Abs light and traction stability control light keeps popping up.

IT first happened a year ago. Then it went away. Then it happened again then went away. Now it happend a few days ago. Came back today. And has went away in the middle of the day. And is back on when I was on my way home.

What do I do?

check the air pressure in your tires. low air will cause this

 

I had the same problem and tyre pressures appeared to be the problem. Since keeping an eye on my pressures the problem has not come back.

 

I appreciate both of your input!
I will be checking tire pressure today on my way to work.
Thanks again!

 

What DTC is logged in the module??
You can guess or ask the module what is wrong.

I have been getting the same thing, no DTCs logged. I made sure my tire pressures were correct (32 psi front/34 psi rear IAW tech data from Merchant Tire and Auto) and it made no difference. Seems like the code is completely random when it pops up.

 

How old is the battery in the car? Have it load tested and see if that is part of your problem.

 

There are no DTCs logged? There should be C codes in the ABS module.
You can't read C codes from the ECM, these are P codes. Are you reading the ABS module??
An ordinary scanner will read P codes and not C codes (or B codes).

What diagnostic device are you reading the ABS with??

The problem is, whether you go to the dealer, or buy the one device which reads C does, it costs several hundred $$$ !! That's why people are willing to do a lot of speculating.

 

Ouch!

 

I think you are looking a bad electrical conection. If the problem comes and goes.

 

I had the same problem but I got a P code eventually and it suggested a faulty front driver side wheel sensor. Replacing that cleared it completely. No message now for several months.
