I have a similar intermittent issue (whenever I turn my wheel full lock left), and it never throws codes. Pretty much everything lights up, to include the brake and 4wd lights from occasionally. But still no codes. I'm assuming it's one of the connectors is either loose, or clogged up, but I've just been too busy/lazy to pull it apart and check it all.did you check the code?
I checked for codes on my truck when the SLIP light came on and didn't have any codes.did you check the code?Abs/ slip light won't shut off. I had a bad front bearing and replaced it, topped of my brake fluid, still on. It shuts off maybe 5% of the time otherwise it's constantly on and the 4wd won't engage. Any suggestions are appreciated.
