Initialization [08/2014 - 08/2015]

  1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ALL DOORS)) 
    WARNING:

    When a door window regulator assembly, power window regulator motor assembly, door glass or door glass run is reinstalled or replaced, the power window control system must be initialized. Functions such as the auto up and down, jam protection, remote control and key-off operation will not operate if initialization is not performed.

    NOTE:
    • When a power window regulator motor (front door window regulator assembly) is replaced, DTC B2313 is stored. Clear the DTC after initialization.
    • When performing initialization, do not perform any other procedures.
    • When performing initialization, use the power window switch of each door to initialize each door window.
    • If initialization is not completed properly, the LIN communication system may have a malfunction (See article. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2014 - ] ).
    • Make sure to park the vehicle and turn off all the electrical systems before performing initialization. Initialization will be canceled if the vehicle is driven during initialization.
    • Make sure not to hit, strike or vibrate the door window glass during initialization because the vehicle is learning the sliding resistance of the door window glass.
    • Make sure not to operate the power switch to ready on or off during initialization.

    When the auxiliary battery is replaced, it is not necessary to initialize the power window regulator motor assembly.
