Rear Power Window LH Does Not Operate With Rear Power Window Switch LH
WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: Rear Power Window LH does not Operate with Rear Power Window Switch LH
Rear Power Window LH does not Operate with Rear Power Window Switch LH
DESCRIPTION
When the engine is running or the engine switch is on (IG), the power window regulator motor assembly (for rear LH side) is operated by the power window regulator switch assembly (for rear LH side). The power window regulator motor assembly (for rear LH side) has motor, regulator, and ECU functions.
HINT:
If the pulse sensor built into the power window regulator motor assembly (for rear LH side) malfunctions, the power window control system enters fail-safe mode. The remote up/down and auto up/down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator switch assembly (for rear LH side) in the auto up position, and opened manually by pushing down the power window regulator switch assembly (for rear LH side).
WIRING DIAGRAM
INSPECTION PROCEDURE
NOTICE:
- 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).
- When the ECU determines that the power window regulator motor assembly (for rear LH side) has a malfunction, DTC B2311 is set.
PROCEDURE
1. PERFORM ACTIVE TEST USING TECHSTREAM (RL-Door Motor)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / RL-Door Motor / Active Test.
(e) Perform the Active Test according to the display on the Techstream.
RL-Door Motor (Power Window Regulator Motor Assembly (for Rear LH Side))
OK:
Rear LH 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 -- CHECK HARNESS AND CONNECTOR (REGULATOR MOTOR - BATTERY AND BODY GROUND)
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM (RL-Door Motor)
(a) Enter the following menus: Body Electrical / RL-Door Motor / Data List.
(b) Read the Data List according to the display on the Techstream.
RL-Door Motor (Power Window Regulator Motor Assembly (for Rear LH Side))
OK:
On the Techstream screen, ON or OFF is displayed accordingly.
NG -- INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Rear LH Side)
OK -- Continue to next step.
3. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH Side)
(a) Replace the power window regulator motor assembly (for rear LH side) Removal.
NEXT -- Continue to next step.
4. CHECK MANUAL UP / DOWN FUNCTION
(a) Check that the rear LH side door power window moves when the manual up/down function of the power window regulator assembly (for rear LH side) is operated Component Tests and General Diagnostics.
OK:
Rear LH side manual up/down function is normal.
NG -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
OK -- END (POWER WINDOW REGULATOR MOTOR ASSEMBLY IS DEFECTIVE)
5. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Rear LH Side)
(a) Remove the power window regulator switch assembly (for rear LH side) Removal.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Rear LH side)
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (REAR LH SIDE SWITCH - REAR LH SIDE MOTOR AND BODY GROUND)
(a) Disconnect the power window regulator motor assembly (for rear LH side) connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH side)
7. CHECK HARNESS AND CONNECTOR (REGULATOR MOTOR - BATTERY AND BODY GROUND)
(a) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH side)
