So my SLI and LTP lighting has been going on and off for the last month, DRIVING ME NUTS........... I played around with it yesterday and then it stayed on[ oh great] so..........I did some research and found to disconnect the height sensor[mine was the front driver side] and add a little oil or grease, Well that did, it made the connection and all is well ,for now................I didn't know that there are 4 sensors???? any way happy again
