d. Take a multimeter to measure the continuity of No. 30
and No.87terminals of the wiper high-low-speed relay.
Standard resistance:
Storage battery voltage Standard value

Battery positive pole connecting to
Terminal 85 and negative pole About 0Ω
connecting to Terminal 86

Check if the result is ok?
Yes>go to Step 3.
No> Repair or replace wiper high-low-speed relay.

3. Check ground circuit of wiper combination switch
a. Ignition switch:LOCK.

b. Disconnect the connector B030 of wiper combination switch.

c. Take a multimeter to measure the continuity between No.
8 terminal of wiper combination switch connector B030 and
grounding.
Standard resistance:

Multimeter connecting terminal Standard value

B030(8)-grounding About 0Ω

Check if the result is ok?
Yes>go to Step 4.
No> Repair or replace the ground circuit of wiper combination switch.

4. Check the wiper combination switch
a. Ignition switch:LOCK.

b. Disconnect the connector B030 of wiper combination switch.
c. Place the wiper combination switch at the high speed.

d. Take a multimeter to measure the continuity between
No.5 and No.8 terminals of wiper combination switch
connector B030.
Standard resistance:
