Can a Car Still Be Driven After Being Submerged in Water?

[OLena]

If a car is submerged in water, it can only continue to be used after undergoing repairs. Here is an introduction to what happens when a car is submerged in water: 1. After a car is submerged in water, many of its electronic components will be damaged, rendering the car unable to function properly. 2. Important electronic components in the car include the ECU, TCU, and many sensors. Without these, the car cannot operate normally. 3. The ECU is the brain of the engine. It collects various data, processes it, and then controls the engine's operation through various actuators. Without the ECU, the engine cannot function properly. If the sensors are damaged, the ECU cannot collect the necessary data, and the engine will also fail to operate correctly. 4. The TCU is the computer for the automatic transmission. This component also needs to collect various data and then control the transmission's gear shifts through control mechanisms. Without the TCU, the transmission cannot shift gears properly, and the car cannot be driven normally. If a car is submerged in water, these sensors and computers will be damaged. The car can only be used normally after replacing these damaged electronic components.
