STEP 3. Check the front door lock actuator (RH).
Disconnect front door lock actuator (RH) connector E-05. Then 
check continuity between the terminals.

Q: Is the front door lock actuator (RH) in good condition?

YES : Go to Step 4.
NO :  Replace the front door lock actuator (RH). If the 

functions described in "CIRCUIT OPERATION" work 
normally, the input signal from the front door lock 
actuator (RH) should be normal.

STEP 4. Check the ground circuit to the front door lock 
actuator (RH). Measure the resistance at front door lock 
actuator (RH) connector E-05.
(1) Disconnect front door lock actuator (RH) connector E-05 

and measure the resistance available at the wiring harness 
side of the connector.

(2) Measure the resistance value between terminal 3 and 

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 6.
NO :  Go to Step 5.

STEP 5. Check the wiring harness between front door lock 
actuator (RH) connector E-05 (terminal 3) and ground.

NOTE: Also check intermediate connector C-12 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-12 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between front door lock actuator 

(RH) connector E-05 (terminal 3) 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 described in "CIRCUIT OPERATION" work 
normally, the input signal from the front door lock 
actuator (RH) should be normal.

STEP 6. Check ETACS-ECU connector C-217 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector C-217 in good condition?

YES : Go to Step 7.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the functions described in "CIRCUIT 

OPERATION" work normally, the input signal from the 
front door lock actuator (RH) should be normal.

STEP 7. Check the wiring harness between front door lock 
actuator (RH) connector E-05 (terminal 1) and ETACS-ECU 
connector C-217 (terminal 36).

NOTE: Also check intermediate connector C-12 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-12 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness

.

Q: Is the wiring harness between front door lock actuator 

(RH) connector E-05 (terminal 1) and ETACS-ECU 
connector C-217 (terminal 36) in good condition?
YES : Replace the ETACS-ECU. If the functions described 

in "CIRCUIT OPERATION" work normally, the input 
signal from the front door lock actuator (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 described in "CIRCUIT OPERATION" work 
normally, the input signal from the front door lock 
actuator (RH) should be normal.

STEP 8. Check front door lock actuator (LH) connector 
E-15 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is front door lock actuator (LH) connector E-15 in good 

condition?
YES : Go to Step 9.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the functions described in "CIRCUIT 

OPERATION" work normally, the input signal from the 
front door lock actuator (LH) should be normal.

STEP 9. Check the front door lock actuator (LH).
Disconnect front door lock actuator (LH) connector E-15. Then 
check continuity between the terminals.

Q: Is the front door lock actuator (LH) in good condition?

YES : Go to Step 10.
NO :  Replace the front door lock actuator (LH). If the 

functions described in "CIRCUIT OPERATION" work 
normally, the input signal from the front door lock 
actuator (LH) should be normal.
