Nissan Altima (L32) 2007-2012 Service Manual: Front wiper motor lo circuit
Component Function Check
1. CHECK FRONT WIPER LO OPERATION
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.
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.
NO >> Refer to WW-20, "Diagnosis Procedure".
Diagnosis Procedure
1. CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE
1. Turn the ignition switch OFF.
2. Disconnect front wiper motor.
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 normal? YES >> GO TO 2
NO >> Replace IPDM E/R. Refer to PCS-48, "Removal and Installation".
2. CHECK FRONT WIPER MOTOR (LO) OPEN CIRCUIT
