I am a newbie to the forum and first off want to thank everyone for all the help along the way. I have encountered a problem that I can not find a post/solution to. My ABS light came on yesterday, I took it to a buddies shop yesterday to have it scanned and it came back that all three ABS sensors were bad?? He told me he thought it was probably a ground issue. I have checked all the sensors with a multimeter and they all seem good (checked them for OHMS and cont.) Has anyone heard of the ABS modules going out? Does anyone know the locations of the ground(s) for the ABS system? Thank you in advance. My truck is an 05 6.0 with 183,000, and bone stock except an EGR delete. I am having no issues with the speedo or the overdrive.
