SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-88

POSSIBLE CAUSES

• Malfunction of the front power window sub 

switch, rear power window sub switch (RH) or 
rear power window sub switch (LH)

• Malfunction of the front power window regulator 

motor (RH) <LH drive vehicles>, front power win-
dow regulator motor (LH) <RH drive vehicles>, 
rear power window regulator motor (RH) or rear 
power window regulator motor (LH)

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the power window main switch.
Check that the power window lock switch is turned 
off.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Turn off the power window lock switch.

Step 2. Determine a trouble spot.

Q: Which power window does not work?

Front passenger's door <LH drive vehicles> : 

Go 

to Step 3.

Front passenger's door <RH drive vehicles> : 

Go 

to Step 12.

Rear right door : 

Go to Step 21.

Rear left door : 

Go to Step 30.

Step 3. Connector check: E-14 front power 
window sub switch connector

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the connector.

Step 4. Resistance measurement at E-14 front 
power window sub switch connector

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Resistance between E-14 front power window 

sub switch connector terminal No.1 and body 
earth

OK: 2

Ω or less

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 5.

Step 5. Check the wiring harness from E-14 front 
power window sub switch connector terminal 
No.1 to body earth.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector C-110, and repair if necessary.

• Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00, How to 
Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

Step 6. Voltage measurement at E-14 front power 
window sub switch connector

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Turn the ignition switch to the ON position.

(3) Voltage between E-14 front power window sub 

switch connector terminal No.4 and body earth

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 9.

NO : 

Go to Step 7.

Step 7. Connector check: C-224 power window 
relay connector

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the connector.

Step 8. Check the wiring harness from E-14 front 
power window sub switch connector terminal 
No.4 to C-224 power window relay connector 
terminal No.4.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connectors C-110 and junction block connector 
C-211, and repair if necessary.

• Check the power supply line for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00, How to 
Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

Step 9. Connector check: E-11 front power 
window regulator motor (RH) connector

Q: Is the check result normal?

YES : 

Go to Step 10.

NO : 

Repair the connector.

Step 10. Check the wiring harness from E-11 
front power window regulator motor (RH) 
connector terminal Nos.1 and 4 to E-14 front 
power window sub switch connector terminal 
Nos.5 and 7.

• Check the input and output lines for open or short 

circuit.
