1- LO1 Understand vehicle systems fault diagnosis criteria and techniques
Answer: A process of diagnosis implies detecting or finding a fault or problem. In particular, a root cause fault is described as a core problem that has the potential of resulting in other observable symptoms and abnormalities. It is worth pointing out that a root cause fault need not be directly linked to the observable symptoms. It can also relate to indirect observable symptoms. Fundamentally, the root cause detection is primarily associated with the relevant procedures involved in the correction of abnormal conditions. It is essential to understand that a “problem” or “fault” in a piece of equipment does not have to be as a consequence of the equipment’s complete failure or even involve particular hardware. For example, a problem can be described as either an off-spec product or non-optimal activity. A classic illustration of this situation is a process plant, where in which the failures of hardware may be attributed to non-optimal operation. However, problems in the process plant may as well be as a result of poor quality of the feedstock, poor controller tuning, poor selection of the operating targets, and low …show more content…
Therefore, the system must be compatible enough to identify those faults and then remove them from the system to a considerable level. It had been observed that systems are having a dynamic life style there are set procedures and systems which must be taken in view and should be considered compatible enough for future use. To ensure that the successive attitude and the smooth running of system are ensured the diagnosis of fault is done in set comprehensive manner. THz e diagnosis should be done in time effective and cost effective manner. At the same time, diagnosing the necessary vehicle systems should give the aid in diagnosing the
