Trac Flashing with ABS solid On
Folks my 99 RX with traction option is giving the indication mentioned in the title.
It happened a few days ago after I inflated all the wheels (35psi) all around. On next start they went away. Now I am on the road, away from my trusty manuals and the lights are on again. Flashing yellow/orange is very annoying at night.
Any suggestions, how I can narrow down which wheel/sensor. There is no CEL so the OBDII reader would not work.

If you want to save the diagnosing till you get home and can't clear the codes by disconnecting the battery.

Thank you.
Partial quotation/repro for non commercial use is OK.

@Hypervish, would the procedure posted to troubleshoot a speed sensor signal be still valid to look for a potential ABS system problem? As Salim stated, he has a ABS solid on. I would expect a VSS light be solid on if using the speed sensor troubleshooting.
If the procedure is valid, i learned something new for next time
It was very tedious to troubleshoot my ABS solid light when it occurred. I pulled and cleaned all sensors, wire brushed the sensor holes, and cleaned the tone rings with brake clean.

The flash and lit signal went off and stayed off till I was about 30 miles from home.
I noticed it came on when I moved off (normal gas/acc) from a stop light. So it is not the bad roads of Houston. They must be causing havoc on shocks if you live in that town.
No problems in normal driving, but then the environment never needed traction to kick-in.
Need to read your instructions and my service manual to figure out how to read the numbers. I hope I dont have to count number of flashes.

I was thinking unary count, glad the display will be decimal. Since it is not a hard fail, I may have to live with a visual.
And thank you again ,,, the description you provided was not in Vol2.
