FRONT WIPER MOTOR LO CIRCUIT
Component Function Check
INFOID:0000000001629614
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-III ACTIVE TEST
1.
Select "FRONT WIPER" of IPDM E/R active test item.
2.
With operating the test item, check front wiper operation.
Is front wiper (LO) operation normally?
YES
>> Front wiper motor LO circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000001629615
1.
CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
1.
Turn the ignition switch OFF.
2.
Disconnect front wiper motor connector.
3.
Turn the ignition switch ON.
4.
Select "FRONT WIPER" of IPDM E/R active test item.
5.
With operating the test item, check voltage between IPDM E/R harness connector and ground.
Is the measurement value normal?
YES
>> GO TO 2.
NO
>> Replace IPDM E/R.
2.
