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 :
