Ford OBD-II socket pinout (J1962 16 pin) and protocols by year of production

Ford/Mazda Interface Classic Hardware / Connections Basic ⏱ 10 min 13 steps

Signal layout of the 16-pin J1962 OBD-II diagnostic socket on Ford vehicles, plus a summary of the protocols used by year of production. Use it to check the wiring and to work out which line the module should answer on.

⚠ WarningPin 13 carries the FEPS signal (Flash EEPROM Program Signal) at +18V: that is above battery voltage and must only be used where it is genuinely called for.

Procedure

  1. Identify the socket: proprietary 16-pin OBD-2 J1962 connector, the diagnostic interface for all Ford models.
  2. Pin 2: J1850 PWM Bus+.
  3. Pin 3: LS CAN High - low speed CAN bus (125 Kb) or UBP.
  4. Pin 4: CGND - chassis ground.
  5. Pin 5: SGND - signal ground.
  6. Pin 6: HS CAN High - high speed CAN bus (500 Kb).
  7. Pin 7: K-LINE (ISO 9141-2 and ISO/DIS 14230-4).
  8. Pin 11: LS CAN Low - low speed CAN bus (125 Kb).
  9. Pin 16: +12V - battery feed.
  10. Pin 10: J1850 PWM Bus-.
  11. Pin 14: HS CAN Low - high speed CAN bus (500 Kb).
  12. Pin 13: FEPS - Flash EEPROM Program Signal, +18V.
  13. Check the protocol against the year: 1996-2004 ISO 9141; 1996-2007 UBP; 1996-2001 J1850-PWM only; 2002-2006 J1850-PWM or CAN; after 2006 CAN.
