Inspection Procedure

NOTE:
  • When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized.
  • After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operations at least 5 times:
    1. Close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly and holding it in the auto up position.
    2. Open the power window by fully pushing down the switch.
  1. PERFORM ACTIVE TEST USING TECHSTREAM (APPLICABLE LOCATION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / (desired system) / Active Test.

      HINT:

      Perform the Active Test for the power window regulator motor assembly that has DTC B2311 stored in its ECU.

    5. Perform the Active Test according to the display on the Techstream.
      CAUTION: Be careful to avoid injuries as this test causes vehicle parts to move. During the Active Test, the jam protection function will not operate.
