BCM reprogram to fix hyper flash - dealer wants $124
So I replaced the 4 bulbs in the headlights for the turn signal with LED bulbs knowing that I would have to do the resistors, however, the more I thought about it the less i wanted to add 4 resistors to the mix.
I cam accross a thread on another forum about a service bullentin #1956334 that describes how dealerships can eliminate the voltage detection in the BCM so that LED lights will work correctly in rear and front turn signals.
I went to my local dealer and they wanted $124 bucks to reprogram the BCM...I cant see paying that much money just to eliminate the Hyper blink or AKA fast blink.
At this point I may just switch back to the standard bulbs...
