Not familiar with your model but normally its located below

The diagnostic check connector should be on the bottom of the dash-right of steering column 16pin connector-jumper the two upper right terminal A to B

Count the flashes XX XXX X X XXX XX XXX equals to code 23

It flashed 1-2-1-2-1-2-7-3-8-39-43-43-43-44-44-44-1-2-1-2-1-2-21-21-34-39-39-39-43-43-43-44-44-44-1-2 andso on repeating. I got the 1-2 are set numbers. And 34-44-39-21 are all trouble codes. But the other numbers I don't know why they are in there. Where can I find out what these codes mean? Thank you for your time. I really appreciate it.
