Abs, Trac and brake lights on after bearing replaced
Hi, I have a 2012 Camry SE V6. The rear right bearing went bad so I replaced it. After replacing it, ABS, traction control, and brake lights all went on. Scanner shows it is coming from that bearing hub. It is not the type that can go on backwards. I checked the connection and it is connected tightly. I also reset the light but it never went off. Anyone have any ideas? Could it be that the bearing hub is defective?

What is the trouble code?
The ABS wheel sensor generates a sine wave signal. The computer looks for this signal after car startup at X mph, if no signal the code is set. If the car is moving at a specified mph, say 25, and there is break in sensor output for a fraction of a second, the code is sent.
The output signal can be checked with a oscilloscope. It might be possible to check the sensor with a VOM. Search the internet for testing ABS sensor output.
A cars computer system can be setup where an ABS failure can cause other trouble lights to come on. A number of lights being on may not mean multiple problems.

Thanks for your reply. The code that is coming up is for the right rear speed sensor . That is what is triggering all three lights. Thanks =toyomoho;106363]What is the trouble code?

If the code is as thought, the issue is as stated in the previous post. This being an interrupted signal or lack of signal. The loss of signal set the code.
ABS and Track light on would be normal as these systems are now off because there is a problem. The brake lights icon means there is a brake problem.
Fix the problem with the sensor signal and the lights should all extinguish.
