Already replaced speed sensor at transmision and did not fix problem, how can I troubleshoot the AFT Left abs speed sensor harness. Need a schematic or diagram. I want to troubleshoot the instrument cluster too, need your help.

This can be a few things, a faulty speed sensor, short in the harness a bad ecm or a faulty ip. Best to have a pro check this to save you some money.
