The most common malfunctions in the electronic control unit of the car and how to avoid and maintain them

First: Malfunctions of the power unit in the computer:

– It causes a complete stop of the electronic control unit from working, and it is considered the most frequent because it is a power unit where it is connected to the control unit internally, and all the parts that are fed by voltage directly from the control unit such as sensors and one of the reasons for this malfunction is either due to a poor connection in a battery or a rise in electric charge From the generator to the battery, which may cause or lead to an electrical short circuit in the sensors feeders,

– In order to avoid such malfunctions, you must make sure that the battery is connected well, and do a periodic check on the charger 

As for the method of maintaining this fault, it is as follows: 

This malfunction occurs mostly in the diode, whose function is to protect the control unit from high current, and it also occurs in capacitors and connections, and the repair process is done by changing all the damaged parts and it is clear to the naked eye that these damages are mostly,

Second: Sensor circuit malfunctions: 

When there are problems or malfunctions in the sensor circuit, their effect on the car is always poor performance and inefficiency. 

The most important reasons that lead to such malfunctions are mostly due to a breakdown in the sensors due to their life span or the conditions in which the control unit operates. 

In order to avoid this malfunction, care must always be taken to maintain the safety of electrical connections and reduce washing operations to avoid the problem of water leakage between the connections and wires, especially after the collapse of the waterproof rubber tires. 

The repair process is done by reconnecting the atmospheres cut from the circuits of the feeders to the sensors in the computer and changing the damaged ones .
