    Many sensors on modern cars multi-task and report to more than one computer. A sensor failure or inaccurate signal may be responsible for both lights or circuits being affected. In either case a scan tool will be required to diagnose the circuit further and figure out the source of the problem.

    I have the same issue. I was told that there was a wheel speed sensor for my abs. These are found behind the wheels. The problem is finding which one has malfunctioned.
