OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections. Manufacturers also ...
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 ...
In 1994, the CTX-5000 became the first computed tomography explosive detection system certified by the US Federal Aviation Administration (FAA). The certification of the CTX-5000 followed nine years of development. During that time the FAA invested $90 million in explosives detection and nearly $8.6 million in the specific technology.
A range of rugged hand-held scan tools is available. Simple fault code readers/reset tools are mostly aimed at the consumer level. Professional hand-held scan tools may possess more advanced functions Access more advanced diagnostics; Set manufacturer- or vehicle-specific ECU parameters; Access and control other control units, such as air bag ...
Side-scan sonar imagery is also a commonly used tool to detect debris items and other obstructions on the seafloor that may be hazardous to shipping or to seafloor installations by the oil and gas industry. In addition, the status of pipelines and cables on the seafloor can be investigated using side-scan sonar.
Sensors commonly scan at a rate of 24 Hz. Depth measurements are derived from measurement of hydrostatic pressure , and salinity is measured from electrical conductivity . [ 1 ] Sensors are arranged inside a metal or resin housing, the material used for the housing determining the depth to which the CTD can be lowered.
Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 ( KWP2000 ) and the now obsolete ISO 15765 -3 (Diagnostic Communication over Controller Area Network (DoCAN) [ 2 ] ).
The Marine Electrical Engineer is a vital positions in the technical hierarchy of a ship and is constrained by their assigned work under the Chief Engineer's overview. [2] An ETO manages a key role in the Senior Management Team and reports directly to the Chief Engineer.
