Inoperative message after wheel bearing replacement
After replacing the wheel bearings, I got the error message below, I guess I got the "ABS" error message because I removed the brake caliper, sensor, and rotor. I am not sure about the "traction off" and "Inoperative. See Operator's manual" error. Anyone had got these after replacing your bearing or brake job? Thanks.
Had the car scanned and got these:
1. Powertrain System: produced primary trouble code:C0034 Right Front Wheel Speed Sensor
2. ABS Anti-Lock Brake System produced primary trouble code: 445800 The Signal Of Component ''L6/2 (Right Front Axle Rpm Sensor)'' Is Implausible.
I disconnected just the break pad wearing sensor and nothing else. I guess somehow I touched the speed sensor when removing the the caliper and rotor. Still not sure why the ESP is off. I thought I could save a few hundred bucks by replacing the wheel bearing myself but it's getting expensive when I broke something else. :-) By the way, it's not a very difficult job, I now know how to replace brake pads and rotors. Be careful when hanging the calipers and not damage the wires/sensors. The most difficult part was to remove the bearing races. The inner bearing race was pita to remove.
You most likely didn't torque the spindle nut correctly, I had the same issue on mine after replacing the front bearings. Any tiny amount of play in the rotor will throw the ABS, ESP error code.
You nailed it in the head. I tested the wheel again today and there was a lot of playing both up & down and side to side. I swear I tested it before I put the wheel back on. I tried it again, hand tie it and back off a bit. Spun the hub and tried again. Tested drive and all the CEL lights are gone. Thank you so much.
Now I got the "check brake pad wear" message because I tried to remove the wear sensor but I couldn't.
Fix one thing and break something else is always the case. Must have extra parts when trying to fix something.
