCM GEN6) and more |

The database holds 74 Mercedes class entries, from the W140 S Class, W202 C Class and W210 E Class through the W206, W214 and W223, the EQ models and the Maybach 240, and the adaptation lists for the older generations run through the same ESP, CDI, ETC, AAC, seat, door and headlamp modules in the table above.
SCN coding of a new control unit, key programming and anything else that needs a live connection to the Mercedes-Benz server are dealer and Xentry jobs, and no aftermarket scanner does them. Xentry is the right tool for those: a laptop, a multiplexer and a subscription. For diagnosis, live data, actuations and the service functions above, which is what most owners and independent shops actually do week to week, the UCAN-II Pro covers it at one price with no renewal fee. Functions vary by model and year, so check your car or email support@youcanic.com with your VIN and the function you need.
Yes. The UCAN-II Pro deactivates the SBC system for pad and rotor work and resets the counter behind the C249F and C2498 codes. The SBC guide walks through it.
Yes, for anything beyond engine codes. On 1996 to 2002 cars with the round socket under the hood, the 16 pin port only reaches the engine. SRS, ESP, transmission and the rest answer at the 38 pin socket.
The UCAN-II Pro plus the DoIP adapter. The W206 runs its diagnostics over Ethernet, and without the adapter most modules stay hidden.
No. Those need Mercedes server access through Xentry. The UCAN-II Pro does diagnosis, live data, actuations, adaptations and the service resets listed above.
Different job. Xentry is the factory system and does everything, at a factory price with a laptop, a multiplexer and a subscription. The UCAN-II Pro is a one price tablet with lifetime updates that does the work an owner or an independent shop does every week.
Use the coverage checker with your VIN or year, model and engine, or call 1-888-959-4265, Monday to Friday 9 AM to 4 PM Eastern, and a technician will tell you plainly. If it does not do what you need, we will say so. Every scanner also comes with 31 day returns, no questions asked.
