It may not help but good to do, will force the HCMs to load the latest configuration, as well as there is nothing like a reboot to fix random issues. There is no calibration for headlamp level or aim, it is physically adjusted with the aiming adjusters, that is all there is as far as I know. Check codes after the reset of the HCMs, see if any have been set which might then give a clue to what the problem is.
The config in the CEM will never brick anything in another module. There are config items, the software in each module reads the broadcast config, it either accepts the values for the config items that it uses, or it does not accept them, in which case it will set a code for "invalid configuration".
No worries on the L/R detection, that is how the HCM module detects whether it is connected to a L or R headlamp hardware, one side puts voltage to a detection pin, and the other side lamp does not. You would expect them to be opposite.
Resetting the HCMs was the first thing I tried
I didn't confirm if the reset worked correctly but the headlight did shut off during the reset. I tried a 12v negative terminal disconnect for 30min as well as disconnecting and reconnecting the headlight connector with the battery unplugged.
The odd thing is that orbit doesn't (and hasn't ever) report any DTCs but my third party diagnostic tool does. Is it possible orbit isn't able to detect the failure?
