ABS, RSC, Advantrac, & 4x4 flashes 8 times

[fireball 440]

This just started today, to work and back 70 mile trip. I have my suspicion it's the LF wheel bearing / speed sensor. I replaced the right side a year ago for play in the bearing, but no warning lights. But I want to make sure.
What does the 4x4 High light flashing 8 times mean?

ABS light on.
RSC light on.
Check Advantrac on the display.
4x4 High flashes 8 times.

I didn't realized I was in the modified forum. This is a stock vehicle except oversized tires. If I don't get response here I will move it to the stock forum tomorrow, or a moderator can do it if he wants that would be fine.
