Overhaul fuseIF30 circuit

A. Check whether fuse IF30 line is short circuited.

B. Repair the circuits. Confirm that there are no short circuits.

C. Replace the fuses with rated current.

Confirm whether the wiper works normally.

3

Inspect the voltage of the wiper motor wire harness connector terminal No. 1.

(a) Rotated ignition switch to "OFF"

position.

(b) Disconnect the wiper motor

harness connector CA14.

(c) Use multimeter to measure

effective grounding voltage
between wire harness connector
CA24 terminal No. 4 and vehicle
body.

Standard resistance: less than 1 Ω

(d) Turn ignition switch "ON"

position.

(e) Wiper switch was turned to "low"

gears position.

(f) Use multimeter to measure

effective grounding voltage
between wire harness connector
CA14 terminal No. 3 and vehicle
body.

Standard voltage: 11-14 V

Confirm whether the voltage and
resistance accord with the standard
value.
