On-board diagnostics also known as OBD, is a term used in Automative industries. This term refers to the facility available in most of the cars using which owner or the technician can come to know the actual part to which the problem is related. This function also allows the user to determine the health condition of the vehicle using data from the internal on-board computer fit in the vehicle. If there is any emission related issue, OBD scanner will detect it and will also let you know the specific area that needs repair. Two types of OBDs have been introduced yet. The first one (OBD1) is related to the emissions from the car engine while the second one (OBD2) is the improved version of OBD1. The second OBD system is more efficient than the first one but is available only in the latest vehicles.
The major reason for introducing OBD1 system is to control the carbon emissions from the vehicles. An increasing number of vehicles on the roads is creating severe pollution problems. Therefore, state authorities decided to implement a system by which a car producing more emissions that a safe limit will not be allowed to come on the road. However, this system could not make a complete success. Still this system helps the technicians to understand the actual problem in the vehicle and it becomes easier for them to target the right instrument while repairing the vehicle.
A beep sounds when you connect OBD1 sensor to the car’s on-board computer. If red light appears on the board, it indicates that emissions are crossing the safe limit and repair work is needed by the vehicle. A few more actions will ultimately reveal the part that needs to be replaced or repaired according to its circumstances.
There are some features that are associated with a particular model of OBD sensor. However, some of the general features of the sensor include:
No battery requirement – the device needs some power to operate. However, no additional batteries are required for the operation. A cable is provided with the instrument that can be connected to the on-board computer. This cable draws the necessary power from the board and switches on the sensor.
Safety – Built-in safety instruments are there in the sensor box. These instruments ensure that no electric shock may occur in the system during the problem diagnosis.
The size – size of the sensor is small making the instrument handy. You can keep the instrument in the dashboard while travelling. You may need the instrument in case a problem occurs in the car’s engine.
Built-in display unit – the built-in display unit enable you to use the instrument wherever you want. You do not have to depend on a separate computer or a display device to use OBD1 sensor.
Never tend to use the instrument if you do not know how to operate it. It may harm the car’s on-board computer. A complete instruction manual is provided with the device. However, it would be better to let the technician handle the sensor to detect the problem.
