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
.
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
. 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
Connector Inspection
.
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
. 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.
