that's what i'm saying. when i bought my car the cruise didn't work and the abs / TC lights were on. scanners wouldn't give me any info about the abs. i replaced the ecbm and scanned again and it reported left and right speed sensors. replaced both harnesses , cleared the codes , lights went out and cruise control started working. i don't know exactly what fixed it , but i assumed it had to be connected to one of those replaced parts .
