STEP 31. Check the wiring harness between back door
lock actuator switch connector I-05 (terminal 4) and
ETACS-ECU connector D-223 (terminal 47).

NOTE: Also check intermediate connectors D-111 and G-11 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connectors D-111 or G-11
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 back door lock actuator

switch connector I-05 (terminal 4) and ETACS-ECU
connector D-223 (terminal 47) in good condition?
YES : Replace the ETACS-ECU. If the functions, which are

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

STEP 32. Check the wiring harness between driver's door
lock actuator switch connector H-10 (terminal 1) and
ground.

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 (terminal 1) 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 driver's door lock actuator switch should be
normal.

STEP 33. Check ETACS-ECU connector D-223 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is the rear lock actuator switch good condition?

YES : Go to Step 34.
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 34. Check the wiring harness between rear door lock
actuator switch (LH) connector H-13 (terminal 5) and
ETACS-ECU connector D-223 (terminal 47).

NOTE: Also check intermediate connectors D-125 and F-12 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connectors D-125 or 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 5) and ETACS-ECU
connector D-223 (terminal 47) in good condition?
YES : Replace the ETACS-ECU. 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.

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.
