Tell you the OBD-II interface has a improvement over OBD-I!

The OBD II interface, an advanced new standard over OBD I, was introduced in the mid 90s. This standard provides near complete engine control and also works well for monitoring parts of the chassis and accessory devices as well as provides a complete diagnostic control.

Pre OBD II connectors were usually lined under the hood or even the dashboard of the car while OBD-II is definitely placed inside the reach from the driver (ideally within 2 feet from the steering wheel).

Usage: The usages of OBD II are aplenty. A number of them are as follows:

(a) Troubleshooting:
OBD II signal diagnosis, under most cases, is done in response to the “Check Engine” light on the instrument cluster or perhaps in response to drivability problems reported with a user. The scan results from OBD II can pinpoint malfunctions to a particular devices, thereby saving substantial period of time and cost when compared to the traditional guess and repair (read trail-and-error) methods.

(b) Vehicle Health Check:
Fraxel treatments can also help by giving valuable information on the condition of a second hand car that you simply desire to buy.

(c) Engine tweaks:
While most of drivers prefer their vehicles to become dependable and economical; a lot of us turn to OBD II for your extra performance from their rides.

OBD II systems are sealed and do not allow chip replacements. However, OBD II supplies a real-time data acquisition system that’s helpful to technicians. Technicians can in fact reprogram the performance parameters of the OBD II system to support performance options.

Proprietary sensor readings:
Though not really a part of the OBD II standards, the diagnostic readouts utilized by the casino dealer technicians are also through OBD II connectors. This helps in reading information like ignition voltage, individual cylinder misfires, ABS brake conditions, etc.

There might be over 300 readings available depending on the vehicle manufacturer and model. Scanners are of different types. Some scanners just show the fundamental OBD II signals. Another scanners can handle showing the entire range of system codes which have been used.

Real-time information:
We have now seen many vehicles coming up with multiple information systems as a part of the instrumentation cluster. This feature continues to be possible because of OBD II that is able to relaying run-time information like current mileage, best mileage conditions, miles on available gas, temperature etc.

Car designs tend to be more computerized and more complicated now than ever. Information relating to your vehicle maintenance, performance tuning, diagnostics and repair, driver evaluation, etc. can be purchased on its on-board computer systems.
