BlueDriver arrived this week!
Codes are for erratic ABS sensor on both left & right front and tone wheel. Both front unit bearings were replaced about one or two years ago... Pulled the front wheels off. Brakes & discs, then the unit bearing, so I could pull the sensors out.
Spun the axle around while looking in with a torch and found some grease on the tone wheels. No mud or other contamination. I was going to swap in some other sensors until I saw the grease. (The only problem with them is that they are OEM length JK sensors that have shorter leads than the ones in there now.) Wiped them off with some cotton buds & cleared the codes. Reassembled & a short drive later, all was ok.
Then again, that's what I said
last time!
We'll see.
