Driver Side Power Window Auto Up / Down Function Does Not Operate With Power Window Master Switch

WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch

Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch

DESCRIPTION

- If the pulse sensor on the front power window regulator motor assembly (for driver side) malfunctions, the regulator will enter fail-safe mode, and the AUTO UP/DOWN function will not operate.
- If the power window initialization Initialization has not been performed, the AUTO UP/DOWN function will not operate.

WIRING DIAGRAM





INSPECTION PROCEDURE
NOTICE:
- When the front power window regulator motor assembly (for driver side) connector or the multiplex network master switch assembly connector is disconnected, the power window control system must be initialized Initialization.
- Since the power window control system has functions that use multiplex communication, first confirm that there is no malfunction in the multiplex communication system by inspecting the multiplex communication functions in accordance with the How to Proceed with Troubleshooting procedure How To Proceed With Troubleshooting. Then, conduct the following inspection procedure.

PROCEDURE

1. CHECK POWER WINDOW CONTROL SYSTEM (LED ILLUMINATION CHECK (for Driver Side))
(a) Turn the engine switch on (IG).
(b) Operate the multiplex network master switch assembly's driver side switch for 2 seconds or more.
(c) Check the blinking pattern of the LED illumination. Compare the blinking pattern with the illustration below.
HINT: If there is a malfunction in the pulse sensor, manually operating the multiplex network master switch assembly or multiplex network switch assembly will cause the multiplex network master switch assembly or multiplex network switch assembly LED illumination to blink. The LED illumination continues to blink for 45 seconds or until the engine switch is turned off. After 45 seconds, the multiplex network master switch assembly or multiplex network switch assembly LED illumination remains on.





Result:






B -- CHECK HARNESS AND CONNECTOR (MASTER SWITCH - REGULATOR MOTOR (for Driver Side))
A -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
C -- Continue to next step.
2. PERFORM INITIALIZATION (POWER WINDOW CONTROL SYSTEM (for Driver Side))
(a) Initialize the power window control system (for driver side) Initialization.
NEXT -- Continue to next step.
3. CHECK POWER WINDOW CONTROL SYSTEM (DRIVER SIDE AUTO UP/DOWN FUNCTION)
(a) Check that the driver side auto UP/DOWN function operates normally Component Tests and General Diagnostics.
OK:
Driver side auto UP/DOWN function operates normally.
NG -- INSPECT MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE)
OK -- END (INITIALIZATION IS DEFECTIVE)
4. INSPECT MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE)
(a) Turn the engine switch on (IG).





(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:






NG -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - REGULATOR MOTOR (for Driver Side))
(a) Disconnect the front power window regulator motor assembly (for driver 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 -- Continue to next step.
6. REPLACE FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)
(a) Replace the front power window regulator motor assembly Removal.
NEXT -- Continue to next step.
7. PERFORM INITIALIZATION (POWER WINDOW CONTROL SYSTEM (for Driver Side))
(a) Initialize the power window control system (for driver side) Initialization.
NEXT -- Continue to next step.
8. CHECK POWER WINDOW CONTROL SYSTEM (DRIVER SIDE AUTO UP/DOWN FUNCTION)
(a) Check that the driver side auto UP/DOWN function operates normally Component Tests and General Diagnostics.
OK:
Driver side auto UP/DOWN function operates normally.
NG -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
OK -- END (POWER WINDOW REGULATOR MOTOR IS DEFECTIVE)
