STEP 17. Check the ground circuit to the back door lock
key cylinder switch. Test at back door lock key cylinder
switch connector I-06.
(1) Disconnect back door lock key cylinder switch connector
I-06 measure the resistance available at the wiring harness
side of the connector.
(2) Measure the resistance value between terminal 2 and
ground.
• The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 19.
NO : Go to Step 18.
STEP 18. Check the wiring harness between back door
lock key cylinder switch connector I-06 (terminal 2) and
ground.
Q: Is the wiring harness between back door lock key
cylinder switch connector I-06 (terminal 2) 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
systems, which are described in "CIRCUIT
OPERATION", work normally, the input signal from
the back door lock key cylinder switch should be
normal.

STEP 19. Check ETACS-ECU connectors D-223 and D-224
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are ETACS-ECU connectors D-223 and D-224 in good
condition?
YES : Go to Step 20.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. If the systems, which are described in
"CIRCUIT OPERATION", work normally, the input
signal from the back door lock key cylinder switch
should be normal.

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
.
Q: Is the wiring harness between back door lock key
cylinder switch connector I-06 (terminals 1 and 3) and
ETACS-ECU connectors D-224 (terminal 28) and D-223
(terminal 45) in good condition?
YES : Replace the ETACS-ECU. If the systems, which are
described in "CIRCUIT OPERATION", work normally,
the input signal from the back door lock key cylinder
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
systems, which are described in "CIRCUIT
OPERATION", work normally, the input signal from
the back door lock key cylinder switch should be
normal.
STEP 21. Check driver's door lock key cylinder switch
connector H-03 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Is driver's door lock key cylinder switch connector H-03
in good condition?
YES : Go to Step 22.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. If the systems, which are described in
"CIRCUIT OPERATION", work normally, the input
signal from the driver's door lock key cylinder switch
should be normal.
STEP 22. Check the wiring harness between driver's door
lock key cylinder switch connector H-03 (terminal 2) and
ground.
