Finding and repairing automotive electronics hardware errors
Car electronics works in difficult conditions: temperature fluctuations -30 to +120 degrees, or even more. In addition, high humidity, vibration and other physical injuries are taking place. Therefore, in a modern electronic device, which, although designed to be reliable, still has errors, and circuits are going out of order. Car electronics mainly consist of engine and gearbox control, braking system, steering system, synchronization modules, main brains, chassis controllers, bridge controllers and sensors, and the like. All this is usually called a car’s brain. Technically, this is not just a computer kit but a set of different modules. These modules are often interdependent and one deviation can turn off the entire chain.
Some of the more sophisticated and upgraded cars may include up to 100 different modules and switches.
Repair of car electronic components at the component level
The modern car consists of a complex system of units, the work of which depends entirely on the electronic control units (automatic transmission, engine management, air conditioning, comfort system, body electronics, braking system, etc.). They receive signals from different sensors and, based on the received information, control the entire system. The cost of control units is high, these units often require additional actions (prescribe VIN, adaptation and calibration). Usually these actions are paid separately. In most cases, after the computer or electronics device is repaired, just we install it back in place. Therefore, a qualitatively carried out repair of the computer is an ideal ratio of price and quality.
Many workshops offer replacement of blocks due to the lack of qualified staff and related equipment. The electronic control unit has a very complicated device, therefore it is impossible to repair it on its own. Repair of control units at the component level requires not only the availability of appropriate equipment (measuring instruments, stands, sensor signals simulators), but also specialized knowledge in the field of autoelectrics and electronics (analog and digital).
The cost and scope of the repair work of the computer depends on the complexity of dismantling and assembly / disassembly of the control unit, the complexity of the damage, the cost of spare parts for repairs.
Repair of the instrument panel
The instrument console (panel) combines in a single design a whole group of instruments, the indications of which are designed to provide control of the operation of the units of the car and traffic safety. Automotive information systems are now created on the basis of microprocessor technologies controlled by the factory-installed system support.
Modern machines are equipped with sufficiently functional and informative instrument consoles. However, the presence of a large number of components increases the likelihood of various malfunctions for various reasons, moreover, the country of the manufacturer and the authority of the brand of the machine in this case do not play a significant role.
Repair of control units for industrial machinery and trucks
Modern industrial and cargo machinery has many instruments on board, which are controlled by electronics. In this case, the electronic units are subjected to much more influence of negative factors (vibration, condensation). The cost of control units is high, these units often require additional actions (prescribe VIN, adaptation and calibration). Usually these actions are paid separately. In most cases, after the computer is repaired, just install it in place.
Delivery times of some ECUs reach several months. Repair of the unit takes much less time. For typical faults and blocks from the 1st hour, for others from the 1st week.
