      B2312 is not output A
      B2312 is output B

    B → See step   9 

    A: Go to next step 

  3. READ VALUE USING TECHSTREAM (DRIVER SIDE MOTOR) 
    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 operated
      OFF: Driver side power window 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 operated
      OFF: Driver side power window switch not operated      		 -

      OK

      Tester display changes normally when master switch is operated.

    NG → See step   4 

    OK → See step   11 

  4. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - DRIVER SIDE DOOR ECU) 
    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 (DRIVER SIDE DOOR ECU - DRIVER SIDE MOTOR) 
    1. Disconnect the N10 ECU 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 (DRIVER SIDE MOTOR - MASTER SWITCH) 
    1. Disconnect the N13 switch 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
      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 
    Fig 4: Inspecting Power Window Regulator Motor Assembly (For Front LH)
    GTY117180Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    1. Remove the motor. Refer to REMOVAL .
    2. Apply positive (+) battery voltage to the connector terminal 2(B).
      NOTE:
      • Do not apply positive (+) battery voltage to any terminals, except terminal 2 (B), 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 (E) and 7 (DWN1) / 10 (UP1).
    4. Check that the motor gear rotates smoothly as follows.

      OK

      Measurement Condition Specified Condition
      Battery positive (+) → 2 (B)
      Battery negative (-):
      1 (E) (3 seconds or more) → 1 (E) and 10 (UP1) (within 1 second) → 1 (E) (within 1 second) → 1 (E) and 10 (UP1)      		 Motor gear rotates clockwise (UP)
      Battery positive (+) → 2 (B)
      Battery negative (-):
      1 (E) (3 seconds or more) → 1 (E) and 7 (DWN1) (within 1 second) → 1 (E) (within 1 second) → 1 (E) and 7 (DWN1)      		 Motor gear rotates counterclockwise (DOWN)

    NG → See step   11 

    OK → See step   8 

  8. REPLACE MASTER SWITCH ASSEMBLY. Refer to  REMOVAL
