WIPER AND WASHER SYSTEM SYMPTOMS

■ CAUTION ■

Perform the self-diagnosis with CONSULT-III before performing the diagnosis by symptom. Perform the diagnosis by DTC if DTC is detected.

Symptom		Probable malfunction location	Inspection item
Front wiper does not operate.	HI only	Combination switch Harness between combination switch and BCM BCM	Combination switch Refer to Symptom Table.
		IPDM E/R Harness between IPDM E/R and front wiper motor Front wiper motor	Front wiper motor (HI) circuit Refer to Component Function Check.
		Front wiper request signal BCM IPDM E/R	IPDM E/R DATA MONITOR “FR WIP REQ”
	LO and INT	Combination switch Harness between combination switch and BCM BCM	Combination switch Refer to Symptom Table.

		Front wiper request signal BCM IPDM E/R	IPDM E/R DATA MONITOR “FR WIP REQ”
Front wiper does not operate normally.	Intermittent adjustment cannot be performed.	Combination switch Harness between combination switch and BCM BCM	Combination switch Refer to Symptom Table.
		BCM	—
	Intermittent control linked with vehicle speed cannot be performed.	Check the vehicle speed detection wiper setting. Refer to CONSULT-III Function (BCM - WIPER). NOTE： Factory setting of the front wiper intermitted operation is the operation without vehicle speed.
	Wiper is not linked to the washer operation.	Combination switch Harness between combination switch and BCM BCM	Combination switch Refer to Symptom Table.
		BCM	—
	Does not return to stop position [Repeatedly operates for 10 seconds and then stops for 20 seconds. After that, it stops the operation. (Fail-safe)]	IPDM E/R Harness between IPDM E/R and front wiper motor Front wiper motor	Front wiper auto stop signal circuit Refer to Component Function Check.
