STEP 2. Measure the voltage at F-04 defogger 
connector. 

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Turn the defogger switch to the "ON" position.

(3) Measure the voltage between terminal 1 and 

body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

 Go to Step 14.

NO : 

 Go to Step 3.

STEP 3. Check the defogger relay continuity.

 Refer to 

P.55A-57

.

Q: Is the defogger relay in good condition?

YES : 

Go to Step 4.

NO : 

Replace the defogger relay.

STEP 4. Measure the voltage at C-206 defogger 
relay connector. 

(1) Remove the relay, and measure at the junction 

block side.

(2) Measure the voltage between terminal 5 and 

body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

 Go to Step 7.

NO : 

 Go to Step 5.

STEP 6. Check the wiring harness between C-206 
defogger relay connector terminal No.5 and the 
fusible link (1).

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connectors C-116 <LHD>, A-14 
<RHD>, C-122 <RHD> and junction block connector 
C-204, and repair if necessary.

•

Check the defogger relay power supply line for 
open or short circuit.

Q: Is the check result normal?
