Fix for dim high beams
If your highbeams are weirdly dim, here's what fixed it for me.
I tried a new bulb and it was still dim. It seemed unlikely to be the problem anyway because a light would usually burn out or not burn out, not be dim. Then it occurred to me, I had used a bluetooth OBDII phone app (Carista) to turn off the daytime running lights. The DRLs are the same bulbs as the highbeams. So I had a theory. Maybe the app that turns off the daytime lights was a hack. Maybe those bulbs have a program in the car's computer: "Operate at level 5 when lights are off (DRL). Operate at level 0 when main headlights are on. When highbeams are on, operate at level 10." And maybe the hack instructed the computer: subtract 5 from highbeam bulb program in all circumstances. This would have both the effect of turning off the DRLs, and dimming the highbeams. So I got out my OBDII reader and phone app. But it no longer worked. I had used it to turn off the DRLs before, but now could not access the OBDII tool at all. I tried other OBDII readers, other phones, and other cars. No dice. The Carista app said try our Carista tool instead of a generic tool. So I ordered the Carista branded tool and it worked once again. Annoying, because they probably just updated their app to say "only recognize our branded tool." So fiiiinnalllly today I could access the settings again. I turned the DRLs back on. And BAM... the highbeams are bright again. |

Nope, still works fine for my chinese ebay brand elm 327 dongle quite easily, however I've had several situations like yours where it wouldn't connect like yours and fixed it by clearing cache etc etc. Also it's not a "hack", it's literally user preferences stored in the ECU, the same thing can be done by a dealer using techstream....

If the same thing can be done by the dealer, does that also dim your high beams?

I like to decide when my headlights are on or off, that's all.
