That'* the ABS self-test you hear there.

You talking to me, or Mr. JL?

Both. All of us work the same on that one.

My 92 applies the brakes for traction control. It is exactly the same noise as when i lock up the wheels. Because the brake is being applied on that wheel, the differential (only powering the easiest wheel to spin) transfers the power over to the other wheel, where there is hopefully traction. I have never heard of retarding the timing, could that be for higher speeds when it would be dangerous for the brakes to be applied?

Its the second resort that the system is programed to do after it decides that the brakes just cant control it. I was starting on sheet ice one day and it just sat there spinning, the brake could not do anything to stop it. Then the engine took a wierd tone and no matter how hard I pushed the pedal it would not go above 2K. The car eventually got free, but it took a whole green light to do it.

That has happened only a few times that I remember, mostly brake application gets traction. I've never heard mine do the 14mph test.

I believe they switched antilock systems in 1994 and then again in 1996. So not all of them may do the self test at 14 mph.
