Rear Power Window RH Auto Up / Down Function Does Not Operate With Rear Power Window Switch RH

WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Rear Power Window RH Auto Up / Down Function does not Operate with Rear Power Window Switch RH

Rear Power Window RH Auto Up / Down Function does not Operate with Rear Power Window Switch RH

DESCRIPTION

- If the pulse sensor on the rear power window regulator motor assembly (for rear RH 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 rear power window regulator motor assembly (for rear RH side) connector or the multiplex network switch assembly (for rear RH 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 Rear RH Side)
(a) Turn the engine switch on (IG).
(b) Operate the multiplex network switch assembly (for rear RH 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 Rear RH Side))
A -- REPLACE MULTIPLEX NETWORK SWITCH ASSEMBLY (for Rear RH Side)
C -- Continue to next step.
2. PERFORM INITIALIZATION (POWER WINDOW CONTROL SYSTEM (for Rear RH Side))
(a) Initialize the power window control system (for rear RH side) Initialization.
NEXT -- Continue to next step.
3. CHECK POWER WINDOW CONTROL SYSTEM (REAR RH SIDE AUTO UP/DOWN FUNCTION)
(a) Check that the rear RH side auto UP/DOWN function operates normally Component Tests and General Diagnostics.
OK:
Rear RH side auto UP/DOWN function operates normally.
NG -- INSPECT MULTIPLEX NETWORK SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE (for Rear RH Side))
OK -- END (INITIALIZATION IS DEFECTIVE)
4. INSPECT MULTIPLEX NETWORK SWITCH ASSEMBLY (PULSE SENSOR POWER SOURCE (for Rear RH 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 Rear RH Side)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (SWITCH (for Rear RH Side) - REGULATOR MOTOR)
(a) Disconnect the front power window regulator motor assembly (for rear RH side) connector.
(b) Disconnect the multiplex network assembly (for rear RH side) connector.

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