O.K. I can't seem to find the exact same conditions in the archives so I will ask.

I am driving (not on the brakes at all) and the abs and brake light flash at me beeping three times and shut back off when done. It does this every 135 miles for the last 405 miles. I scanned the car with my Mac task master and get no codes. The abs is functioning (I know because I use it alot).

 

One of two things is happening. Either the esp system is kicking on due to an erronious sensor reading. May not necessary thor a code. Or you control module is failing. Check the ecm and tcm for faults. If the brake control moduel is failing there should be a fault for sporadic no communication there.

 

Thanks dank.

I found a tech article somewhere else stating that it is the control modual. The problem can start out intermittent and will get worse. The reason I can't pull a code is because the light isn't on. The only time it will throw a code for it is when the light stays on.
