Hello sorry for the delay, I lost power and internet for a few days due to a huge storm that hit here.
Are you able to count the number of blinks after the 3? The flashes should be a 1/4 of a second apart. Is it possible there is 1 flash and then 3 and then the steady flash after that. A code 31 would be Right Front Wheel speed sensor, so passenger side front. The listing starts with code 11 so there is no code 3. Does it repeat the flashes after two minutes? I'll post the code lists for you.
This is just the ABS light flashing, not any Traction control light as well, correct?

Hello, thank you so far!
I have come to tell you that I have solved the P0500 by replacing the right front abs wheel speed sensor and the problem solved. I have yet to replace the left front ABS wheel speed sensor to complete the speed sensor circuit.
How do I reset ABS ECU memory?

Okay cool, so it was a code 31, To clear the ABS codes without a scan tool, Ignition switch Off,
jumper to Tc to E1 with the Shorting pin removed, Key On, press the Brake pedal 8 times in 5 seconds. Recheck for any codes, Constant flashing means no codes. It doesn't say, but Id assume key Off, then pull the jumpers out and reinstall the Short Pin where it was, and that should be all.
Is your Speedometer working correctly now?

Your Speedometer is working correctly now? Yap For sure.
I have done that but it didn't work, I jumper E1 and Ts: it blink 3times and begin to blink faster, then I jumper E1 and TC, that was when I began to get Code 31 and 32 only even after replacing one side of abs sensor

Did you pull out the Short Pin jumper the first time you pulled the ABS code? I'm wondering if service info is incorrect with that. I don't remember the code retrieving section had that included. E1 to Ts is for pulling codes, the E1 to Tc is for erasing codes.

It wasn't in the Speed sensor circuit check, look back at the first code retrieving info on the first page. There was no Short Pin jumper taken out. This is the last code instructions, this was what gave the 3 and multiple flashes after.

Just try clearing the codes without reading them again.

Which terminal is the correct one for clearing codes E1 and TS or E1 and TC?

Tc and E1 to clear the codes, and the Brake pedal 8 times in 5 seconds.

Yep, thank you so far!

I have done that by jumper E1 and TC and immediately the ABS light began to blink, I depressed the brake pedal and it off, when I released the pedal, it came back and only return Code32 while code 31 is gone. Now if you jack up the right front tire and engage gear and spin the tire, the combo meter will work, but if you jack the left front tire and engage gear and spin the tire, the combo meter will not work. I replaced another used ABS sensor and first wanted to clear it, it wipe and return back. So, I will look for another tone ring and shaft head to retest it.

That's unfortunate I thought we had it figured out. Can you pull the sensor out and see into the trigger/tone wheel and see if there's any dirt or corrosion in there, rust can cause this as well. With you working on things and moving them around, I wouldn'tt be surprised if there was rust stuck to the end of the sensor or in the tone wheel. The tone wheel is an exterior one on this right? It's not inside the wheel bearing.

I replaced left front abs wheel speed sensor and I reset the ABS module, then engage gear and spin the tire, the combometer started working. So that's the end.

Strange, maybe it was the left front that was bad to begin with, and the module was comparing the two. But glad it's fixed.
