Use the 32MB blue reprogramming card that was sent to your dealer October 2004. Download the latest Hi-Scan Pro reprogramming software for the 32MB (blue label) reprogramming card from the Kia Service Information System (KSIS). The "Downloads" page is accessed by first logging onto KSIS, then by clicking on the "Downloads" link located in KSIS News Center. Dealers can also order a CD (optional) by calling 866 KIA-TOOLS and ordering P/N 111321KM.

NOTE:
  • A fully charged battery is necessary before reprogramming can take place. DO NOT connect a battery charger to the vehicle during reprogramming. Make sure the blower motor is 'OFF' during programming.
  • All reprogramming must be done with the ignition key in the 'ON' position.
  • Be careful not to disconnect any cables connected to the vehicle or Hi-Scan Pro during the reprogramming procedure.
  • DO NOT start the engine during reprogramming.
  • DO NOT turn the ignition key 'OFF' or interrupt the power supply during reprogramming.
  • When the reprogramming is completed, turn the ignition key 'OFF' and wait 20 seconds before starting the engine.
  • ONLY use approved reprogramming software designated for the correct model, year and engine size. Failure to do so may create other drivability issues due to the use of the incorrect ECM/PCM calibration.
