P.42A-148

.

Q: Does the power window main switch work normally?

YES : Go to Step 4.
NO :  Replace the power window main switch. Verify that all 

the doors can be locked and unlocked normally.

STEP 4. Check the wiring harness between power window 
main switch connector E-19 (terminal No. 10) and ground. 

• Check the ground line for open circuit.

NOTE: Also check intermediate connector C-126 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-126 is damaged, repair 
or replace the damaged component(s) as described in GROUP 
00E, Harness Connector Inspection.
Q: Is the wiring harness between power window main 

switch connector E-19 (terminal No. 10) and ground in 
good condition?
YES : Go to Step 5.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary.

STEP 5. Check ETACS-ECU connector C-301, C-315 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are ETACS-ECU connector C-301, C-315 in good 

condition?
YES : Go to Step 6.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection

STEP 6. Check the wiring harness between power window 
main switch connector E-19 (terminal No. 13) and 
ETACS-ECU connector C-315 (terminal No. 15), between 
power window main switch connector E-19 (terminal No. 
14) and ETACS-ECU connector C-301 (terminal No. 2).

• Check the power supply line for open.

NOTE: Also check intermediate connector C-127 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-127 is damaged, repair 
or replace the damaged component(s) as described in GROUP

Q: Are the wiring harness between power window main 

switch connector E-19 (terminal No. 13) and 
ETACS-ECU connector C-315 (terminal No. 15), between 
power window main switch connector E-19 (terminal 
No. 14) and ETACS-ECU connector C-301 (terminal No. 
2) in good condition?
YES : Go to Step 7.
NO :  The wiring harness may be damaged or the connector 

may have loose, corroded or damaged terminals, or 
terminals pushed back in the connector. Repair the 
wiring harness as necessary. Verify that the central 
door locking system works normally.

STEP 7. Retest the system.
Check that the central door locking system works normally.
Q: Is the check result normal?

YES : No action is necessary and testing is complete.
NO :  Replace the power window main switch. Check that 

the central door locking system normally.

CIRCUIT OPERATION

• The ETACS-ECU controls the central door lock-

ing system, locking or unlocking all doors by acti-
vating the central door lock relay (built into the 
ETACS-ECU). The ETACS-ECU uses inputs from 
the following components:

• Door lock actuators

• Door lock switch, which is incorporated in the 

power window main switch or front power win-
dow sub switch

.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

• The front power window sub switch may be 

defective

DIAGNOSTIC PROCEDURE

STEP 1. Checking central door unlocking operation
Check that the central door locking system works normally.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Refer to Inspection procedure A-1 "Central door 

locking system does not work at all 

P.42A-38

."

STEP 2. Check front power window sub switch connector 
E-05 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is front power window sub switch connector E-05 in 

good condition?
YES : Go to Step 3.
NO :  Repair or check the connector. Refer to GROUP 00E, 

Harness Connector Inspection 

P.00E-2

. Verify that all 

the doors can be locked and unlocked normally.
