Pin Number of OBD-II Auto Diagnostic Cable

1, The standard OBD-II male connector is with full 16pins. And the female obd2 connector is with 16 plugholes.

2, If there is no special requirement, Fiberall provide the obd2 diagnostic cable with standard 16pins or 16 plugholes.

3, Pin assignment is a very features for obd diagnostic cable and other obd-ii diagnostic tools. If the obdii cable or the diagnostic tool is with wrong pin assignment, it will not able to work with the vehicle.

4, Function of each pin of the obd conversion cable is defined by SAE-J1962. If there is no special requirement, supplier will make the obd2 cable under this standard. Different protocol will require different connection. For example:

(A), J1850 VPW protocol: the obd2 connector should have metallic contacts in pins 2,4,5 and 16, but not 10.

(B), J1850 PWM protocol: the connector should have metallic contacts in pins 2,4,5,10 and 16.

(C), ISO 9141-2 protocol: connector of the obd diagnostic cable should have metallic contacts in pins 4,5,7,15 and 16.

5, But there are some special vehicles in the market, they are not equipped with standard OBD-II protocols. So there are also some special obd-ii diagnostic cable order which does not need 16 pins direct connection.

6, As for customized obd cable order does not require 16 pins direct connection. There is no need to revised the 16 pins on the front side. Just need to connect the end of the pins or leave some pins not connected on the back side.
