DIAGNOSIS PROCEDURE

Step 1. ECU check by using the SWS monitor.
Check that the power supply and earth lines to the 
power window main switch (power window module) 
and the SWS communication lines are normal.

• Turn the ignition switch to the ON position.

ECUS TO BE CHECKED

• P/W MODULE

OK: "OK" is displayed on the "P/W MOD-
ULE" menu.

Q: Is the check result normal?

main switch (power window module) is not 
possible 

P.54C-47

."

Step 2. Check the power window sub switch.
Check that each power window works by means of 
the respective power window sub switch when the 
power window lock switch is turned off.

Check the SWS communication signals, which are 
used when the front and/or rear passenger's door 
power windows are operated by the power window 
main switch.

<Selected item> DOOR CNT. COM. 

• Insert a probe between a power window sub 

switch of a door of which power window does not 
work and the power window main switch (For the 
insertion point, refer to 

P.54C-5

).

• Turn the ignition switch to the ON position.

• Are normal conditions displayed when each 

switch of the power window main switch is oper-
ated?

OK: Normal conditions are displayed for all 
the items.

Q: Is the check result normal?

Normal conditions are displayed for all of items C0, 
C1 and C2 when the front passenger's power 
window does not work. : 

Go to Step 5.

Normal conditions are displayed for none of items 
C0, C1 and C2 when the front passenger's power 
window does not work. : 

Go to Step 7.

Normal conditions are displayed for all of items C4, 
C5 and C6 when the rear right power window does 
not work. : 

Go to Step 10.

Normal conditions are displayed for none of items 
C4, C5 and C6 when the rear right power window
