Ｍercedes C Class (W205) E Class (W213) S Class (W222) GLC (X253) GLE (W167) EQA (H243) EQB (X243) EQC (N293) 2016-2023 PHEV BMC Battery module Test Platform by Beyond OBD

Use our test platform to confirm the BMC battery module for your Mercedes is working, or whether you repaired it properly! This BMC module is often having file issues (contactor gets stuck due to limit of uses reached, solvable by file) as well as hardware problems (board fault). Our platform allows you to access it in diagnostic mode without having to install it on the car, or even on top of the battery! The same cable can be used to access the whole battery from the outside as well. Check our video for more info. Note: in some cases diagnostic may not enter into the BMS at the first attempt: just do it 3 times to make sure its not a bug of your diagnosis or simply the BMS was not ready at the time: relay clicks often so make sure you enter the module right after the relay clicked. Once you are in, there will not be disconnections. Warranty: 1 year (just applied to the interface, as wires are subject to wear and tear)
