STEP 19. 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.

STEP 20. Check the rear door lock actuator switch (RH).
Disconnect rear door lock actuator switch (RH) connector H-21.
Then check continuity between the switch terminals.

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

condition?
YES : Go to Step 21.
NO : Replace the rear door lock actuator switch (RH). If the

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

STEP 21. Check the ground circuit to the rear door lock
actuator switch (RH). Test at rear door lock actuator switch
(RH) connector H-21.
(1) Disconnect rear door lock actuator switch (RH) connector

H-21 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 24.
NO : Go to Step 22.

STEP 22. Check rear door lock actuator switch (RH)
connector H-21 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Is rear door lock actuator switch (RH) connector H-21 in

good condition?
YES : Go to Step 23.
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 (RH)
should be normal.

STEP 23. Check the wiring harness between rear door lock
actuator switch (RH) connector H-21 (terminal 6) and
ground.

NOTE: Also check intermediate connector F-23 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector F-23 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 (RH) connector H-21 (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 (RH) should be
normal.
