STEP 16. Check back door lock key cylinder switch 
connector I-06 for loose, corroded or damaged terminals, 
or terminals pushed back in the connector.
Q: Is back door lock key cylinder switch connector I-06 in 

good condition?
YES : Go to Step 17.
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 back door lock key cylinder switch 
should be normal.

STEP 17. 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.

Q: Are back door lock key cylinder switch connector I-06, 

ETACS-ECU connectors D-223 and D-224 in good 
condition?
YES : Go to Step 19.
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 back door lock key cylinder switch 
should be normal.

STEP 19. Check 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).

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

STEP 21. Check the wiring harness between driver's door 
lock key cylinder switch connector H-03 (terminal 2) and 
ground.

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
