STEP 10. Check the front passenger's door lock key 
cylinder switch.
Disconnect front passenger's door lock key cylinder switch con-
nector H-18. Then check continuity between the switch termi-
nals.

Q: Is the front passenger's door lock key cylinder switch in 

good condition?
YES : 
Go to Step 11.
NO :  Replace the front passenger's door lock key cylinder 

switch. 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 ground circuit to the front passenger’s 
door lock key cylinder switch. Test at front passenger’s 
door lock key cylinder switch connector H-18.
(1) Disconnect front passenger's door lock key cylinder switch 

connector H-18 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 13.
NO :  Go to Step 12.

STEP 12. 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

.

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 ETACS-ECU connector D-223 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector D-223 in good condition?

YES : Go to Step 14.
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.
