Default Trouble codes and "SYS" light

Car: 92 auto coupe no selective ride control, i guess its a base model


I did some searching but im a rookie and dont know if all these issues are related. Today and yesterday i had the exact same problems im about to describe. I leave work and start my car. After idling for a minute "sys" flashes where the instant mpg normally is. The car started to feel like it was gonna die but didnt. (thats the only difference between today and yesterday, today car didnt want to die) Anyway the sys light flashes a few times, i didnt see security come on, but i also didnt know to look. I keep driving home, pondering the issue. Thinking it was fuel i decided to nail it and see if it sputtered. I left the light, laid in to it, it was wet so it spun, asr came on as normal. Then it went into 2nd(auto) and i noticed the service abs and service asr lights came on. I turned onto my road and decided to test the brakes. They seemed to work fine, so i took off again and asr didnt do anything. I stopped, turned the car off, opened the door, basically let it completely power down. Started it again, no lights, did same test, asr work, and brakes seemed fine. If i lay in to it and let it go in to 2nd the lights come back. I did not see sys any more until the next afternoon leaving work, which everything happened the same.

I did ab and ag the codes i got for ag are: 1. H13 4. H32 9. H35
For ab i got 32.

I know the 32 is egr after reading. However i dont understand the ag codes. My car is a 92 and my understanding was the modules read different for 4 and 9.

I believe you have two unrelated issues.

For the ARS and ABS lights, check your brake fluid level.
The system is very sensitive, and a lower than normal level can cause the lights.
I mention this, since you said they came on when you "nailed it". That would exaggerate a low level condition.

For the flashing SYS, do you have an aftermarket stereo system?
Flashing SYS indicates some sort of electrical issue.
The two most common causes are a low battery, or aftermarket stereo.

Not familier with the codes, but the "H" means it is a history code.
Whatever caused the code may no longer be present.

The two things I listed above are quick and easy to check, and will get you started.

12 isn't a trouble code. It is a placeholder that means the list is starting, empty or finished.

I just went to advance auto to get the battery checked. Before leaving i added some brake fluid. I pulled out, did my little test, same thing. On trip home however those lights did not come on. I just cheked under the hood, it did take eat some fluid, i had it filled damn near tothe top and it went down after driving. I did notice the feel got better too. I think that may be fixed! Thank you kind sir!

Now the problem is the c12. I cleared the 4 and 9 modules of their history codes. I believe in 4 thats due to the egr. That i see the ses light come on sometimes but itll go away after restart or driving for a bit. Im thinking and hoping the one in 9 was due to the brake fluid level being low
