Full-system Mercedes, Sprinter and Maybach scanner with active tests and the transmission adaption reset a 722.9 needs after valve body or solenoid work.
When a Mercedes with the 722.9 seven-speed or the older 722.6 five-speed starts flaring between gears, drops into limp mode, or bangs into Drive after a repair, the answer is almost always stored in the transmission control module, not in the engine computer a basic code reader talks to. This Launch Creader Elite V3.0 is the Mercedes-Benz, Sprinter and Maybach version of that tool. It scans every module it can reach on those vehicles, reads transmission codes and live data, runs the transmission adaption, and gives you bidirectional control for active tests. It also works as a full OBDII reader on any 1996-and-newer vehicle.
The 722.9 is controlled by a module built into the electrohydraulic unit inside the transmission. Mercedes service data lists separate solenoid valves on that unit for working pressure, for each clutch and brake (K1, K2, K3, B1, B2 and B3) and for the converter lockup clutch. The module learns how long each clutch takes to fill and stores those values so shifts stay smooth as the parts wear. After a valve body, solenoid or conductor plate repair, or a fluid change on a car that was shifting badly, the old learned values no longer match the hardware, and the shifts can feel worse than before the repair. Mercedes considered these adaptation values important enough to add a counter for gear adaptations at cold, warm and hot temperatures to its own diagnostic software in 2012. Clearing them and letting the module relearn is what the adaption function on this tool is for.
Scan all modules first, then open the transmission module and read the stored and pending codes. Watch live data such as current gear, fluid temperature and solenoid status on a road test, and use the active tests to command a component before you condemn it. On the 722.6, the febi bulletin on conductor plates explains how a failed N2 or N3 speed sensor or one of the six solenoids triggers limp-home and codes like P0715 and P0748 to P0753, which is exactly where live data saves you from replacing the wrong part. Our 722.6 common problems guide and the pressure control solenoid symptoms guide show what each fault looks like.
The tool covers Mercedes-Benz, Sprinter and Maybach for full-system diagnosis, and generic OBDII on all 1996 and newer vehicles. It uses CAN FD and DoIP, runs Android 8.1 on a 4-inch touchscreen and updates over WiFi with free lifetime updates in 12 languages. Launch states that available functions vary by model and year, so confirm your chassis and the specific reset you need before counting on it. If you also work on other brands, compare it with the Mercedes full-system scan tool with 722.9 TCM adaptation. All of our 722 parts are on the 722.6 and 722.9 collection page.
Other service resets come with it: ABS bleed, steering angle, battery registration, oil service, crankshaft sensor relearn, EPB, throttle relearn, TPMS, injector coding and suspension.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It reads the transmission control module on Mercedes-Benz, Sprinter and Maybach vehicles, with codes, live data and freeze frame. Launch notes that functions vary by model and year, so confirm your chassis.
Transmission adaption is one of its listed service functions. Run it after a valve body, solenoid or conductor plate repair, or a fluid service on a car that shifted poorly, then road test so the module relearns.
It covers Mercedes-Benz vehicles for full-system diagnosis, which includes 722.6 cars, and is especially useful for chasing conductor plate speed sensor and solenoid codes. Check your model and year against the coverage before buying.
No. Updates are over WiFi and listed as free for life.
Yes, as a generic OBDII scanner on any 1996 and newer vehicle. The full-system and bidirectional functions are for Mercedes-Benz, Sprinter and Maybach.
