SAE J1962 OBD II Automotive Diagnostic Wiring Harness
SAE J1962 OBD II automotive diagnostic wiring harness
Electrical Specifications:
• Voltage: DC 300V 5m ohm/10 ms
• Contact resistance: 3.0 ohm MAX
• 100% open, short, and mis-wire testing
SAE Standards Documents on OBD-II
J1708 - Defines a standard used for serial communications between ECUs on heavy duty vehicles and between computers and vehicles.
J1850 - Defines serial data protocol with two variants: 10.4 kbit/s (single wire, VPW) and 41.6 kbit/s (two wire, PWM).
J1939 - Defines data protocol for heavy duty commercial vehicles.
J1962 - Defines the physical connector used for the OBD-II interface.
J1978 - Defines minimal operating standards for OBD-II scan tools.
J1979 - Defines standards for diagnostic test modes.
J2012 - Defines standards for trouble codes and definitions.
J2178-1 - Defines standards for network message header formats and physical address assignments.
J2178-2 - Provides data parameter definitions.
J2178-3 - Defines standards for network message frame IDs for single byte headers.
J2178-4 - Defines standards for network messages with three byte headers.
J2284-3 - Defines 500 kbit/s CAN Physical and Data link layer.
J2411 - Describes the GMLAN (single-wire CAN) protocol used in newer GM vehicles.
J1962 Connector Specifications
The SAE J1962 specification provides for two standardized hardware interfaces: Type A and Type B. Both are female, 16-pin (2x8), D-shaped connectors with a groove between pin rows. Type B's groove is interrupted in the middle, preventing insertion of Type A male plugs into Type B female sockets while allowing Type B male plugs into Type A female sockets.
Type A connectors are used for 12V supply voltage vehicles, while Type B is used for 24V vehicles with blue marking on the front of the D-shaped area.
