NOTE:
  • This procedure may be used with or without existing learned keys being present. If no existing keys are available, this procedure must be used.
  • A total of eight keys maybe be learned to a single vehicle.
  • This procedure will only learn the vehicle key information.
  • If the battery voltage is low, charge the battery before continuing with the procedure.

    7. NOTE:
    • At multiple times during the learn procedure, SPS will instruct you to turn the ignition to the run position. Make sure the vehicle is actually in the run mode before continuing on the SPS terminal. If the ignition is not in the run mode, the learn procedure will fail.
