Front Wipers Operate For 10 Seconds, Stop For 20 Seconds, And After Repeating This Operation Five Times, They Become Inoperative

WARNING: This page is about a different car, the 2007 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

When auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front wipers, IPDM E/R considers front wipers locked and stops wiper output, which causes this symptom.
This status can be checked by using IPDM E/R "DATA MONITOR". Under this condition, "WIP PROT" reads "BLOCK".

CHECK IPDM E/R TO FRONT WIPER MOTOR
With CONSULT-II

Select "IPDM E/R" with CONSULT-II. With "DATA MONITOR", confirm that "WIP AUTO STOP" changes from "ACT P" to "STOP P" according to wiper operation.

Without CONSULT-II

GO TO 2.

OK or NG

OK: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION OF IPDM E/R ".

NG: GO TO 2.

IPDM E/R TO FRONT WIPER MOTOR AUTO STOP CIRCUIT INSPECTION

Turn ignition switch OFF.
Disconnect IPDM E/R connector and front wiper motor connector.

Check continuity between IPDM E/R harness connector terminal and front wiper motor harness connector terminal.

OK or NG

OK: Connect connectors. GO TO 3.

NG: Repair harness or connector.

IPDM E/R TO FRONT WIPER MOTOR AUTO STOP CIRCUIT VOLTAGE

Turn ignition switch ON.
Select "LO" on "ACTIVE TEST" screen.
While front wiper motor is stopped and while operating, measure voltage between IPDM E/R terminal 32 and ground.

IPDM E/R TO FRONT WIPER MOTOR AUTO STOP CIRCUIT VOLTAGE

IPDM E/R		(-)	Condition	Voltage (Approx.)
(+)
Connector	Terminal
E122	32	Ground	Wiper operating	Battery voltage
E122	32	Ground	Wiper stopped	0V

OK or NG

OK: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION OF IPDM E/R ".

NG: Replace front wiper motor. Refer to "WIPER MOTOR AND LINKAGE ".
