Inspection Procedure

NOTE:
  • The power window control system uses a multiplex communication system (LIN communication system). Inspect the communication function by following How to Proceed with Troubleshooting (See HOW TO PROCEED WITH TROUBLESHOOTING  ). Troubleshoot the power window control system after confirming that the communication system is functioning properly.
  • When the power window regulator motor assembly (for front passenger side) 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 switch assembly (for front passenger side) and holding it at the auto up position.
    2. Open the power window by fully pushing down the power window regulator switch assembly (for front passenger side).
  • When the ECU determines that the power window regulator motor assembly (for front passenger side) has a malfunction, DTC B2311 is set.
  1. READ VALUE USING TECHSTREAM (Main Body) 
    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 / Main Body / Data List.
    5. Read the Data List according to the display on the Techstream.

      Tester Display Test Part Control Range Diagnostic Note
      Power Window Power window OFF / UP / DOWN -

      OK: Front passenger side power window operates normally  .

      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.

      NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Front Passenger Side)  (See REMOVAL  )

      OK: REPLACE MAIN BODY ECU (DRIVER SIDE JUNCTION BLOCK ASSEMBLY)  (See MAIN BODY ECU )

  4. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Front Passenger Side) 
    1. Remove the power window regulator switch assembly (for front passenger side) (See REMOVAL  ).
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION
