STEP 11. Check the wiring harness between rear door
switch (RH) connector F-05 (terminal 2) and ETACS-ECU
connector D-222 (terminal 7).

NOTE: Also check intermediate connector D-111 and junction
block connector D-209 for loose, corroded, or damaged termi-
nals, or terminals pushed back in the connector. If junction
block connector D-209 or intermediate connector D-111 is dam-
aged, 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 switch (RH)

connector F-05 (terminal 2) and ETACS-ECU connector
D-222 (terminal 7) 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 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 switch (RH) should be normal.

STEP 12. Check back door switch connector G-15 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are back door switch connector G-15 in good

condition?
YES : Go to Step 13.
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 back door switch should be normal.

STEP 13. Check the back door switch.
Remove the back door switch. Then check continuity between
the switch terminals and the switch body.

Q: Is the back door switch in good condition?

YES : Go to Step 14.
NO : Replace the back door switch. If the functions, which

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

STEP 14. Measure at the lower metal part of the back door
switch in order to check the ground circuit to the back
door switch.
NOTE: Check that the back door switch is grounded to the
vehicle body by means of its mounting screw.
Remove the cap, and measure the resistance value between
the lower metal part and the ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 15.
NO : Check the fit of the switch, and repair if necessary. If

the functions, which are described in "CIRCUIT
OPERATION", work normally, the input signal from
the back door switch should be normal.

.

Q: Is the wiring harness between back door switch

connector G-15 (terminal 2) and ETACS-ECU connector
D-222 (terminal 7) 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 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 switch should be normal.

STEP 17. Check rear door switch (LH) connector F-09 and
ETACS-ECU connector D-222 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are rear door switch (LH) connector F-09 and

ETACS-ECU connector D-222 in good condition?
YES : Go to Step 18.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection
