STEP 13. Check the wiring harness between front
passenger's door lock actuator switch connector H-24
(terminal 2) and ETACS-ECU connector D-223 (terminal
46).

NOTE: Also check intermediate connector D-15 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector 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 actuator switch connector H-24 (terminal 2) and
ETACS-ECU connector D-223 (terminal 46) in good
condition?
YES : Replace the ETACS-ECU. If the functions, which are

described in "CIRCUIT OPERATION", work normally,
the input signal from the front passenger's door lock
actuator 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
functions, which are described in "CIRCUIT
OPERATION", work normally, the input signal from
the front passenger's door lock actuator switch should
be normal.

STEP 14. Check the rear door lock actuator switch (LH).
Disconnect rear door lock actuator switch (LH) connector H-13.
Then check continuity between the switch terminals.

Q: Is the rear door lock actuator switch (LH) in good

condition?
YES : Go to Step 15.
NO : Replace the rear door lock actuator switch (LH). If the

functions, which are described in "CIRCUIT
OPERATION", work normally, the input signal from
the rear door lock actuator switch (LH) should be
normal.

STEP 15. Check the ground circuit to the rear door lock
actuator switch (LH). Test at rear door lock actuator switch
(LH) connector H-13.
(1) Disconnect rear door lock actuator switch (LH) connector H-

13 and measure the resistance available at the wiring
harness side of the connector.

(2) Measure the resistance value between terminal 6 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.

STEP 16. Check rear door lock actuator switch (LH)
connector H-13 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Is rear door lock actuator switch (LH) connector H-13 in

good condition?
YES : Go to Step 17.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. If the functions, which are described in

"CIRCUIT OPERATION", work normally, the input
signal from the rear door lock actuator switch (LH)
should be normal.

STEP 17. Check the wiring harness between rear door lock
actuator switch (LH) connector H-13 (terminal 6) and
ground.

NOTE: Also check intermediate connector F-12 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector F-12 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 rear door lock actuator

switch (LH) connector H-13 (terminal 6) 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
functions, which are described in "CIRCUIT
OPERATION", work normally, the input signal from
the rear door lock actuator switch (LH) should be
normal.
