Component Function Check

INFOID:0000000005272690

1.

CHECK FRONT WIPER LO OPERATION

IPDM E/R AUTO ACTIVE TEST

1.

Start IPDM E/R auto active test. Refer to

PCS-13, "Diagnosis Description"

.

2.

Check that the front wiper operates at the LO operation.

CONSULT-III ACTIVE TEST

1.

Select "FRONT WIPER" of IPDM E/R active test item.

2.

While operating the test item, check front wiper operation.

Is front wiper (LO) operation normal?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to
