3. CHECK HARNESS AND CONNECTOR (POWER WINDOW MASTER SWITCH - FRONT DOOR ECU (DRIVER SIDE))

(a) Disconnect the Q13 power window master switch connector.

(b) Disconnect the M9 front door ECU connector.

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

4. CHECK HARNESS AND CONNECTOR (POWER WINDOW MASTER SWITCH INPUT POWER SUPPLY)

(a) Measure the voltage according to the value(s) in the table below.

Standard voltage:

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

5. CHECK HARNESS AND CONNECTOR (FRONT DOOR ECU (DRIVER SIDE) - REGULATOR MOTOR (DRIVER SIDE))

(a) Disconnect the M11 motor 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. CHECK HARNESS AND CONNECTOR (POWER WINDOW MASTER SWITCH - REGULATOR MOTOR (DRIVER SIDE))

(a) 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.

7. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)

(a) Remove the front power window regulator motor assembly (for Driver Side) Service and Repair.

(b) Apply positive (+) battery voltage to the connector terminal 2 (B).

NOTICE:
* Do not apply positive (+) battery voltage to any terminals, except terminal 2 (B), to avoid damaging the pulse sensor inside the motor.
* Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly onto the door.
(c) Apply negative (-) battery voltage to the connector terminals 1 (E) and 7 (DWN1) / 10 (UP1).

(d) Check that the motor gear rotates smoothly as follows.

OK:

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

OK -- REPLACE POWER WINDOW MASTER SWITCH
