What Is OBD or OBD2?

We have many OBD (On-Board Diagnostics) tools in stock. From 1996 most newer vehicles have standardized computer systems (also known as OBDII) that continually monitor the electronic sensors of engines and emission control systems, including the catalytic converter, while the vehicle is being driven to ensure they are working as designed.

OBD-II is an improvement over OBD-I in capability and standardization plus the OBD2 standard specifies the type of diagnostic connector, the electrical signaling protocols available and the messaging format. It even provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. There is a pin in the connector that provides power for the scan tool from the vehicle battery; therefore eliminating the need to connect a scan tool to a separate power source.

What's The Use Of OBD Car Scanners?

Environmental Protection Agencies are aiming to reduce emissions from cars and trucks, to do this they have been given the power to demand manufacturers build cars which meet increasingly stiff emissions standards. The manufacturers must further maintain the emission standards of the cars for the useful life of the vehicle. An OBD scanner provides a universal inspection and diagnosis method to be sure the car is performing to OEM standards. While some argue about the exact standards and methodology employed, the fact remains that there is a need to reduce vehicle emitted pollution levels in our cities, and we have to live with these requirements.

OBD-II signals are most often sought in response to a ‘Check Engine Light’ appearing on the dashboard of the vehicle. The data provided by an OBD-II car scanner can often pinpoint the specific component that has malfunctioned, saving considerable time and cost compared to guessing the issue and taking a risk by replacing or repairing without fully knowing the fault. Scanning OBD2 signals can also provide valuable information on the condition of a used car purchase so it is practical when going to inspect a used vehicle. There are even some OBDII readers that use Bluetooth to pair to your phone so you can view the information in the palm of your hand.
