another_clean_sheet Posted 5 hours ago Share Posted 5 hours ago My front left headlight is giving me the following problems. Problem with the adaptive headlight Failed Left Turn Signal No light may be directed vertically. Given the string of setbacks The TMS module was my first guess. I had to take this edge connection apart since it was so rusted. So I got an aftermarket part to put it back in its place. The error messages have not changed. Might the problem be with the bulb and the LED indication module? If you could assist, it would be great. Quote Link to comment Share on other sites More sharing options...
KWILB Posted 5 hours ago Share Posted 5 hours ago Was a TMS used for adaptive xenon, and were diagnostics employed for initialisation thereafter? Quote Link to comment Share on other sites More sharing options...
another_clean_sheet Posted 5 hours ago Author Share Posted 5 hours ago Hello, the provider assured me that the adaptive xenon unit I purchased will work with my vehicle. No, the diagnostic procedure is lacking. Would you be so kind as to tell me how to accomplish that? Can I do that step with my generic obd scan tool?

KWILB Posted 5 hours ago Share Posted 5 hours ago I first used ISTA when I first set it up a few months ago, but it depends on the scan tool you have. The otofix one I have does it. The procedure was walked me through by the test plan since it had a fault code, but I can't recall its specific name. Quote Link to comment Share on other sites More sharing options...
rab60bit88 Posted 5 hours ago Share Posted 5 hours ago My issue is with that. It's probably just my age, but KWILB, I have a terrible memory for where I saw stuff. Quote Link to comment Share on other sites More sharing options...
