mikesmith2939 Posted September 9, 2017 Share Posted September 9, 2017 Are they HID's or normal bulbs? Also some models have static cornering lights as well, these only come on when turning the wheel left or right, could be one of those has failed.

Stoney871 Posted September 9, 2017 Share Posted September 9, 2017 If it's the same cause as on the Focus then it's a replacement unit that's needed.The light stops communicating with the car and drops to a default mode.Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...

mikesmith2939 Posted September 12, 2017 Share Posted September 12, 2017 I'm guessing you need Forscan or elmconfig to read the systems Quote Link to comment Share on other sites More sharing options...
