What are the symptoms of a faulty car computer board?
1 Answers
There are relatively many symptoms of a damaged car engine computer board, which is equivalent to the complete failure of the program controlling the engine. Some of the more common conditions include scrambled or dim display on the vehicle dashboard, unresponsive onboard computer screen, the vehicle being powered on but unable to start, or even the inability to open the car doors. Here is additional information: 1. Causes of computer board damage: The vehicle being soaked in water, leading to corrosion of the computer board causing open circuits, short circuits, or damage to component pins; and during vehicle charging, issues such as the charger voltage being set too high, reversed polarity, or the battery terminals loosening while the starter motor or engine is running, causing the alternator to directly power the computer board, resulting in the burning out of high-power voltage regulator diodes and other components. 2. Cars need to operate under various road and climate conditions: The working environment of the car computer is harsh, often enduring vibrations and changes in temperature and humidity. Additionally, the power supply voltage of the car computer fluctuates significantly and is frequently subjected to electromagnetic interference from inside and outside the vehicle. Therefore, car computers require high reliability and durability against environmental conditions.
