Most car buyers are keen to land a vehicle with state of the art security features. A typical modern automobile in the showroom will have an intricate combination of mechanics, hydraulics and electronics working as a system. An automotive diagnostic service garage should have an assortment of tools that aid in the troubleshooting of everyday faults.
The control system has safety as its major priority, sometimes robbing the driver of his command to thwart accidental tendencies. For instance, automatic braking systems are designed to detect the commencement of slip at the road wheels. When a vehicle slips due to sudden application of brakes or because of a poor motoring surface, the driver will have a harder time regaining control at the wheel.
A perforated disc at the wheel works in conjunction with a magnetic sensor to monitor the speed of each tire. This generates an input signal for the electronic control unit which in turn regulates the braking effect. The overall effect is to redirect the flow of pressure in the hydraulic lines away from the slipping wheel and to the other slave cylinders starting with the fastest.
Conventional cars were more straightforward when it came to fault finding. Slow responses to inputs at the accelerator could be traced to rust deposits or blockages in the mechanical linkages that transmit motion to the carburetor. In a modern auto, a misbehaving accelerator could be anything from faulty air flow sensors, cylinder injectors or an interfacing problem with the on board microcontroller.
EFI systems will however outlive their predecessors due to the benefits they offer the owner. As a general observation, they result in more economical fuel use because motorists can cover more miles to the gallon unlike the carburetor models. The environment will be spared the pollution brought about by exhaust gases since these engines have a uniform combustion pattern.
Automatic gearbox manufacturers have also been testing computerized control in their systems for some time. They will keep track of the accelerator position and engine revolutions per minute to make decisions on the gear shift to be performed. An inexperienced driver may appreciate this kind of help but this would draw a negative reaction from seasoned motoring enthusiasts. Rally drivers also prefer manual mechanisms due to the nature of their driving.
The specialized diagnostics kit is turning out to be indispensable in a professional tool box. Most manufacturers sell these gadgets but they will only work with particular models. Technicians appreciate a software program that could transform ordinary personal computers into diagnosis tools. The biggest challenge has been realized in coming up with graphical representations of monitored parameters on the user interface.
Automotive diagnostic services outfits should strive to have technicians conversant with electronic systems on their payroll. Never ignore erratic behavior as it may trigger defects in the interfaced portions of the circuitry. Attempting repairs without the right tools can be both frustrating and destructive. A mis diagnosis could result in a needless purchase or put other elements at risk.
