NOTE:
Prior to the wiring harness inspection, check interme-
diate connector C-129 and junction block connector
C-210, and repair if necessary.
• Check the power supply line for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00

Step 5. Retest the system.
Check that the turn-signal lamps illuminate normally.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
Cope with Intermittent Malfunction
