    12.  
    13. Check that the interval between blinks of the brake control warning light changes from 1 second to 0.25 seconds.
      NOTE
      The time needed to complete initialization of linear solenoid valve and calibration varies depending on auxiliary battery voltage.


      NOTE
      The brake control warning light blinks at 1 second intervals during initialization of linear solenoid valve and calibration and changes to the Test Mode display.

      If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.


      NOTE
      If normal pressure values are displayed, the IDs have been registered correctly.


      NOTE
      If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
