WW-32 < DTC/CIRCUIT DIAGNOSIS > FRONT WIPER MOTOR HI CIRCUIT FRONT WIPER MOTOR HI CIRCUIT Component Function Check INFOID:0000000009719732 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:0000000009719733 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. 5. With operating the test item, check voltage between IPDM E/R harness connector and ground. *: According to front wiper protection function, IPDM E/R supplies voltage for 10 seconds (battery voltage) and 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 Hi : Front wiper (HI) operation Off : Stop the front wiper. Terminals Test item Voltage (Approx.)
