If ur lights are both comming on u have a bad connection at the wheel my alero had a bad wheel bearing that actually caused so much heat and friction it burnt the connector at the hub assembly behind ur caliper. check the connection there uif it grinds while u drive or break change the wheel bearing all lights and grinding will stop.

SOURCE: antilock brake /trac off light
In those cars, the wheel speed sensor is integrated into the wheel bearings. When one of the sensors goes bad, you have to replace the entire wheel bearing. Also, when the sensor(s) go bad, it will cause the loss of anti-lock braking and disable the traction control system.
The only way to identify which wheel bearing it is, is to hook the car up to a scan tool capable of reading ABS codes. That said, the front ones are more notorious for going out than the rear ones.

This may be a simple fix, where the wheel jack or washer bottle is located in the back behind the panel, there should be connectors for the rear lights, it is possible that the plug has been dislodged, remove the panels and check the plug connections. Good luck.

it is from a bad wheel speed sensor.The abs, traction control and other systems use the sensor.the various codes are for various system failures.The root cause is the sensor.
