FRONT WIPER AND WASHER SYSTEM

BCM - Operation Table of Combination Switches
BCM reads operation status of combination switch using combinations shown in table below.
Sample Operation: (When Wiper Switch is Turned to LOW Position)

When wiper switch is turned to LOW position, FR WIPER LOW contact in combination switch turns ON. At
this time if OUTPUT 1 transistor is activated, BCM detects that voltage changes in INPUT 3.

When BCM detects that voltage changes in INPUT 3 while OUTPUT 1 transistor is ON, it judges that front
wiper switch is in LOW position. Then BCM sends front wiper request signal (LO) to IPDM E/R through
CAN communication.

If BCM detects that voltage changes in INPUT 3 when OUTPUT 1 transistor is activated again, it recog-
nizes that wiper switch is still in LOW position.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON,
electrical loads are activated with time delay. But this time delay is so short that it cannot be detected by
human senses.

Front Wiper Interval Time Is Not Controlled by Vehicle SpeedBKS001TX
1. CHECK COMBINATION METER FUNCTION
Check if speedometer operates normally.
Does the speedometer operate normally?
YES >> GO TO 2.
NO >> Refer to DI-20, "
Vehicle Speed Signal Inspection" .
2. CHECK “WIPER SPEED SETTING” STATUS IN WORK SUPPORT
1. Select “BCM” on CONSULT-II, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Select “WIPER SPEED SETTING” on “SELECT WORK ITEM” screen.
4. Touch “START” screen.
5. Check the current setting.
Is current setting
“ON”?
YES >> GO TO 3.
NO >> Change the setting. Refer to WW-19, "
