I have replaced my stock differential with a 3.33 gear set. Since my ABS light is on and the ABS is not working ... I think that one of my rear speed sensor cable is gone. I did a majic job on the differential but I screwed up things on the ABS cables. The worst is that I have no idea which side has gone bad. I have a 2006 Viper. The ABS unit is running on DRB III protocol. The tool cost $7000 so only dealers have them. If I replace the Speed sensor will the ABS light go off ? Will the ABS work right away ? Is there a majic home reset procedure ?
