A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
Failure modes, effects, and diagnostic analysis (FMEDA) is a systematic analysis technique to obtain subsystem / device level failure rates, failure modes and diagnostic capability. The FMEDA technique considers: All components of a design, The functionality of each component, The failure modes of each component,
The iPhone 14 and iPhone 14 Plus have an identical design to the iPhone 13, although the US models do not have a physical SIM tray. The iPhone 14 and iPhone 14 Plus are available in six colors: Blue, Purple, Midnight, Starlight, Yellow, and Product Red. [26] Purple is a new color replacing Pink used on the iPhone 13 and iPhone 13 Mini. The ...
Even if the machine is running in the steady state, the rotational speed will vary around a steady-state mean value, and this variation depends on load and other factors. Since sound and vibration signals obtained from a rotating machine are strongly related to its rotational speed, it can be said that they are time-variant signals in nature.
The ELM327 abstracts the low-level protocol and presents a simple interface that can be called via a UART, typically by a hand-held diagnostic tool or a computer program connected by USB, RS-232, Bluetooth or Wi-Fi. [2] New applications include smartphones. [3] There are a large number of programs available that connect to the ELM327. [4] [5]
The scan tool is connected to the vehicle's data link connector (DLC) and, depending on the particular tool, may only read out diagnostic trouble codes or DTC's (this would be considered a "code reader") or may have more capabilities. Actual scan tools will display live data stream (inputs and outputs), have bi-directional controls (the ability ...
A diagnostic program (also known as a test mode) is an automatic computer program sequence that determines the operational status within the software, hardware, or any combination thereof in a component, a system, or a network of systems.
Automatic test equipment diagnostics is the part of an ATE test that determines the faulty components. ATE tests perform two basic functions. The first is to test whether or not the Device Under Test is working correctly. The second is when the DUT is not working correctly, to diagnose the reason.
