louie ramirez if the monitors are not resetting right away its because something was repaired recently to do with the emissions and a trouble code was erased or cleared to remove the check engine light .now there should be no more check engine light on but you have monitors blinking on your scanner right ,now to turn those monitors off all you have to do is drive the vehicle and monitor with a scanner some cars clear right away and some can take up to 500 miles before the monitors clear ,don't panic its this a typical normal procedure just drive it should clear soon and good luck.

Have you fixed whatever caused the code to come on?
If not you will not be able to clear the code and pass emissions.
Two reasons -
1. If the problem has not been repaired the check engine light will come back on.
2. Clearing the codes usual means that the OBDII monitors will also be cleared. There will be a code stored for this until the monitors are complete. If they see this co they know what you are up do and you do not pass.
You may have to drive 300 to 500 miles or more,on multiple days and at different speeds and make sure to include long deaccelerations with your foot off the gas to set the EVAP. Most areas allow 1 monitor "not reset" and still give a full pass.Check your area for allowed number of monitors. If the check engine light stays out,the monitors will eventually reset,but on a older Hyundai it takes time.
Dynamic Stability Control....a derivitave of ABS / Traction control. The control unit that monitors the dynamics will most likely be sensing a difference in the measured wheel speeds. Possibly defective ABS sensor, wiring, ABS exciter ring, ABS module or steering angle sensor. Can also be triggered by wheel spin. Have a diagnostic scan done ( cost £30 - £50 approx at good local garage) to read the fault codes first. If you get a fault code relating to "ABS module pressure sensor" the module requires replacement (common issue). Used to be a £1400 job, but repair kit now available from dealer for £180 ish and 2 hours to fit.
The ABS light comes on when the ABS module
detects a fault in the ABS system. There are dozens of component
failures and open/shorts in wiring that will set the ABS light, ranging
from a faulty wheel speed sensor, open/short in wheel speed sensor
wiring harness, faulty hydraulic unit, fault electronic brake control
module(EBCM), faulty tone ring,etc. There isnt a relay or reset
procedure to turn the light off- it can only be turned off by repairing
the fault responsible for turning it on, and then using the factory scan
tool to erase the fault code and reset the light.
it is possible the majority of the faults to be repaired at home, the
fault codes can only br retreived with a diagnostic scanner with ABS
capability. This has to be done first in order to know where the problem
is to either repair or do further diagnostics to determine if it is a
faulty part or a wiring harness issue. If the problem is in the
hyrdaulic unit, this would need to be replaced by a shop as it will
require bleeding afterwards with a diagnostic scanner.
would advise spending the $50-70 to have the on-board computer read for
stored ABS fault codes. Considering that most sensors cost that much
themselves, you can quickly sink much more than a diagnostic fee into
replacing parts based on "what usually goes out" guesses
Hope this helped (remember comment and rated this).
If you have voltage from all of the speed sensors on the wheels, only then think about getting the ABS pump control repaired or replaced. It could be the reluctor.
I repair Volvo and Mercedes without issue so I think you could get the module repaired at a competent repair shop.
Took me 20 minutes to remove, repair and replace the module on the V70. Mercedes took a bit longer as the module was awkward to get to.
