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 12. Check front passenger's door lock key cylinder
switch connector H-18 and ETACS-ECU connector D-223
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are front passenger's door lock key cylinder switch

connector H-18 and ETACS-ECU connector D-223 in
good condition?
YES : Go to Step 13.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

. 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
or replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection

.

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.
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 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.
