Component Function Check

INFOID:0000000010048950

1.

 CHECK FRONT WIPER LO OPERATION

IPDM E/R AUTO ACTIVE TEST

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

PCS-11, "Diagnosis Description"

.

2. Check that the front wiper operates at the LO operation.

CONSULT ACTIVE TEST

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

2. While operating the test item, check front wiper LO operation and OFF.

Does the front wiper operate?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to 

WW-18, "Diagnosis Procedure"

.

Diagnosis Procedure
