Does ABS system store codes?
Hey guys,
My ABS light has been coming on and off occasionally and I'd like to plan a trip to the dealership to have it looked at. It happens usually after the car has been heat soaked. I hear a buzzing sound from the ABS motor area when I turn teh car on and the ABS light stays on. If I turn the car off and let it cool, the light will eventually go away. I know that the ABS system can be scanned with consult tools for diagnostic purposes when a fault is detected (similar to ECU scan) but what I am not sure about is if the system actually stores historical codes. Anybody know this info? Ideally, I'd bring teh car in, they'd scan it and even if the light is not on, they'd be able to pull the code from ABS system and hopefully fix the problem. Any ideas?

Very good question.
We know that OBDII stores codes related to emissions and other problems. Remember that ABS is part of the ABS TCS VDC computer. Its one computer. I do not know what the relationship is between OBDII and the ABS TCS VDC computer.

check your break pads, I had my ABS, SLIP, and VDC lights come on and when I checked my pads they were low as **** but once I replaced them the lights went off

The buzzing sounds coming from the ABS motor area suggest that the ABS system is just tired. I replaced my front and rear pads last year so that isn't it. I checked the brake fluid level the other day and it's right at the high mark. The rotors are on their way out but they still have a little life left in them. The new pads are a metallic/ceramic matrix pad so they're not brutal on the rotors but not as gentle as pure ceramics either. I think it's the ABS system. I haven't had the chance to scan the car yet. I'll swing by Autozone tomorrow AM and have them do a scan.
