For months my light flashed intermittently sometimes for an hour sometimes days. Thx to this forum I was able to narrow down the rear ride height sensor. I pulled it out removed the 4 screws fortunately mine was not in bad shape cleaned the top cover with alcohol and 1000 grit sand paper the main problem was 2 of the 3 contact springs were corroded in the seat. Cleaning the spring and seat fixed it. Not a complicated job at all and saved many $$$
