NOTE: Also check intermediate connector D-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connectors 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 key

cylinder switch connector H-03 (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 driver's door lock key cylinder switch should be
normal.

STEP 23. Check driver's door lock key cylinder switch
connector H-03 and ETACS-ECU connector D-223 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are driver's door lock key cylinder switch connector

H-03 and ETACS-ECU connector D-223 in good
condition?
YES : Go to Step 24.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. 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 24. Check the wiring harness between driver's door
lock key cylinder switch connector H-03 (terminals 3) and
ETACS-ECU connector D-223 (terminals 50).

NOTE: Also check intermediate connector D-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connectors D-25 is damaged, Repair
or replace the damaged component(s) as described in GROUP

.

Q: Is the wiring harness between driver's door lock key

cylinder switch connector H-03 (terminals 3) and
ETACS-ECU connector D-223 (terminals 50) in good
condition?
YES : Replace the ETACS-ECU. 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.

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 driver's door lock key cylinder switch should be
normal.
