Rear Power Window RH Does Not Operate With Rear Power Window Switch RH

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

Rear Power Window RH does not Operate with Rear Power Window Switch RH

DESCRIPTION

When the engine is running or the ignition switch is ON, the power window regulator motor assembly (for rear RH side) is operated by the power window regulator switch assembly (for rear RH side). The power window regulator motor assembly (for rear RH side) has motor, regulator, and ECU functions.
HINT: If the pulse sensor built into the power window regulator motor (for rear RH 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 RH side) at the auto up position, and opened manually by pushing down the power window regulator switch assembly (for rear RH side).

INSPECTION PROCEDURE
NOTICE:
- When the power window regulator motor assembly (for rear RH 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 RH 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 RH side).

PROCEDURE

1. CHECK REMOTE UP / DOWN FUNCTION
(a) Check that the remote up/down function using the power window regulator master switch assembly operates the power windows Operation Check.
OK:
Remote up/down function is normal.

NG -- CHECK HARNESS AND CONNECTOR (REAR RH SIDE MOTOR - BATTERY AND BODY GROUND)
OK -- Continue to next step.

2. INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Rear RH Side)




(a) Remove the power window regulator switch assembly (for rear RH side) Removal.
(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. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear RH Side)
(a) Remove the power window regulator motor assembly (for rear RH side) Removal.




(b) Apply positive (+) battery voltage to connector terminal 2 (B).
NOTICE: Do not apply positive (+) battery voltage to any terminals other than terminal 2 (B) to avoid damaging the pulse sensor inside the motor.
(c) Connect a ground lead to connector terminals 1 (GND) and 7 (DOWN) or 10 (UP).
(d) Check that the motor gear rotates smoothly as follows:
OK:
