STEP 25. Check the wiring harness between rear door lock
actuator switch (RH) connector H-21 (terminal 4) and
ETACS-ECU connector D-223 (terminal 47).

NOTE: Also check intermediate connectors D-111 and F-23 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connectors D-111 or 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 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 rear door lock actuator
switch (RH) 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 (RH) should be
normal.

STEP 26. Check the back door lock actuator switch.
Disconnect back door lock actuator switch connector I-05.
Then check continuity between the switch terminals.

Q: Is the back door lock actuator switch in good

condition?
YES : Go to Step 27.
NO : Replace the back door lock actuator switch. 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 27. Check the ground circuit to the back door lock
actuator switch. Test at back door lock actuator switch
connector I-05.
(1) Disconnect back door lock actuator switch connector I-05

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 30.
NO : Go to Step 28.

STEP 28. Check back door lock actuator switch connector
I-05 for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is back door lock actuator switch connector I-05 in good

condition?
YES : Go to Step 29.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

. 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 29. Check the wiring harness between back door
lock actuator switch connector I-05 (terminal 6) and
ground.
Q: Is the wiring harness between back door lock actuator

switch connector I-05 (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 back door lock actuator switch should be normal.
