CHECK ALTERNATOR OUTPUT IT SHOULD BE 13.5 TO 14.5 VOLTS WITH ENGINE RUNNING.IF VOLTAGE LOWER 12 VOLTS THAT WILL CAUSE BRAKE AND ANTI LOCK BRAKE LIGHTS TO COME ON BECAUSE THAT NOT ENOUGH POWER FOR ABS BRAKES OPERATION.IF ALTERNATOR GOOD.BRAKE AND ABS LIGHTS ON ALSO MEANS LOW BRAKE FLUID LEVEL CHECK BRAKE FLUID LEVEL.ALSO. YOU HAVING BRAKE FAILURE.YOU NEED TO HAVE GARAGE OR DEALERSHIP CHECK BRAKES SYSTEM.BEFORE BRAKES COMPLETELY FAIL.
I think these lights are not related. The ABS light means the ABS is not working, and has nothing to do with the brakes working. You can have brakes and not have the ABS part working. I don't think a bad ABS would turn on the check engine light, but it may.
If you backup lights are not working as well, I would say check the fuse for the backup lights, if the fuse is good, see if you are getting power to that fuse. We had this problem and after weeks of searching and changing sensors, we found the backup light fuse was good, but not getting power. Ran a wire from that fuse to the cig. lighter fuse and all woprksf great.
