FRONT WIPER AND WASHER SYSTEM
Front Wiper Does Not Return to Stop Position (After Front Wiper for 10 Sec-
onds, They Stop for 20 seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
EKS00P57
CAUTION:
lWhen 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 are locked, and stops wiper output. That causes this
symptom.
lThis status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
ITEMS SHOWS “BLOCK”.
1.CHECK FRONT WIPER STOP SIGNAL
With CONSULT-ll
1. Select “BCM” on CONSULT-II. Select “WIPER” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P”
linked with wiper operation.
Without CONSULT-ll
GO TO 2.
Does the front wiper operate normally?
YES >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NO >> GO TO 2.
2.CHECK IPDM E/R
Check voltage between IPDM E/R harness connector and ground
while front wiper motor is stopped and while it is operating.
OK or NG
OK >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".

HEADLAMP WASHER OPERATION
With the headlamp washer switch in the ON position, the BCM receives input signal requesting. This input sig-
nal is communicated to the IPDM E/R via the CAN communication. The CPU located in the IPDM E/R controls
the headlamp washer relay coil, which when energized, power is supplied
