DIAGNOSIS PROCEDURE

Step 1. Check the power window main switch.
Check that the driver's power window works by 
means of the power window main switch.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to inspection procedure D-2 "Driver's 
power window does not work by means of 
the power window main switch <LH drive 
vehicles>

P.54B-81

 ." Refer to inspection 

procedure D-2 "Driver's power window does 
not work by means of the power window 
main switch <RH drive vehicles>

P.54B-83

 ."

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.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Refer to inspection procedure D-3 "Relevant 
power window(s) do not work by means of 
the front and rear passenger's power

Step 5. Check the wiring harness between E-05 
power window main switch connector terminal 
No.11 and E-14 front power window sub switch 
connector terminal No.6.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connectors C-17, C-110, and repair if neces-
sary.

• Check the communication lines for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the wiring harness.

Step 6. Retest the system.
After the front power window sub switch is replaced, 
check that the front passenger's door power window 
can be operated by the power window sub switch.
(1) Replace the front power window sub switch.
(2) Check that the front passenger's power window 

works by means of the power window main 
switch.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent
