When I go over a medium size bump or turn sharply my engine service light, ABS and tire inflation lights come on. If I stop, turn it off and back on everything resets. There seems to be no problems, but the lights come on
very easily over a simple bump and stay on until the ignition is turned off.

 

Sounds like a loose connection somewhere. Might want to check that all fuses and relays are pushed in all the way. Maybe a wheel speed sensor has a loose connection or is going bad.
