Remove all vehicle seats, transmission decorative covers, carpets, etc., and thoroughly clean out the water inside the car. Replace the wiring harnesses of electronic components such as the audio system, air conditioning control panel, ABS module, etc. Drain water from the engine cylinders and intake manifold. Disassemble the transmission for cleaning, including the valve plate, etc. After cleaning, assess the extent of damage; severely affected engines or transmissions may need replacement. The vehicle's computer system includes the engine control unit (ECU), transmission control unit (TCU), airbag control unit, ABS control unit, etc. Additional steps include cleaning mud and debris from the chassis and addressing headlight components.
