    By the way, what do you mean by probe holes? I'm still learning as much as i can since I'm an older guy that's new to the industry, lol ... thanks

    Some people use a metal pointed probe to Pierce the wire insulation to check for power in the wire.
    Where the insulation is pierced, (probe holes) the wire will corrode when moisture gets inside the wire.

    If you replaced the harness that shouldn't be an issue for you. Check the connections of the harness, make sure the ends are tight.
    Could be a loose connection somewhere in your system.

    Could be the ABS module.
    Call a dealer most are helpful.

    Got it, thanks for clarifying that. So far it has not come back on. I'll recheck the connections. It hasn't seemed to cause any issues, it just bothers me when any light is on and I want it fixed to avoid having a big issue. Thanks again.

    Here's what the light looks like.. it came on again today. Might not be a big issue, but I'm gonna try some of your suggestions and see what happens. If worse comes to worse, I'll take it to the dealer. 20200212_115342.jpg
