The first step is to give a good visual inspection, if it's been in deep water check the fluid level and condition then check connectors for water intrusion and blow them out and add dielectric grease, check fuses and grounds. Andmost importantly retrieve codes with a scan tool, a code will be set even though the light is off. Good luck and let us know what progress you've made.
