Re: Another Intermittent ABS Light
A few years ago I had the ABS/Trac light on my '99. The leaking brake switch was replaced ... no effect. I inspected/cleaned all wheel sensors ... no effect. Couldn't tell any difference in general braking performance, but just to be on safe side I had the code read at dealership. $300+ later I had a new ABS brake control module to install beneath floorpan ..near drivers area. No problem afterwards ... for a few years.
Now the light is back on warm days. Cold or rainy days there is no light. I found some websites that covered this issue. (Now when I Google, I no longer find them.) Seems that there are printed board circuits in the module that overheat and distort ... and then overheat even more until they self destruct.
Someday I intend to open up the module and see if there is anything I can fix. Hate to pay out that $300+ again.
