Inspection Procedure

  1. CHECK AUTO UP/DOWN FUNCTION (REAR LH) 
    1. Check that the power window AUTO UP/DOWN function operates normally.
    1. NG: Go to step 2 
    2. OK: REPLACE POWER WINDOW REGULATOR SWITCH ASSY REAR (REAR LH) 
  2. INSPECT FUSE (RR DOOR LH) 
    1. Remove the RR DOOR LH fuse from the instrument panel J/B.
    2. Check the resistance.

      Standard: Below 1 Ω 

    1. NG: REPLACE FUSE 
    2. OK: Go to next step. 
  3. CHECK WIRE HARNESS (FOR POWER SOURCE OF REAR LH POWER WINDOW REGULATOR SWITCH ASSY) 
    1. Disconnect the P20 regulator switch connector.

    3. Check the voltage between the wire harness side connector and the body ground.

      Standard: 

      REGULATOR SWITCH CONNECTOR TERMINALS VOLTAGE

      Tester Connection Specified Condition
      P20-12 (BDR) - Body ground 10 to 14 V
    1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
    2. OK: Go to next step. 
  4. CHECK WIRE HARNESS (FOR GROUND OF REAR LH POWER WINDOW REGULATOR SWITCH ASSY) 
    1. Disconnect the P20 regulator switch connector.

    3. Check the resistance between the wire harness side connector and body ground.

      Standard: 

      REGULATOR SWITCH CONNECTOR TERMINALS RESISTANCE

      Tester Connection Specified Condition
      P20-7 (GND) - Body ground Below 1 Ω
    1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
    2. OK: Go to next step. 
  5. CHECK WIRE HARNESS (FOR WINDOW LOCK SWITCH OF REAR LH POWER WINDOW REGULATOR SWITCH ASSY) 
    1. Remove the regulator switch (the connector is connected).
    2. Turn the ignition switch ON.

      POWER WINDOW REGULATOR SWITCH CONNECTOR TERMINALS VOLTAGE

      Window Lock Switch Condition Tester Connection Specified Condition
      ON (Normal) P20-11 (PCT1) - P20-7 (GND) 10 to 14 V
      OFF (Lock) P20-11 (PCT1) - P20-7 (GND) Below 1 V
    1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
    2. OK: Go to next step. 
  6. CHECK WIRE HARNESS (POWER WINDOW REGULATOR SWITCH ASSY - POWER WINDOW REGULATOR MOTOR ASSY AND BODY GROUND) 
    1. Disconnect the P20 power window switch connector.
    2. Disconnect the P25 power window motor connector.

    4. Check the resistance of the wire harness side connectors.

      Standard: 

      POWER WINDOW REGULATOR SWITCH AND POWER WINDOW REGULATOR MOTOR TERMINALS RESISTANCE

      Tester Connection Specified Condition
      P20-1 (DN) - P25-2 (D) Below 1 Ω
      P20-6 (UP) - P25-1 (U)
      P20-1 (DN) - Body ground 10 kΩ or higher
      P20-6 (UP) - Body ground
    1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
    2. OK: Go to next step. 
  7. CHECK POWER WINDOW REGULATOR SWITCH ASSY (REAR LH) 
    1. Remove the regulator switch (the connector is connected).
    2. Turn the ignition switch ON.
