Inspection Procedure

NOTE:
  • When the power window regulator motor assembly (for rear LH 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 rear LH 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 rear LH side).
  1. CHECK REMOTE UP / DOWN FUNCTION 
    1. Check that the remote up/down function using the power window regulator master switch assembly operates the power windows (See OPERATION CHECK  ).

      OK: Remote up/down function is normal  .

      NG: Go to step  4

      OK: Go to Next Step 

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

      Standard Resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Switch Condition Specified Condition
      6 (UP) - 1 (GND) Auto up or up position Below 1 Ω
      7 (DOWN) - 1 (GND) Auto down or down position Below 1 Ω

      NG: REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Rear LH side)  (See REMOVAL  )

      OK: Go to Next Step 

  3. CHECK HARNESS AND CONNECTOR (REAR LH SIDE SWITCH - REAR LH SIDE MOTOR AND BODY GROUND) 
    1. Disconnect the power window regulator motor assembly (for rear LH side) connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      K1-6 (UP) - K2-10 (UP) Always Below 1 Ω
      K1-7 (DOWN) - K2-7 (DOWN) Always Below 1 Ω
      K1-1 (GND) - Body ground Always Below 1 Ω
      K1-6 (UP) - Body ground Always 10 kΩ or higher
      K1-7 (DOWN) - Body ground Always 10 kΩ or higher
      K2-10 (UP) - Body ground Always 10 kΩ or higher
      K2-7 (DOWN) - Body ground Always 10 kΩ or higher

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

      OK: REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH side)  (See REMOVAL  )

  4. CHECK HARNESS AND CONNECTOR (REAR LH SIDE MOTOR - BATTERY AND BODY GROUND) 
    1. Disconnect the power window regulator motor assembly (for rear LH side) connector.
    2. Measure the resistance and voltage according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      K2-1 (GND) - Body ground Always Below 1 Ω

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

      OK: Go to Next Step 

  5. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - REAR RH SIDE MOTOR) 
    1. Disconnect the main body ECU (driver side junction block assembly) connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      D48-10 (LIN2) - K2-9 (LIN) Always Below 1 Ω
      D48-10 (LIN2) - Body ground Always 10 kΩ or higher
