Check Power Window Serial Link

NIS000ES

1. 

CHECK POWER WINDOW SWITCH OUTPUT SIGNAL

 With CONSULT-II

Check door lock and unlock switch (“LOCK SW DR/AS”, “UNLK SW DR/AS”) in DATA MONITOR mode for
“POWER DOOR LOCK SYSTEM” with CONSULT-II. Refer to 

BL-36

 .

●

When door lock and unlock switch is turned to LOCK 

●

When door lock and unlock switch is turned to UNLOCK 

 Without CONSULT-II

1.

Remove key from ignition switch, and the door of driver side and passenger side is closed.

2.

Check the signal between BCM connector and ground with oscilloscope when door lock and unlock
switch (driver side and passenger side) is turned “LOCK” or “UNLOCK”.

3.

Make sure signals which are shown in the figure below can be detected during 10 second just after door
lock and unlock switch (driver side and passenger side) is turned “LOCK” or “UNLOCK”.

OK or NG

OK

>> GO TO 2.

NG

>> GO TO 3.

2. 

CHECK BCM OUTPUT SIGNAL

Check power window serial link (“POWER WINDOW DOWN”) in “ACTIVE TEST” mode for “REMOTE KEY-
LESS ENTRY SYSTEM” with CONSULT-II. Refer to 

BL-63, "Active Test"

 .

When “ACTIVE TEST” is executed, is the window of driver side and
passenger side lowered.

OK or NG

OK

>> Further inspection is necessary. Refer to symptom

chart.

NG

>> Replace BCM.
