STEP 7. Check the wiring harness between driver's door
lock actuator switch connector H-10 (terminals 2 and 3)
and ETACS-ECU connector D-223 (terminals 56 and 55).

NOTE: Also check intermediate connector D-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-25 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 driver's door lock

actuator switch connector H-10 (terminals 2 and 3) and
ETACS-ECU connector D-223 (terminals 56 and 55) in
good condition?
YES : Replace the ETACS-ECU. If the functions, which are

described in "CIRCUIT OPERATION", work normally,
the input signal from the driver'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 driver's door lock actuator switch should be
normal.

STEP 8. Check the front passenger's door lock actuator
switch.
Disconnect front passenger's door lock actuator switch connec-
tor H-24. Then check continuity between the switch terminals.

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

good condition?
YES : Go to Step 9.
NO : Replace the front passenger's seat door lock actuator

switch. 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 9. Check the ground circuit to the front passenger’s
door lock actuator switch. Test at front passenger’s door
lock actuator switch connector H-24.
(1) Disconnect front passenger’s door lock actuator switch

connector H-24 and measure the resistance available at the
wiring harness side of the connector.

(2) Measure the resistance value between terminal 3 and

ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 12.
NO : Go to Step 10.

STEP 10. Check front passenger's door lock actuator
switch connector H-24 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Is front passenger's door lock actuator switch

connector H-24 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 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 11. Check the wiring harness between front
passenger's door lock actuator switch connector H-24
(terminal 3) 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 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 3) 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 front passenger's door lock actuator switch should
be normal.
