Inspection Procedure

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 "AUTO ACTIVE TEST ".
2. Confirm front wiper operation.

OK or NG

• OK: GO TO 4
• NG: GO TO 2.

OK or NG

• OK: Connect connectors. GO TO 3.
• NG: Check for open circuit in harness between front wiper motor and ground.

With CONSULT-II

1. Select "HI" on "ACTIVE TEST" screen.
2. When front wiper relay, and front wiper high relay are operating, check voltage between IPDM E/R terminals and ground.

Without CONSULT-II

1. Turn on front wipers using the auto active test. Refer to "AUTO ACTIVE TEST ".
2. When front wiper relay, and front wiper high relay are operating, check voltage between IPDM E/R terminals and ground.

OK or NG

• OK: Replace the front wiper motor. Refer to "REMOVAL AND INSTALLATION OF WIPER MOTOR AND LINKAGE  ".
• NG: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION OF IPDM E/R ".

Select "BCM" on CONSULT-II. With "WIPER" data monitor, check that "FR WIPER INT", "FR WIPER LOW" and "FR WIPER HI" turn ON-OFF according to operation of wiper switch.

OK or NG

• OK: GO TO 5.
• NG: Check wiper switch. Refer to "COMBINATION SWITCH READING FUNCTION  ".
