|---|---|---|---|
| 1 | CHECK FUSES Check that the following fuses are not blown. Is the fuse blown? | Replace the fuse after repairing the applicable circuit. | The fuse is normal. |
DIAGNOSIS PROCEDURE
DIAGNOSIS PROCEDURE Step Action YES NO 1 CHECK FRONT WIPER MOTOR FUSE Turn the ignition switch OFF. Check that the following fuse is not blown. Is the fuse blown? GO TO 2 GO TO 3 2 CHECK FRONT WIPER MOTOR (LO) SHORT CIRCUIT Disconnect IPDM E/R and front wiper motor. 2. Check continuity between IPDM E/R harness connector and ground. Does continuity exist? Repair or replace harness. Replace the fuse. (Replace IPDM E/R if the fuse is blown again.) 3 CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE SDT ACTIVE TEST Turn the ignition switch ON. 2. Select "FRONT WIPER" of IPDM E/R active test item. 3. While operating the test item, check voltage between IPDM E/R harness connector and ground. Is the measurement value normal? GO TO 4 Replace IPDM E/R. Refer to [ IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM): REMOVAL AND INSTALLATION ] 4 CHECK FRONT WIPER MOTOR (LO) OPEN CIRCUIT Turn the ignition switch OFF. 2. Disconnect IPDM E/R and front wiper motor. 3. Check continuity between IPDM E/R harness connector and front wiper motor harness connector. Does continuity exist? Replace front wiper motor.
