108k mileage 04 tsx AT(car complete stock). first start up only the triangle with (!) mark is on. after car move vsa light pop up and stay on.car drive fine with no problem(doesn't get stuck at certain speed) i research around and only found situation where both light stay on or goes on and off randomly randomly. is there any way to check the system or do i have to take it to a dealer to read the code. just from reading around, it seem like it could be the abs/speed sensor since it happen after moving. however the triangle with (!) is alway on. any input would be greatly appreciated

 

i also notice today driving another auto car(never drove a auto before) the tsx rpm drop to 1 asap once let go of gas pedal. is that normal?

 

check your ABS and speed sensors.

 

i did some more digging and found out to can jump pin 4 and 9 on the DLC and watch the abs light blink for code so im try to do that. but just incase do u know how i would check the abs/speed sensor? assuming using a dmm?
