Scan Tool (automotive)
An automotive scan tool (scanner) is an electronic tool used to interface with, diagnose and, sometimes, reprogram vehicle control modules. There are many types from just as many manufacturers, one of the most familiar being the Snap-On Inc. "brick", or MT2500/MTG2500. Snap-On, Hella Gutmann Solutions, OTC/SPX, Xtool india, Autel, Launch, Vetronix/Bosch and a number of other companies produce various types of scan tools, from simple code readers to highly capable bi-directional computers with programming capabilities. 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 to make the controllers do things outside of normal operations) and may even be able to calibrate/program modules within c ...

Data Link Connector (automotive)
The data link connector (DLC) is the multi-pin diagnostic connection port for automobiles, trucks, and motorcycles used to interface a scan tool with the control modules of a given vehicle and access on-board diagnostics and live data streams. Prior to 1996, many OBD-I data link connectors were in the engine compartment, usually near the fuse block. Also, prior to 1996, there was no standardization for these connectors, and each manufacturer had its own shape with a unique pin arrangement. After 1996, many manufacturers retained their proprietary connectors in addition to the OBD-II interface, because OBD-II ports are only required to transmit emission-related codes and data. J1708 is a DLC used on heavy duty vehicles. OBD-II diagnostic connector The OBD-II DLC (post-1996 vehicles) is usually located under the instrument panel on the driver side, though there are several exceptions. The SAE J1962 specification provides for two standardized hardware interfaces, called ''type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pass Through Device (automotive)
A passthrough device is a device used in conjunction with a computer to reprogram vehicle control modules through the OBD-II/ CANbus port. Each manufacturer has their own type, but SAE International standardized the J-2534 universal requirements in 2004, requiring all manufacturers to allow vehicles sold in the United States of America and Europe to accept powertrain In a motor vehicle, the powertrain comprises the main components that generate engine power, power and deliver that power to the road surface, water, or air. This includes the internal combustion engine, engine, transmission (mechanics), trans ... reprogramming through specific universal parameters.

OBD-II PIDs
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 define additional PIDs specific to their vehicles. Though not mandated, many motorcycles also support OBD-II PIDs. In 1996, light duty vehicles (less than ) were the first to be mandated followed by medium duty vehicles () in 2005. They are both required to be accessed through a standardized data link connector defined by SAE J1962. Heavy duty vehicles (greater than ) made after 2010, for sale in the US are allowed to support OBD-II diagnostics through SAE standard J1939-13 (a round diagnostic connector) according to CARB in title 13 CCR 1971.1. Some heavy duty trucks in North America use the SAE J1962 OBD-II diagnostic connector that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ELM327
The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors. The original ELM327 was implemented on the PIC18F2480 microcontroller from Microchip Technology. While in business, ELM Electronics also sold other variants of the product, with slightly different part numbers, which implemented only a subset of the OBD protocols. In June 2020, ELM Electronics announced it was closing the business in June 2022. Uses 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. New applications include smartphones. There are a large number of programs available that connect to the ELM327. The function of such software may inclu ...

OBDuino
OBDuino is an open source trip computer design based on the Arduino platform. An OBDuino may be assembled and customised by an electronics hobbyist; it displays information such as instantaneous fuel economy (e.g. miles per gallon, L/100 km or kilometres per litre), engine tuning parameters etc. on an LCD. OBDuino utilises the On-Board Diagnostics interface found in most modern cars. Features * Most OBD-II PIDs or derived values may be displayed. Common values include ** Fuel: cost, used or remaining, wasted while idling, consumption, measured in mpg or l/100 km ** Engine: load, RPM ** Temperatures: coolant, air intake ** Vehicle speed ** Tank distance ** Remaining distance that can be travelled on the current tank of fuel ** Throttle position ** Battery voltage ** CAN status, for CAN protocol only, display TX and RX error * Displays instantaneous values, average, maximum and minimum values calculated per trip, per outing, or per tank of fuel * Menu system for configurin ...

On-board Diagnostics
On-board diagnostics (OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with United States vehicle emission standards, federal emissions standards to detect failures that may increase the vehicle tailpipe Air pollution, emissions to more than 150% of the standard to which it was originally certified. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of onboard vehicle computers. Early versions of OBD would simply illuminate a Tell-tale (automotive), tell-tale light if a problem was detected, but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data and Table of OBD-II Codes, diagnostic tro ...
