Diagnostics for lo or hi beam inoperative - would be easy if it were the multifunction switch or a relay ... 2011-2014 Edge MKX _also 2015__Low or High Beams inoperative.pdf

check for accident history, specifically front end damage. very common for ambient temp issues to crop up after that. the reset above will work for dual climate control systems, not sure about manual systems. ambient lighting is run through the hvac module strangely enough lol. but assuming that you have Sync/8" screen to go with, you should look into updating the software to revision 3.10, the best and final, which fixed the ambient lighting software issue. now if there is a hardware issue, that's another matter.

how old is the command start? any way to take it out of the equation? have heard such units start to do weird things as they age.

parts stores will still "PASS" it tho, lol. there are a lot of warnings that pop up when attempting to start the vehicle. may be code related or entirely normal, check the owner's manual. you can definitely pull codes and check to get a better idea.

good troubleshooting! battery and starter are good places to start, especially starter, which has been known to fail in high temp situations. do you hear the fuel pump prime when turning the ignition to ON? should not affect the starter, just curious.

Welcome and congrats!

may just need a PCM calibration update https://drive.google.com/file/d/18rPm9EX1weiU5A_zBZXc1jpJd3-vV2MX/view?usp=sharing

Extremely rare IME for the cam sensors to fail, but have seen it happen ONCE. There is a TSB on the phasers for early gen 1 vehicles, but not for 2010. You should have the later P/N phasers in there already. Not on the Edge, but if the battery was leaking acid at any point, it is a reasonable thing to inspect the wiring around/below the battery tray. Oddball things can pop codes.

yes, one on each bank. confusingly, ford also refers to the timing phasers as actuators lol. the electronic sensors are underneath the intake tubing, a little work to get to them, but not bad.

bulbfacts.com ... oems are halogens, i assume?

how much did you drive the vehicle in this time period? wonder if the pcm was relearning/just finished & set the code.

did you use a motorcraft booster? aftermarket boosters can result in a lot of problems. did you tightly reconnect the hose from the intake manifold to the booster? you can check codes yourself with an obd II adapter and forscan lite. it is possible that the throttle body is going bad, but you can only retrieve the code after the engine is shutoff and before it is restarted successfully. the code is a temporary type.

well, you replaced the battery. that likely caused the pcm to reset and relearn your driving style. new maf sensor could definitely have helped as well, but it would have to be pretty far gone to make that much of a difference. fingers crossed for continued improvement. EDIT: another stray thought that occurred to me is that you should keep an eye on fuses 21 (EVAP canister vent control solenoid, Powertrain Control Module (PCM)) and 32 (Brake Pedal Position (BPP) switch, Mass Air Flow/Intake Air Temperature, (MAF/IAT) sensor, EVAP canister purge valve, VCT solenoids, Heated oxygen sensors) in the underhood fuse box. i seem to remember one or two cases where replacing those actually made a difference. very rarely see fuses and relays go bad on this platform tho.
