STEP 6. Measure the resistance at the A-08X 
wiper deicer relay connector.

(1) Disconnect the connector, and measure at the 

relay box side.

(2) Resistance between A-08X wiper deicer relay 

connector terminal No.3 and body earth

OK: 2 

Ω

 or less

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : . 

Go to Step 7.

STEP 7. Check the wiring harness between A-08X 
wiper deicer relay connector terminal No.3 and 
body earth.

•

Check the earth wires 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 8. Measure the voltage at the A-08X wiper 
deicer relay connector.
(1) Turn the ignition switch to the ON position.

STEP 10. Check the wiring harness between 
A-08X wiper deicer relay connector terminal No.2 
and C-205 junction block connector terminal 
No.3.

•

Check the power supply line for open circuit.

NOTE:
