11.6.7.5 Wiper inoperation at low speed

Circuit diagram:

See 11.6.7.3 wiper does not work under any gear position.

Diagnostic steps:

1

Inspect the voltage of the terminal No. 3 of the wiper motor wire harness connector
CA14 and the effective body grounding point.

(a) Rotated ignition switch to "OFF"

position.

(b) Disconnect the wiper motor

harness connector CA14.

(c) Place wiper switch to high speed

gear (LOW) position.

(d) Turn ignition switch "ON"

position.

(e) Use multimeter to measure

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

Standard voltage: 11-14 V

Confirm if the voltage conforms to
standard value.
