I am an old user and only recently returning to FTE after an extended absence. I have run across a problem with my ABS. I was able to scan the codes from the truck and found two codes B1266 and C1342. I was able to find information on the C1342 code but the B1266 from the Matco tools scan told me the ABS relay was below voltage. Unfortunately, Google and the search function on here yielded very little information. In fact, I received something that was a manufacturer reserved code and mixer door error.
Long story short, I am certain that the ABS module has failed. Does anyone have a way to identify the B1266 code? I haven't found an external relay that could be replaced so I am hoping that this is internal to the ABS Module.
