Vehicle Side Connector J1962 OBDII

J1939 Female to J1962 OBDII Female

J1939, OBD2, UDS, and J1708 for heavy-duty and light-duty vehicles. The family implements J1939 to RS232, J1939 to USB, J1939 to Bluetooth (including BLE), and wireless J1939 to WiFi (802.11b) interfaces, with support for Android and iOS devices. All devices support dual J1939, OBD2, UDS, and CAN networks and a single J1587/J1708 network.

The family was designed to meet the demanding bandwidth requirements of J1939 and the critical timing of J1708. The VNA devices provide internal buffers with up to 300 filters, largely reducing the overhead for the host. The adapters identify protocol errors, inter-character spacing, idle line detection, collision detection, and implements automatic retries.

OBD-II diagnostic connector[edit]

Female OBD-II connector on a car

Type A female connector

Type B female connector

The SAE J1962 specification provides for two standardized hardware interfaces, called type A and type B. Both are female, 16-pin (2x8), D-shaped connectors, and both have a groove between the two rows of pins, type B having a groove interrupted in the middle. This prohibits the insertion of a type A male plug while still allowing a type B male plug to be inserted into a type A female socket.

The type A connector is used for vehicles that use 12V supply voltage, whereas type B is used for 24V vehicles and it is required to mark the front of the D-shaped area in blue color.

SAE J1962 defines the pinout of the connector as:
