My ABS and Break light have been on for at least 5 or 6 years......Has anyone had any luck with ABS ECU repaired? I had someone offer to repair for $40? Thank you.

 

I have the abs light on and the flashing red exclamatiin mark in brackets flashing. So I removed it and opened it up. It looks like there maybe a few gold coloured very fine threads missing? Can someone tell me if there's ment to be any missing .
The thicker silver coloured wires look ok and connected. Any help would be greatlying appreciated .
