How to Read Kia OBD 1 Codes

This tutorial will work for the Kia Car Model: Optima-2001-2006 ,Sephia-1994-2006,Spectra-2001-2006 ,Sedona-2002-2006,Rio-2001-2006 ,Sportage-1996-2006 ,Mentor-1995-1997,Sportage-1995-1997.

Accessing trouble codes

  • Ensure ignition switched OFF.
  • Connect LED test lamp between terminals B and P Fig. 1 .
  • Bridge data link connector (DLC) terminals Q and S Fig. 1 .Bridge data link connector (DLC) terminals Q and S
  • Switch ignition ON.
  • Check that LED illuminates for 3 seconds.
  • If LED extinguishes: No faults are stored in memory.
  • Count MIL flashes. Note trouble codes. Compare with trouble code table.
  • Additional trouble codes will be flashed in sequence, commencing with the lowest trouble code number.
  • Trouble codes consist of one or two digits. For example: Oxygen sensor (O2S). Trouble code displayed: 15 Fig. 2.Trouble codes consist of one or two digits.
  • A long pause separates each trouble code.
  • The ECM fault memory can also be checked using suitable diagnostic equipment connected to the data link connector (DLC).

Erasing trouble codes

  • Switch ignition OFF.
  • Disconnect battery earth lead.

WARNING: Disconnecting the battery may erase memory from electronic units (e.g. radio).

  • Depress brake pedal for 2 seconds.
  • Reconnect battery earth lead.
