1. FRONT WIPE:
There are five wiping modes of Front wiper:
OFF
FLICK WIPE (
not controlled by BCM
)
INTERMITTENT (
controlled by BCM
)
LOW SPEED (
not controlled by BCM
)
HIGH SPEED (
not controlled by BCM
)
The wiper park position input switch is
used to detect when the wiper blade is at the
bottom of the wind screen.
OFF
In this state the front wipers should be in
the park position. (
Indicated by the wiper park
switch being active
) When the wiper mode is
changed from FLICK WIPE, INTERMITTENT,
LOW SPEED, or HIGH SPEED to OFF the wiper
continues the current wipe operation until the park
switch indicates the wiper is in the park position.
FLICK WIPE
When FLICK WIPE is selected, the wipers
move once across the windshield at low speed
and return to the park position. If FLICK WIPE is
permanently selected (
switch held on
), then the
wipers will move continuously across the
windshield at low speed. This mode is not
controlled by the BCM but will be detected as
LOW SPEED by the state change of the front
wiper parking switch input.
INTERMITTENT WIPE:
On vehicles with variable resistor Combi
switch installed the interval between consecutive
intermittent wipes shall be dependent on the
position of the interval wiper delay setting. There
are 5 settings for the variable resistor, of which
setting P1 shall be the shortest interval, and
setting P5 shall be the longest interval. If no delay
input is detected
(during open circuit error
condition)
or the variable resistor is not fitted, a
default setting of P2 will be used.
When the wipers are in INTERMITTENT
mode, if a shorter delay period is selected (
i.e
.
wiping to occur more often
), an “immediate wipe”
will be performed with wiping continuing at the
new, shorter interval selected. When a longer
interval is selected, the delay time for the new
interval is used to determine when the next wipe
is initiated. The delay time is measured from the
end of the last wipe, not from the time that the
interval was changed.
Delay Table:
LOW SPEED
When LOW SPEED is selected then the
wipers will move continuously across the
windshield at low speed. This mode is not
controlled by the BCM but will be detected by the
state change of the front wiper parking switch
input.
