STEP 31. Check the wiring harness between back door 
lock actuator switch connector I-05 (terminal 4) and 
ETACS-ECU connector D-223 (terminal 47).

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 

P.00E-2

.

Q: Is the wiring harness between back door lock actuator 

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

STEP 32. Check the wiring harness between driver's door 
lock actuator switch connector H-10 (terminal 1) 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 connector 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 

actuator switch connector H-10 (terminal 1) 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 driver's door lock actuator switch should be 
normal.

STEP 33. Check ETACS-ECU connector D-223 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is the rear lock actuator switch good condition? 

YES : Go to Step 34.
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 rear door lock actuator switch (LH) 
should be normal.
