Driver Side Power Window Does Not Operate With Power Window Master Switch

WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Driver Side Power Window does not Operate with Power Window Master Switch

Driver Side Power Window does not Operate with Power Window Master Switch

DESCRIPTION

When the engine is running or the engine switch is on (IG), the front power window regulator motor assembly (for driver side) is operated by the multiplex network master switch assembly. The front power window regulator motor assembly (for driver side) has motor, regulator, and sensor functions.

WIRING DIAGRAM

INSPECTION PROCEDURE
NOTICE:
- When the front power window regulator motor assembly (for driver side) connector or the multiplex network master switch assembly 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 FUSES (FR DOOR LH, ECU-IG RH and MPX-B)
(a) Remove the FR DOOR LH fuse from the main body ECU LH (cowl side junction block LH).
(b) Remove the ECU-IG RH fuse from the main body ECU RH (cowl side junction block RH).
(c) Remove the MPX-B fuse from the engine room relay block No. 1.
(d) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPLACE FUSE
OK -- Continue to next step.
2. PERFORM ACTIVE TEST USING TECHSTREAM (DRIVER SIDE POWER WINDOW UP/DOWN)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Master Switch / Active Test.
(e) Perform the Active Test according to the display on the Techstream.

Master Switch (Multiplex Network Master Switch Assembly)

OK:
Driver side power window operates normally.
CAUTION: Be careful to avoid injuries as this test causes vehicle parts to move.
During the Active Test, the jam protection function will not operate.

NG -- CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH - BODY GROUND AND BATTERY)
OK -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
3. CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH - BODY GROUND AND BATTERY)

(a) Disconnect the multiplex network master switch assembly 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 FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)

(a) Remove the front power window regulator motor assembly (for driver side) 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 front power window regulator motor assembly (for driver side) Installation.

(2) Connect an electrical tester DC 400 A probe to the wire harness of terminal 2.
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 multiplex network master switch assembly. Wait for approximately 60 seconds.
(4) Continue to pull up the multiplex network master switch assembly 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 press the multiplex network master switch assembly.
OK:
The driver side window goes down.
NG -- REPLACE FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - REGULATOR MOTOR (for Driver Side))
(a) Disconnect the front power window regulator motor assembly (for driver 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 -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
