What is the difference between the built in scan tool by the car manufacturer into the On Board Diagnostic II tool in the commercial market?
Put simply, the difference between OBD-II generic versus OBD-II enhanced scan tools is that generic scan tools provide only emissions-based information on the vehicle. “When you get into enhanced (scan tools), you get into things other than engine, such as transmission, ABS, SRS (airbags), HVAC and more.
Why do we need OBD?
OBD stands for On-Board Diagnostic. It’s the standardized system that allows external electronics to interface with a car’s computer system. It has become more important as cars have become increasingly computerized, and software has become the key to fixing many problems and unlocking performance.
What does obd11 stand for?
On-Board Diagnostic II
OBD II is an acronym for On-Board Diagnostic II, the second generation of on-board self-diagnostic equipment requirements for light- and medium-duty California vehicles.
How do I know whether my vehicle is OBD-II compliant?
If the vehicle is not OBD2 compliant, you cannot use a generic OBD2 scan tool such as ElmScan to obtain diagnostic information from your vehicle. But my car has the 16-pin OBD connector, shouldn’t it be OBD2 compliant? No, not necessarily.
What’s the difference between an OBD and a UDS?
Generally, UDS and OBD are both diagnostic protocol, but they are actually not comparable. While UDS protocol is used to diagnose a fault in an off-board condition, i.e. when the car is at the service center, OBD is essentially an onboard diagnostic service.
What does OBD stand for in automotive category?

Where can I plug in an OBD-II scanner?
Just plug it into the OBD-II port of your car. CAN is one of the transport protocols of the OBD-II specification and should be supported by most OBD-II-Scanners The location of the port can be found using a Google (image) search.
What’s the difference between OBD and OBD II?
The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format. The OBD-II standard has been mandatory for all cars and light trucks sold in the United States since 1996.
What happens when OBD II detects a fault?
1. When OBD II detects a possible fault and keeps track of it in its storage. 2. OBD II waits until the next trip to see if the same fault occurs again. MIL will blink if problem is misfire. 3. In the next trip if the same fault occurs again, OBD II sets diagnostic trouble code (DTC) indicating the fault and turns on MIL.
When did the OBD II standard come into effect?
The OBD-II standard has been mandatory for all cars and light trucks sold in the United States since 1996. If your car supports OBD-II you’ll find the connector within 2 feet (0.61 m) of the steering wheel.
When does a car have to be OBD-II compliant?
United States legislation requires all cars and light trucks model year (MY) 1996 and newer to be OBD-II compliant. More information is available on the EPA’s website.
