I think this has to be a procedural or software issue. I replaced the original battery when it died and afterwards ran through all the major electronic features of my 2013 ML350. Lights, radio, ABS, windows, cruise control, power seats, and remote locks all work perfectly. BUT … the power lift doesn’t function at all. The latch locks, unlocks, secures & releases perfectly, but the motor doesn’t activate. The tailgate lock button engages all the door locks, then beeps instead of initiating the motor. The close button just beeps. The manual handle sensor unlocks properly when touched by someone holding the fob, but the motor doesn’t initiate. All three fuses appear to be in perfect condition but I haven’t tested them for continuity. No error messages or warning lights show on the dash. Can anyone think of what I’m missing here???
