11.6.7.9 Rear washer inoperation

Circuit diagram:

Circuit diagram refers to 11.5.7.8 rear wiper does not work.

Diagnostic steps:

Notes:

Prior to the implementation of the diagnostic procedures, determine the rear wiper normally
operates.

1

Inspect whether the washing fluid reservoir level is sufficient.

(a) Inspect whether glass washing solution in liquid can is sufficient.

2 Add

glass

detergent.

A. Add

windscreen

detergent

into the fluid reservoir.

Confirm whether the rear washer works normally.

3

Inspect the voltage of the terminal No. 12 of the wire harness connector IP52 and the
effective body grounding.

(a) Rotated ignition switch to "ON"

position

(b) Washer switch after started

(c) Use multimeter to measure

effective grounding voltage
between wire harness connector
IP52 terminal No. 12 and vehicle
body.

(note: do not disconnect wire harness
connector IP52)

(d) Use multimeter to measure the

voltage of rear washer motor
terminal No. 2.

Standard voltage: 11-14 V

Confirm if the voltage conforms to
standard value.
