Hello,

My Hyundai Elantra J1 1500cc is displaying the yellow lights saying “Check Engine” as seen in the image. The light stays constantly on (not blinking) while driving.
As this car is pre-OBD, I’ve read that this car does display the Engine Codes by blinking the “check engine” light, but there is some diagnostic connector that I need to locate.

Can anyone help me locate it, and read the Engine Codes? Thanks.
