STEP 2. Check ETACS-ECU connector C-219 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector C-219 in good condition?

YES : Go to Step 3.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the central door locking system 

works normally.

STEP 3. Check the battery power supply circuit to the 
ETACS-ECU. Measure the voltage at ETACS-ECU 
connector C-219.
(1) Disconnect ETACS-ECU connector C-219 and measure the 

voltage available at the junction block side of the connector.

(2) Measure the voltage between terminal 2 and ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage)

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 5.
NO :  Go to Step 4.

STEP 4. Check the wiring harness between ETACS-ECU 
connector C-219 (terminal 2) and fusible link (1).

NOTE: Also check junction block connector C-216 and inter-
mediate connector C-29 for loose, corroded, or damaged termi-
nals, or terminals pushed back in the connector. If junction 
block connector C-216 or intermediate connector C-29 is dam-
aged, repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

C-219 (terminal 2) and fusible link (1) in good condition?
YES : No action is necessary and testing is complete.
NO :  The wiring harness may be damaged or the connector 

may have loose, corroded or damaged terminals, or 
terminals pushed back in the connector. Repair the 
wiring harness as necessary. Verify that the central 
door locking system works normally.

STEP 5. Check ETACS-ECU connectors C-217 and front 
door lock actuator (LH) connector E-15 for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.
Q: Are ETACS-ECU connectors C-217 and front door lock 

actuator (LH) connector E-15 in good condition?
YES : Go to Step 6.
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 or replace the damaged component(s). Refer 
to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the central door locking system 

works normally.

STEP 6. Check the wiring harness between ETACS-ECU 
connector C-217 (terminal 22) and front door lock actuator 
(LH) connector E-15 (terminal 4).
