Driver Side Power Window does not Operate with Power Window Master Switch: Procedure

  1. CHECK LIN COMMUNICATION SYSTEM 
    1. Check for LIN communication system DTCs related to the power window control system.

      OK

      LIN communication system DTCs are not output.

    NG → See step   10 

    OK: Go to next step 

  2. CHECK FOR DTC (B2312) 
    1. Check if DTC B2312 is output.

      OK

      DTC B2312 is not output.

    NG → See step   9 

    OK: Go to next step 

  3. READ VALUE USING TECHSTREAM (FRONT POWER WINDOW REGULATOR MOTOR LH) 
    1. Use the Data List to check if the power window regulator motor is functioning properly.
      D-DOOR MOTOR:

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      D Door P/W Up SW Driver side power window MANUAL UP switch signal/ON or OFF ON: Driver side power window manual UP switch on master switch operated
      OFF: Driver side power window switch on master switch not operated      		 -
      D Door P/W Down SW Driver side power window MANUAL DOWN switch signal/ON or OFF ON: Driver side power window manual DOWN switch on master switch operated
      OFF: Driver side power window switch on master switch not operated      		 -

      OK

      Techstream display changes normally when master switch is operated.

    OK → See step   7 

    NG: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH - FRONT MULTIPLEX NETWORK DOOR ECU LH) 
    1. Disconnect the P10 ECU connector.

    2. Disconnect the N13 switch connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection Condition Specified Condition
      P10-27 (SGND) - N13-12 (GND) Always Below 1 Ω
      P10-26 (CPBJ) - N13-11 (B) Always Below 1 Ω
      P10-27 (SGND) or N13-12 (GND) - Body ground Always 10 kΩ or higher
      P10-26 (CPBJ) or N13-11 (B) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  5. CHECK HARNESS AND CONNECTOR (FRONT MULTIPLEX NETWORK DOOR ECU LH - FRONT POWER WINDOW REGULATOR MOTOR LH) 
    1. Disconnect the N10 ECU connector.
      Fig 2: Identifying N10 ECU Connector & N11 Motor Connector

    2. Disconnect the N11 motor connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection Condition Specified Condition
      N10-5 (BDRJ) - N11-2 (B) Always Below 1 Ω
      N10-2 (PWE) - N11-1 (E) Always Below 1 Ω
      N10-5 (BDRJ) or N11-2 (B) - Body ground Always 10 kΩ or higher
      N10-2 (PWE) or N11-1 (E) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  6. CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTETR SWITCH - FRONT POWER WINDOW REGULATOR MOTOR LH) 
    1. Disconnect the N11 motor connector.
      Fig 3: Identifying N13 Switch Connector & N11 Motor Connector

    2. Disconnect the N13 switch connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection Condition Specified Condition
      N13-20 (UP) - N11-10 (UP1) Always Below 1 Ω
      N13-15 (DOWN) - N11-7 (DWN1) Always Below 1 Ω
      N13-20 (UP) or N11-10 (UP1) - Body ground Always 10 kΩ or higher
      N13-15 (DOWN) or N11-7 (DWN1) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  7. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH 
    Fig 4: Identifying Front Power Window Regulator Motor Assembly LH
    GTY288717Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    1. Remove the motor.
    2. Apply positive (+) battery voltage to the connector terminal 2.
      NOTE:
      • Do not apply positive (+) battery voltage to any terminals, except terminal 2, to avoid damaging the pulse sensor inside the motor.
      • Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly onto the door.
    3. Apply negative (-) battery voltage to the connector terminals 1 and 7 / 10.
    4. Check that the motor gear rotates smoothly as follows.

      OK

      Measurement Condition Specified Condition
      Battery positive (+) → 2
      Battery negative (-):
      1 (3 seconds or more) → 1 and 10 (within 1 second) → 1 (within 1 second) → 1 and 10      		 Motor gear rotates clockwise (UP)
      Battery positive (+) → 2
      Battery negative (-):
      1 (3 seconds or more) → 1 and 7 (within 1 second) → 1 (within 1 second) → 1 and 7      		 Motor gear rotates counterclockwise (DOWN)

    NG → See step   11 

    OK → See step   8
