Driver Side Power Window Does Not Operate With Power Window Master Switch

WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: Driver Side Power Window does not Operate with Power Window Master Switch
- Driver Side Power Window does not Operate with Power Window Master Switch

DESCRIPTION

* When the engine is running or the ignition switch is ON, the driver door power window regulator motor is driven by operating the power window regulator master switch. The driver door power window regulator motor has motor, regulator, and ECU functions.

NOTICE:
* The power window control system uses a multiplex communication system (LIN). Inspect the communication function by following HOW TO PROCEED WITH TROUBLESHOOTING. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
* When the power window regulator motor assembly (on the driver 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 resumed by repeating the following operation at least 5 times:
(1) Close the power window by fully pulling up the power window switch and holding it at the AUTO UP position.
(2) Open the power window by fully pushing down the switch.
* When the ECU determines that the driver door power window regulator motor has a malfunction, DTC B2311 is set.

HINT
If the pulse sensor built into the power window regulator motor (on the driver 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 switch in the AUTO UP position, and opened manually by pushing down the switch.)

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC

(a) Check for DTCs.

(b) Connect Techstream to the DLC3.

(c) By following the tester screen display, check whether any DTCs are output.

Result





B -- GO TO DIAGNOSTIC TROUBLE CODE CHART
A -- Continue to next step.

2. PERFORM ACTIVE TEST USING TECHSTREAM (POWER WINDOW UP/DOWN)

(a) Perform the Active Test, using Techstream to generate a control command, and then check the power window operation.

D-Door Motor





OK:

Driver side power window operates normally.

CAUTION:
Be careful to avoid injuries as this test causes vehicle parts to move.

NG -- INSPECT FUSE (D FR DOOR)
OK -- Continue to next step.

3. READ VALUE USING TECHSTREAM (MASTER SWITCH)

(a) Check the Data list for proper functioning of the power window master switch.

D-Door Motor





OK:

ON (switch operates) appears on screen.

OK -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)
NG -- Continue to next step.

4. CHECK WIRE HARNESS (SWITCH INPUT POWER SUPPLY)





(a) Disconnect the H2 switch connector.

(b) Turn the ignition switch ON.

(c) Measure the voltage of the wire harness side connector.

Standard voltage:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

5. CHECK WIRE HARNESS (MASTER SWITCH - REGULATOR MOTOR)





(a) Disconnect the H2 switch connector.

(b) Disconnect the H4 motor connector.

(c) Measure the resistance of the wire harness side connectors.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR

OK -- REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY

6. INSPECT FUSE (D FR DOOR)

(a) Remove the D FR DOOR fuse from the instrument panel junction block.

Standard resistance:

Below 1 Ohms

NG -- REPLACE FUSE (D FR DOOR)
OK -- Continue to next step.

7. CHECK WIRE HARNESS (MOTOR INPUT POWER SUPPLY)





(a) Disconnect the H4 motor connector.

(b) Measure the voltage of the wire harness side connector.

Standard voltage:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR

OK -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)
