STEP 9. Check the wiring harness between C-206 
defogger relay connector No.1 and ignition 
switch (IG2).

NOTE: Prior to the wiring harness inspection, check 
junction block connector C-203, and repair if 
necessary.

•

Check the defogger power supply line 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 

P.00-6

).

NO : 

Repair the wiring harness.

STEP 10. Connector check: C-206 defogger relay 
connector and C-27 A/C-ECU connector
