Vehicle diagnostics is a procedure without which high-quality repairs cannot take place, so every service technician should have the diagnostic equipment and tools. They let you quickly determine the malfunction: for example, to identify the problems with the chassis, suspension, engine, transmission or electronic systems. Quick and accurate troubleshooting, subsequent repair – this is the quality service that owners of expensive machines lack so much.
Is It Really Necessary
Technical inspection is regularly carried out to reduce the risk of vehicle breakdowns. Why then do you need a machine diagnosis?
Full diagnostics is required when buying a used vehicle. Even if the former owner does not conceal possible shortcomings, absolute serviceability cannot be guaranteed. The older the vehicle, the more often it is recommended to closely monitor the operation of its details. The condition of modern machinery is checked using computer diagnostics. Thanks to the help of the Caterpillar engine diagnostic tool, you can find out how to repair the engine and what its cost will be.
The on-board control system collects information about the state of the parts in the control unit. It is not available to the driver. All data on malfunctions is stored in encrypted form and transmitted to a special scanner, connected separately. It can only be decrypted by a specialist who determines where the vehicle malfunctioned, where preventive measures should be taken.
Professional engine diagnostics is perhaps the most important element in checking vehicle condition. The smell of gasoline in the cabin, increased fuel consumption, reduced engine power, frequent overheating, uncharacteristic sounds during operation indicate the need for engine diagnostics are things to consider. But even if these factors are absent, it is worth checking the machine out. Indicators may be within normal limits, but close to boundary ones. Then it is necessary to carry out the preventive work recommended by the master, so as not to exceed the permissible norms.
When and How Often Should the Engine Be Diagnosed
Do not underestimate the effect of minor malfunctions in the engine operation – measures must be taken already at the stage of their appearance. If you do not pay attention, soon, you will have to repair the power unit. Repairing it is an expensive procedure. Let’s list the signs when it is necessary to conduct a motor diagnosis:
- Significantly increased fuel consumption. The type of fuel does not matter.
- It is often necessary to add a lot of oil.
- There are difficulties with shifting gears.
- The appearance of unusual sounds when starting the engine.
For diesel vehicles, it is necessary to diagnose engine operation once in every six months. Moreover, it is necessary to carry out special machine preparation for the winter and summer seasons. Professional auto mechanics advise doing the diagnosis of internal combustion engines not only if a malfunction is suspected but also regularly for prevention. This method can often prevent serious damage to the power unit.
The Main Stages of Engine Diagnostics
Motor diagnostics is a process that involves more than one step. However, you should not neglect each of the steps, since all of them are very important for understanding the situation. Here are these steps:
Control the level and quality of engine oil. If the level is insufficient, then, quite possibly, the motor has significant problems. Sometimes the malfunction is eliminated by replacing the seals, but more serious repairs also occur.
Check Mounting Pads
Engine mounts play a huge role. It dampens the vibration of the unit and helps to synchronize its work with the gearbox. Only serviceable fastenings can ensure the operation of the machine in nominal mode.
Check Exhaust System
Reliable engine operation is not possible without proper gas exhaust. If the integrity of the exhaust system is violated, the engine not only loses power but also significantly increases the concentration of harmful substances in the exhaust gases, so this stage is important from the point of environmental impact view.
Check Power System
The speed at which the engine starts depends on the quality of battery charging that is directly related to the generator condition. At the stage of diagnostics of the engine power supply system, it is necessary to check the pull-up degree and the condition of the generator drive belt. It is also important to check the ignition system.
Take proper care of your vehicle, and it will serve you for many years.
