    May need the abs system bleed, or you jack up a sensor while installing brakes, well need to pull codes and post up

    ABS light is on with mine as well. A conventional scanner wont work, must have something that will scan the BCM.

    I tried pulling codes, have nothing (which is good because before I started working on it, I had four PCM codes!!!!!!!!!!!!!) but none the less, no ABS codes. I'm fairly sure it's just a wiring issue ... I had both front brakes off (did calipers/pads/rotors), battery and alternator out while doing a plethora of work to my TA. At least my fingers are crossed it's a wire issue. I also went to replace my LR E-brake and it didn't correct my issue there, although it did make the lever seem tighter but I think I need new e-brake shoes.

    In MO it normally wouldn't pose a problem for an ABS light on but my car is on a "rebuilt" title from Oklahoma so they're going to nitpick everything since I have to get both state/emissions plus a structural inspection at the highway patrol. Thus far, I've had to put in a new steering rack, new tie rod ends, all new brakes all around (including the front calipers), new o2 sensor, new e-brake cable ... it's been a pain, but none the less, I love her still

    I had this problem for about a year no ABS or TCS, the lights would come on and then go off. I changed the wheel hubs rotors calipars this did not solve the problem.

    I took it to have the brake fluid changed and the mech ask if he could scan for any codes I told him to go ahead but he may not be able to find any. No codes came up so he check the harness with a volt meter and that's when he found the problem.

    Come to find out the harness from the right front speed sensor had two broken wires. The dealer had the harness on back order the cost was about 60.00. The mech fixed the broken wires and alll was good again.

    U can adjust it, it's just like a drum brake set up. There is the adjuster you just use a screwdriver and adjust to push the shoes out
