Check the fuse IF23 circuit .

(a) Check fuse IF23 circuit has short circuit phenomenon.

(b) Repair circuit to ensure that there is no short-circuit (note: when fuse is inserted, fuse will be

burned out. Inspect short-circuit between fuse to switch; when starting rear wiper switch or
rear washer switch, fuse will be burned out. Inspect short-circuit of grounding to wiper relay
or to rear washer pump.

(c) Replace with fuses with rated current.

Confirm whether the rear wiper works normally.

3

Inspect the effective grounding voltage of the terminal No. 10 of the wiper motor wire
harness connector IP52 and the body.

(a) Rotated ignition switch to "ON"

position

(b) Place rear wiper switch to ON

position.

(c) Use multimeter to measure

voltage between wiper switch
wire harness connector IP52
terminal No. 10 and vehicle body
effective grounding (note: do not
disconnect wire harness
connector IP52).

Standard voltage: 11-14 V

Confirm if the voltage conforms to
standard value.
