STEP 10. Check front passenger's door lock key cylinder 
switch connector H-18 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Is front passenger's door lock key cylinder switch 

connector H-18 in good condition?
YES : 
Go to Step 11.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the systems, which are described in 

"CIRCUIT OPERATION", work normally, the input 
signal from the front passenger's door lock key 
cylinder switch should be normal.

STEP 11. Check the wiring harness between front 
passenger's door lock key cylinder switch connector H-18 
(terminal 2) and ground.

NOTE: Also check intermediate connector D-15 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connectors D-15 is damaged, Repair 
or replace the damaged component(s) as described in GROUP 
00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between front passenger's door 

lock key cylinder switch connector H-18 (terminal 2) and 
ground in good condition?
YES : 
No action is necessary and testing is complete.
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. If the 
systems, which are described in "CIRCUIT 
OPERATION", work normally, the input signal from 
the front passenger's door lock key cylinder switch 
should be normal.

STEP 13. Check the wiring harness between front 
passenger's door lock key cylinder switch connector H-18 
(terminals 1 and 3) and ETACS-ECU connector D-223 
(terminals 50 and 51).

NOTE: Also check intermediate connector D-15 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connectors D-15 is damaged, Repair

Q: Is the wiring harness between front passenger's door 

lock key cylinder switch connector H-18 (terminals 1 
and 3) and ETACS-ECU connector D-223 (terminals 50 
and 51) in good condition?
YES : 
Replace the ETACS-ECU. If the systems, which are 

described in "CIRCUIT OPERATION", work normally, 
the input signal from the front passenger's door lock 
key cylinder switch should be normal.

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.

STEP 14. Check the back door lock key cylinder switch.
Disconnect back door lock key cylinder switch connector I-06. 
Then check continuity between the switch terminals.

Q: Is the back door lock key cylinder switch in good 

condition?
YES : 
Go to Step 15.
NO :  Replace the back door lock key cylinder switch. If the 

systems, which are described in "CIRCUIT 
OPERATION", work normally, the input signal from 
the back door lock key cylinder switch should be 
normal.

STEP 15. Check the ground circuit to the back door lock 
key cylinder switch. Test at back door lock key cylinder 
switch connector I-06.
(1) Disconnect back door lock key cylinder switch connector I-

06 measure the resistance available at the wiring harness 
side of the connector.

(2) Measure the resistance value between terminal 2 and 

ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 18.
NO :  Go to Step 16.
