When installing aftermarket fenders on your JL Wrangler, you may get the Turn Signal Lights Out error message on your dash as well as the hyper flashing turn signals. This may happen after installing aftermarket fenders. Here are the links below for the bluetooth scan tool and the necessary cable needed for your JL Wrangler or your JT Gladiator. You will also need the Jscan app on your cell phone. It will cost about $20 to activate the Jscan app for your vin number. Please use caution before doing this project. We are not affiliated with any of the products mentioned in the video and use at your own risk. Good luck and feel free to ask any questions in the comment box.

UPDATE: This video will work properly with some fenders. But other fenders will require additional steps. If the video does not work then try this. Follow the same process outlined in the video. If it does not work, go back to the Jscan app and ACTIVATE the front turn lamps using the same procedure as the video. After that, we will need to clear the error codes in the body control module. Go to the LED LIGHTS SETTINGS page, the first option is to Restart all ecus. Click that. Then scroll down and select Body Control Module. You will see the dash quickly restart. Then turn the power off to the vehicle, open and close the door and wait for the vehicle to go to sleep. (Takes about 30 seconds for the dash to go dark). After the vehicle has gone to sleep, go ahead and restart the vehicle and hopefully the error messages are now gone. I have done this about 50 times and have been successful every time so far with the following brands. Fabtech, Westin, Rugged Ridge and Bushwacker. I hope this helps.
