I installed a new radio in my car over the weekend, and now my ABS light is flickering on and off...... I don't know what happened during the install, but this has never been a problem before.....
Besides the obvious of checking your wiring? Other than that, it may be coincidental. What year car? How many miles? I had a rear ABS sensor go bad, and that coincided soon after with a loose connection into the ECU which set off my ABS light.
