did the oil spill all over and run over the sensors and short them out, did you change tires, wheels, rims, put a spare on, run through deep water, mud, take your VX swimming, attempt the TOD disconnect mod, rotate tires, mess with lug nuts, brake job, blow a fuse, have any wire work done, etc...

basically pick your brain for anything...I mean ANYTHING...that could have been serviced, tampered, changed, messed with, new, water, mud, mods, etc that could have happened recently. Then make a list. From there we can start a process of elemination.

I only had a flashing check TOD light after I took my VX SWIMMING quite litterally with water/mud coming over the top of the hood and into the doors where the windows were down. It never died, but it took about 7 fluid changes before all the water was drained. After everything dried out the TOD light stopped flashing.
