2. On-board diagnostics - Wikipedia

   en.wikipedia.org/wiki/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 federal emissions standards to detect failures that may increase the vehicle tailpipe emissions to more than 150% of the standard to which it was originally certified.

3. Ignition interlock device - Wikipedia

   en.wikipedia.org/wiki/Ignition_interlock_device

   An ignition interlock device or breath alcohol ignition interlock device ( IID or BAIID) is a breathalyzer for an individual's vehicle. It requires the driver to blow into a mouthpiece on the device before starting or continuing to operate the vehicle. If the resultant breath-alcohol concentration analyzed result is greater than the programmed ...

4. Traction control system - Wikipedia

   en.wikipedia.org/wiki/Traction_control_system

   The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential. A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.

5. Power-on self-test - Wikipedia

   en.wikipedia.org/wiki/Power-on_self-test

   Power-on self-test. A power-on self-test ( POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.

6. Passive infrared sensor - Wikipedia

   en.wikipedia.org/wiki/Passive_infrared_sensor

   A passive infrared sensor ( PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give ...

7. Crankshaft position sensor - Wikipedia

   en.wikipedia.org/wiki/Crankshaft_position_sensor

   Crankshaft position sensor. A crank sensor (CKP) [1] [2] [3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine ...
