54B-377
DIAGNOSTIC PROCEDURE
Step 1. Check the power supply circuit.
When the ignition switch is turned to the LOCK
(OFF) position, check if the hazard warning lamps
illuminate.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Refer to inspection procedure A-2 "Check
the ETACS-ECU battery power supply
circuit
Step 2. Connector check: C-217 ETACS-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the defective connector.
Step 3. Measure the voltage at the C-217
ETACS-ECU connector.
(1) Remove the ETACS-ECU, and measure at the
junction block side.
(2) Turn the ignition switch to the ON position.
(3) Voltage between C-217 ETACS-ECU connector
terminal No.8 and body earth
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Go to Step 4.

Step 4. Check the wiring harness between C-217
ETACS-ECU connector terminal No.8 and the
ignition switch (IG1).
NOTE:
Prior to the wiring harness inspection, check junction
block connector C-203, and repair if necessary.
•
Check the power supply line to the ignition switch
(IG1) for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
−
How to
Cope with Intermittent Malfunction
NO :
Repair the wiring harness.
Step 5. Measure the voltage at the C-217
ETACS-ECU connector.
(1) Remove the ETACS-ECU, and measure at the
junction block side.
(2) Turn the ignition switch to the ACC position.
(3) Voltage between terminal 4 and body earth
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Go to Step 6.

Step 6. Check the wiring harness between C-217
ETACS-ECU connector terminal No.4 and the
ignition switch (ACC).
NOTE:
Prior to the wiring harness inspection, check junction
block connector C-202 <L.H. drive vehicles>, C-203
<R.H. drive vehicles> or intermediate connector
C-116 <L.H. drive vehicles>, and repair if necessary.
•
Check the power supply line to the ignition switch

Step 7. Retest the system.
Check that the interior lamp loaded signal is received
normally.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00

NO :
Replace the ETACS-ECU.
INSPECTION PROCEDURE N-18: The front passenger’s door lock key cylinder switch signal is not
detected. <L.H. drive vehicles>
CAUTION
Whenever the ECU is replaced, ensure that the
input signal circuit is normal.
COMMENTS ON TROUBLE SYMPTOM
Input signal from the front passenger's door lock key
cylinder switch is used to operate the central door
locking function. If the signal is abnormal, the central
door locking function will not work normally.
POSSIBLE CAUSES
•
Malfunction of the front passenger's door lock key
cylinder switch
•
Malfunction of the ETACS-ECU
•
Damaged harness wires and connectors
