Step 8. Check the wiring harness from B-134
ETACS-ECU connector terminal No.18 to C-11
luggage compartment lamp connector terminal
No.1
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector C-02 and junction block connector
B-113 repair if necessary.
• Check the input and output lines for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
).
NO :
Repair the wiring harness.

INSPECTION PROCEDURE M-4: The door-ajar warning lamp does not illuminate/extinguish normally.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the door-ajar warning lamp does not work normally,
the input signal circuit or the ETACS-ECU may be
defective.
POSSIBLE CAUSES
• Malfunction of the all door switches
• Malfunction of the combination meter
• Malfunction of the CAN bus line
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSIS 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 "When
the ignition switch is at the LOCK (OFF)
position, the functions do not work normally.
Check the battery power supply circuit to
the ETACS-ECU
."
Step 2. Pulse check
Check the input signals below which are related to
the door-ajar warning lamp.
OK: The M.U.T.-III sounds or the voltmeter
needle fluctuates.
Q: Is the check result normal?
All the signals are received normally. :
Go to Step
3.
The ignition switch (IG1) signal is not received. :
Refer to Inspection Procedure N-2 "The
ignition switch (IG1) signal is not received
."
All the door switch signals are not received. :
Refer to Inspection Procedure N-10 "All the
door switch signals are not received
."
Step 3. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Repair the CAN bus line (Refer to GROUP

Step 4. M.U.T.-III other system diagnosis code
Check whether the combination meter-related diag-
nosis code is set.
Q: Is the diagnosis code set?
YES :
Diagnose the combination meter (Refer to
GROUP 54A
− Troubleshooting
NO :
Go to Step 5.
Step 5. M.U.T.-III actuator test
Perform the actuator test for the combination meter,
and check that the door-ajar warning lamp illumi-
nates (Refer to GROUP 54A
− Combination Meter
Q: Is the check result normal?
YES :
Replace the ETACS-ECU.
NO :
Replace the combination meter.
