OBD2 Extension cable OBD II OBD2 16 Pin Splitter T Splitter OBD Cable
OBD2 Extension cable OBD II OBD2 16 Pin Splitter T Splitter is also an improvement over OBD-II in both capability and standardization. This Cable OBDII Connector standard specifies the type of diagnostic connector and its pinout, the electrical signaling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. There is also a pin in the connector that provides power for the scan tool from the vehicle battery, which eliminates the need to connect a scan tool to a power source separately.
In Cable Information of OBD2 Connector :
It also has a Female OBD-II connector on a car Female OBD Connector connector pinout – front view The OBDII specification provides for a standardized hardware interface—the female 16-pin (2×8) J1962 connector. Unlike the OBD-I connector, which was sometimes found, under the hood of the vehicle, the OBD-II connector is required to be within 2 feet (0.61 m) of the steering wheel.
SAE J1962 defines the pinout of the connector as:
The amount of diagnostic information available via T-Splitter OBD-II Male to 2 OBD-II Female Cable OBDII has varied widely since its introduction in the early 1980s versions of on-board vehicle computers.
That is your car telling you there is an issue. If you visit a mechanic, he will use an OBD2 scanner to diagnose the issue.
To do so, he will connect the OBD reader to the OBD2 16-pin connector near the steering wheel.
This lets him read OBD codes aka Diagnostic Trouble Codes (DTCs) to review and troubleshoot the issue.
Features of OBD2 Extension cable:
It is also a Brand new and high-quality OBD-II cable.
For connecting your diagnostic interface and your vehicle with OBD-II compliant.
Length: About 200cm.
OBD-II Plug: 16-pin male to the car.
Mostly Used for diagnostic T-Splitter OBD-II Male to 2 OBD-II Female Cable Engine Company Vehicles.
Cable core: 8 Core.
