FRONT WIPER MOTOR LO CIRCUIT
Component Function Check
INFOID:0000000009945833
1.
CHECK FRONT WIPER LO OPERATION
IPDM E/R AUTO ACTIVE TEST
1.
Start IPDM E/R auto active test. Refer to
PCS-10, "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.
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:0000000009945834
1.
CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE
1.
Turn the ignition switch OFF, and wait for 20 seconds or more.
2.
Disconnect front wiper motor connector.
3.
Turn the ignition switch ON, and wait for 10 seconds.
4.
Check voltage between front wiper motor harness connector and ground.
*: According to front wiper protection function, IPDM E/R supplies voltage for 10 seconds (battery voltage) and
then stops for 20 seconds (0 V). This operation repeats 5 times, and then IPDM E/R stops voltage supply. To
perform the check again, turn ignition switch OFF, wait for 20 seconds or more, and then perform the check.
Is the measurement value normal?
YES
>> Replace front wiper motor.
NO
>> GO TO 2.
2.
CHECK FRONT WIPER MOTOR (LO) OPEN CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect IPDM E/R connector.
3.
Check continuity between IPDM E/R harness connector and front wiper motor harness connector.
Does continuity exist?
YES
>> GO TO 3.
NO
>> Repair the harness or connector.
3.
CHECK FRONT WIPER MOTOR (LO) SHORT CIRCUIT
Check continuity between IPDM E/R harness connector and ground.
Lo
: Front wiper (LO) operation
Off
: Stop the front wiper.

FRONT WIPER MOTOR HI CIRCUIT
Component Function Check
INFOID:0000000009945835
1.
CHECK FRONT WIPER HI OPERATION
IPDM E/R AUTO ACTIVE TEST
1.
Start IPDM E/R auto active test. Refer to
PCS-10, "Diagnosis Description"
2.
Check that the front wiper operates at the HI operation.
CONSULT 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 (HI) operation normally?
YES
>> Front wiper motor HI circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000009945836
1.
CHECK FRONT WIPER MOTOR (HI) OUTPUT VOLTAGE
CONSULT ACTIVE TEST
1.
Turn the ignition switch OFF, and wait for 20 seconds or more.
2.
Disconnect front wiper motor connector.
3.
Turn the ignition switch ON.
4.
Select “FRONT WIPER” of IPDM E/R active test item.
