CHECK FRONT WIPER HI 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 HI 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 (HI) operation normally? YES >> Front wiper motor HI circuit is normal. NO >> Refer to . Diagnosis Procedure INFOID:0000000003761589 1. CHECK FRONT WIPER MOTOR (HI) 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. CHECK FRONT WIPER MOTOR (HI) 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 (HI) SHORT CIRCUIT Check continuity between IPDM E/R harness connector and ground. Hi : Front wiper (HI) operation Off : Stop the front wiper.
