11.6.7.6 Wiper inoperation at intermittent

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. 2 of the wiper motor wire harness connector
CA14 and the effective body grounding point.

(a) Disconnect wiper motor harness

connector CA14.

(b) Place wiper switch to interval

(INT) position.

(c) Rotated ignition switch to "ON"

position.

(d) Use multimeter to measure

effective grounding voltage
between wire harness connector
CA14 terminal No. 2 and vehicle
body.

Standard voltage: 11-14 V

Confirm if the voltage conforms to
standard value.
