LED Lights / Indicators setup
First steps:
If you install LED lights - be it headlights, tail lights, indicators, etc., there is a high chance that you will get one of the following:
fast blinking indicators
flickering headlights
no headlights
no DRL
light malfunction warning on the dashboard
If any of these issues occur:
connect to your vehicle with JScan
go to Adaptations section
find LED Light settings or a similarly called group, OR, use the search (the green icon with a magnifying glass) and search for LED
identify settings called “LED <type of light> present ON/OFF” and enable it for every LED light you have
Note
If there is no setting for a given type (i.e. no LED Fog Lights for Wrangler JK) it means the vehicle software is not designed to accomodate for LED lights of a given type. You’ll have to install resistors (a.k.a. “anti-flicker harness”) or a CAN-compatible LED bulb.
Troubleshooting:
If the following steps didn’t solve the problem, you can try to:
search for adaptations with the word “diagnostic” or “DTC” and disable to disable the persistent trouble code (only in newer vehciles)
locate the HID (HIgh Intensity Discharge) Headlights Present, Quad Headlamp Present, and or Bi-Xenon Headlamp present and try if enabling any one or any combination of them eliminates the flickering. If not, you’ll need a harness or better quality headlamps
find an adaptation with the word “voltage” and ensure you set the DRL / LED headlamp volatage to 12-14V (most LEDs will not work at all on lower voltage settings and it’s not possible to adjust LED brightness with a lower voltage - this trick works only with traditional bulbs)
