2016 Honda Mobilio "ABS and handbrake" warning indicator problems.

Hi, I have a 2016 Honda Mobilio. (I’m from the Philippines)
The ABS and Handbrake light suddenly came on while I was trying to do a u-turn to park.
I’ve checked the handbrake switch, brake fluid, replaced the front brake pads, inspected the rear brake shoes and reset the ABS system using the OBD II pin 4 and 9 trick. The light went away but after driving approximately 10 miles to work, it suddenly lit up again.
I reset the system once more and it went away. If it comes back up, what else can I check on my own before needing to go to a shop that has specialty tools? I tried looking for the blue 2-pin connector I saw on one of the videos to get error codes w/o a scanner but I could not find one. I saw a yellow 2-pin connector but both the driver and passenger side had them.
