Front Passenger Side Power Window Auto Up / Down Function Does Not Operate With Front Passenger Side Power Window Switch

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

Front Passenger Side Power Window Auto Up / Down Function does not Operate with Front Passenger Side Power Window Switch

DESCRIPTION

- If the pulse sensor on the front power window regulator motor assembly (for front passenger 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 front passenger side) connector or the multiplex network switch assembly (for front passenger side) connector is disconnected, the power window control system must be initialized Initialization.
- Since the power window control system has functions that use multiplex communication (BEAN), 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 (for Front Passenger Side)
(a) Turn the engine switch on (IG).
(b) Operate the multiplex network switch assembly (for front passenger side) 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 -- INSPECT MULTIPLEX NETWORK SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE (for Front Passenger Side))
A -- REPLACE MULTIPLEX NETWORK SWITCH ASSEMBLY (for Front Passenger Side)
C -- Continue to next step.
2. PERFORM INITIALIZATION (POWER WINDOW CONTROL SYSTEM (for Front Passenger Side))
(a) Initialize the power window control system (for front passenger side) Initialization.
NEXT -- Continue to next step.
3. CHECK POWER WINDOW CONTROL SYSTEM (FRONT PASSENGER SIDE AUTO UP/DOWN FUNCTION)
(a) Check that the front passenger side auto UP/DOWN function operates normally Component Tests and General Diagnostics.
OK:
Front passenger side auto UP/DOWN function operates normally.
NG -- INSPECT MULTIPLEX NETWORK SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE (for Front Passenger Side))
OK -- END (INITIALIZATION IS DEFECTIVE)
4. INSPECT MULTIPLEX NETWORK SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE (for Front Passenger Side))
(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 SWITCH ASSEMBLY (for Front Passenger Side)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (SWITCH (for Front Passenger Side) - Regulator Motor)
(a) Disconnect the front power window regulator motor assembly (for front passenger side) connector.
(b) Disconnect the multiplex network assembly (for front passenger side) connector.

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