There is a ground wire on the lower part of the left side core support that gets corroded. It is the ground for the ABS pump. Unbolt the wire, clean it and the place where it is bolted to, put a little bit of Dielectric grease on before re-bolting to the core support. Mine has done this for years, found the answer on youtube, it did cure the problem on my 2003 s-10 extended cab, basic.
