Dash lights - Slip, ABS, 4Hi

Hi, yesterday morning I found three lights on my 2010 Tundra dash - Slip indicator and ABS on solid, 4Hi flashing. I believe this combination points to a specific malfuntion. I did find a Tundra Indicator Lights and Problem Description chart on this forum, not sure where, but it did not have this combination of lights. Any ideas? I appreciage it. I will not go to a Toyota dealer.

 

Mine is 2wd did same pulling camper around curves. Even at under speed limit. Found abs front passenger sensor was bad. Replaced both. Issue fixed. Could try do same or disconnect neg. Cable battery to reset. Get it scanned for anynfaults at ur local part store. Of all else take to dealer

 

Thanks for your help...Autozone said since check engine light isn’t on they wouldn’t find error codes, they tried, didn’t find any outstanding errors. Friend with better one tried, no codes. Tried disconnecting battery and no difference.
