NOTE:
Prior to the wiring harness inspection, check
intermediate connector G-21 and junction block
connector C-210, and repair if necessary.
• Check the output lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 25.
NO :
Repair the wiring harness.
Step 25. Retest the system.
Check that the turn-signal lamps.
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 :
Replace the rear turn-signal lamp assembly.

Inspection Procedure N-4: The turn-signal indicator lamp does not illuminate.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the turn-signal indicator lamp does not illuminate
normally, connector(s), wiring harness in the CAN
bus lines, the ETACS-ECU or the combination meter
may be defective.
POSSIBLE CAUSES
• The combination meter may be defective
• The ETACS-ECU may be defective
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Check that the hazard warning lamps
operate.
Check that the hazard warning lamps illuminate
normally.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
First, repair the headlamps. Refer to
Inspection Procedure N-2 "The hazard
warning lamps do not illuminate normally
Step 2. MUT-III CAN bus diagnostics.
Use the MUT-III to diagnose the CAN bus lines.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the CAN bus line (Refer to GROUP
54D, Diagnosis
Step 3. Check for combination meter diagnosis
code.
Check whether the combination meter-related
diagnosis code is set.
Q: Is the diagnosis code set?
YES :
Diagnose the combination meter (Refer to
GROUP 54A
− Troubleshooting
).
NO :
Go to Step 4.
Step 4. MUT-III actuator test
Perform the actuator test for the combination meter,
and check that the turn-signal indicator lamps
illuminate (Refer to GROUP 54A
− Combination
).
Q: Is the check result normal?
YES :
Replace the ETACS-ECU.
NO :
Replace the combination meter.
