Front Wiper Does Not OperateINFOID:0000000003533562
CAUTION:
During IPDM E/R fail-safe control, front wipers may not operate. Refer to PG-17, "
System Description"
to make sure that it is not in fail-safe status.
Inspection Procedure
1.CHECK IPDM E/R TO FRONT WIPERS
With CONSULT-II
1. Select "IPDM E/R" with CONSULT-II, and select "ACTIVE
TEST" on "SELECT DIAG MODE" screen.
2. Select "FRONT WIPER" on "SELECT TEST ITEM" screen.
Without CONSULT-II
1. Turn on front wipers using auto active test. Refer to PG-20,
"Auto Active Test".
2. Confirm front wiper operation.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2.IPDM E/R TO FRONT WIPERS CIRCUIT INSPECTION
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connectors and front wiper motor connector.
3. Check continuity between IPDM E/R harness connector termi-
nals and front wiper motor harness connector terminals.
4. Check continuity between IPDM E/R harness connector termi-
nals and ground.
