What should I do when the car ECU gets wet?

The box of the ECU itself already has waterproof glue. So no. It's good that the car can be used normally, but the working environment of the ECU itself is very bad. Water generally can't get into the ECU box.

ECU (Electronic Control Unit), also known as "driving computer", "vehicle computer", etc. In terms of use, it is a special microcomputer controller for automobiles. Like ordinary computers, it is composed of microprocessors (CPUs), memory (ROM, RAM), input-output interfaces (IO), analog-to-digital converters (AD), and large-scale integrated circuits such as shaping and driving.

In a simple sentence, "ECU is the brain of the car".

Generally, it will not be broken, and if it is generally dirty, do not continue to use it, remove it, and expose it to the sun. Or in the drying box, the temperature does not exceed 100 degrees, generally 80 degrees can be dried. It's a long time.

If you don't have it, just blow it with a hair dryer. It didn't work out very well.

There is generally a breathing hole on the ECU shell, which is rubber, removed and opened to bake. If there is no hole, you suspect that the water has entered, so you have to disassemble the shell and bake it.

In addition, most ECUs are waterproof, unless there is a problem with the waterproofing of the plug, and generally even if it is soaked in water, it will not be able to enter the water. So don't be nervous. Just dry it.

Hello! Landlord. The ECU on the car is basically useless when it gets wet.

But there is also a way, you can open the cover of the ECU and use alcohol to wipe the water or dirty areas on the circuit board! You can give it a try! The effect is okay, the little brother can try it.

Generally, there will be no water, unless the plug connection is burned out by water, it is recommended that the vehicle power supply is cut off in this case, and the relevant treatment is carried out after the vehicle is disconnected, and the ignition or live operation is strictly renewed.

The electronic control unit can be repaired after water ingress. After the water ingress into the ECU, it is very harmful to the car, and the water has a certain corrosiveness. If the ECU is soaked in water for too long, it will damage the relevant circuits or components on the car, and the circuit board is prone to rust.

If it is not repaired in time, there will be very big problems in the later stage, which will affect the normal use of the car. After the ECU is flooded, it is very harmful to the car, and the water has a certain corrosiveness. If the ECU is soaked in water for too long, it will damage the relevant circuits or components on the car, and the circuit board is easy to rust.

If it is not repaired in time, there will be very big problems in the later stage, which will affect the normal use of the car. In general, if the car is not immersed in water, the ECU will not enter the water. If it is a flooded car, the hidden dangers of the flooded car are mainly concentrated in small signal circuits, ECUs, dashboards and airbags.

This has little effect on high-current circuits. Once the car's ECU gets into the water or gets wet, it must be removed in the shortest possible time. Pure Bright Tank first wipes the surface moisture dry and then seals it with a plastic bag.

If necessary, use a vacuum empty machine to extract the internal moisture. Do not use baking equipment to bake the electronic control unit. This will cause surface moisture to enter the circuit board inside the ECU, which in severe cases can lead to permanent damage.

As soon as it is found that the electronic control unit of the car is submerged, in this case, it is necessary not to continue driving or restart the car. If the car restarts, it may cause a short circuit inside the ECU and affect the normal use of the car.

Generally speaking, if the car is not immersed in water, the ECU will not enter the water. If it is a soaking truck, the hidden dangers of the soaking car are mainly concentrated in small signal circuits, ECUs, dashboards, airbags, etc. , which has basically no effect on the destruction of high-current circuits.

Once the electronic control unit of the car is in the event of water or moisture, it must be removed in the shortest possible time. Wipe off the surface moisture first, then seal it with a plastic bag. If necessary, use a vacuum-empty machine to extract the internal moisture.

Do not use the baking device to bake the ECU. This will cause surface moisture to enter the circuit board inside the ECU, which can cause permanent damage in severe cases.

Once you notice that water has entered the ECU of your car, you must not continue driving or restart your car in this case. If the car restarts, it may cause a short circuit inside the ECU and affect the normal use of the car.

If the ECU is soaked in water for too long, the relevant circuits or components on the car will be damaged, and the circuit board is easy to rust, if it is not repaired in time, there will be a very big problem of stupidity in the later stage, which will affect the normal use of the car.

The ECU can be repaired after it has been flooded.

If the ECU is soaked in water for too long, the relevant circuits or originals on the car will be damaged, and the circuit board is very easy to rust, if it is not repaired in time, there will be a very big problem in the later stage, which will affect the normal use of the car.

Generally speaking, if the car is not soaked in water, the ECU will not enter the water, if it is a soaking car, the hidden dangers of the soaking car are mainly concentrated in the small signal circuit, ECU, instrument panel and airbag, etc., which basically have no effect on the high-current circuit.

Once the electronic control unit of the car enters the water or is damp, it must be removed in the shortest possible time, first of all, the surface of the water must be wiped dry, and then it needs to be closed with a plastic bag, if necessary, it is necessary to use a vacuum machine to pump out the internal moisture, do not use the baking equipment to bake the ECU, which will cause the moisture on the surface to enter the circuit board inside the ECU, which may cause permanent damage in serious cases.

Once it is found that the ECU of the car is flooded, in this case, you must not continue to drive or restart the car, if it is restarted, it may cause a short circuit in the ECU due to poor conduction, which will affect the normal use of the car.
