Q&A

I have a 2001 Chevy S-10 Blazer ZR2. I replaced both front wheel bearings and have checked all the sensors from all 4 wheels. All seems secure and unbroken. I used a code scanner, scanned and received no codes. Cleared anyway, then the light when off for a second and reappeared. The only time the abs light went away was when I hit the control module with my fist and went for a test drive. The light reappeared the second I hit a bump. My conclusion is I have a bad abs module, but I have heard 2001 chevy s10's have had a nasty habit of having this abs problem. Anyone have any info on whether I am accurate or if I am missing something? I check all connection at the control unit as well.
