Component Function Check

INFOID:0000000004202197

1.

CHECK FRONT WIPER LO OPERATION

IPDM E/R AUTO ACTIVE TEST

1. Start IPDM E/R auto active test. Refer to

PCS-14, "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 that front wiper LO operation and OFF.

Does the front wiper operate?

YES

>> Front wiper motor LO circuit is normal.
