INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (POWER SOURCE)

(a) Disconnect the power window switch (rear LH side) connector.

(b) 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.

2. INSPECT POWER WINDOW SWITCH (REAR LH SIDE)

(a) Remove the power window switch Removal.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPLACE POWER WINDOW SWITCH (REAR LH SIDE) Removal
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (SWITCH (REAR LH SIDE) - MOTOR (REAR LH SIDE))

(a) Disconnect the power window regulator motor assembly (rear LH 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.

4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH SIDE)

(a) Remove the power window regulator motor assembly Removal.

(b) Check power window regulator motor operation:

(1) Apply battery voltage to connector terminals 1 and 2.

NOTICE:
Do not apply battery voltage to any terminals except terminals 1 and 2.

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

OK:

(c) Check PTC operation:

NOTICE:
This check must be performed with the power window regulator and door glass installed on the vehicle.

(1) Install the power window regulator motor Installation.

(2) Connect an electrical tester DC 400 A probe to the wire harness of terminal 1.

NOTICE:
Match the arrow mark of the probe with the direction of the current flow.

(3) Fully close the door glass by pulling up the power window switch. Wait for approximately 60 seconds.

(4) Continue to pull up the power window switch and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (current shut-off inspection).

Standard:

4 to 90 seconds

(5) Wait for 60 seconds after the previous step, and then push down the power window switch (rear LH side).

OK:

The rear LH side window goes down.

NG -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH) Removal
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - SWITCH (REAR LH SIDE))

(a) Disconnect the power window master switch connector.

(b) Disconnect the power window switch (rear LH side) connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE POWER WINDOW MASTER SWITCH Removal
