  1. Adding BLIS to STX?

    I just made my own custom harness for the taillights that adds the missing Blis wires. I de-pinned the existing halogen taillight connector wires and added them to the new LED connector harness. The other end of the custom harness is added to the existing taillight harness next to the spare...
  2. ECU module programming guide using FDRS

    This is on a 2023 STX 101A. I sourced all the parts and made my own harnesses. HCM communicates through CAN Bus. I can see it and modify it via Forscan only. Fault codes are U2101 incompatible configuration and U2024 not programmed I believe. HCM does not show up on FDRS like I previously...
  3. ECU module programming guide using FDRS

    I did the swap myself like many DIYers here on this forum. It’s all pretty straight forward as far the hardware and electrical aspects is concerned. Just would like to have at least the APIM updated with the latest software so I can have the full screen CarPlay lol! I may have to reinstall the...

  6. LED projector upgrades

    Thanks for confirming. Writing the forscan values to HCM did not allow it to function properly or make any functional change. Have you done this with an unprogrammed module and experience the proper function of the headlight after just updating the forscan values?
  7. LED projector upgrades

    First of all, this thread is the most helpful to do this LED Projector swap so I’m very thankful to all that have contributed. I went from halogen to LED projector. Everything works except the HCM. Electrically everything is correct as I’m able to communicate with it via forscan. My issue is a...
