MIST OPERATION
When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.
For additional information about wiper operation under this condition, refer to WW-5, "
LOW SPEED WIPER
OPERATION" .
If switch is held in mist position, low speed operation continues.
FAIL-SAFE FUNCTION
If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is
initiated until ignition switch is turned off. (If wipers were operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF)
COMBINATION SWITCH READING FUNCTION
Description

BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wip-
ers, according to the results.

BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1 - 5)
and five input terminals (INPUT 1 - 5).
Operation Description

BCM activates transistors of output terminals (OUTPUT 1 - 5) periodically, and allows current to flow in
turn.

If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1 - 5) and input terminals
(INPUT 1 - 5) becomes active.

At this time, transistors of output terminals (OUTPUT 1 - 5) are activated to allow current to flow. When
voltage of input terminals (INPUT 1 - 5) corresponding to that switch changes, interface in BCM detects
voltage change, and BCM determines that switch is ON.

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

When wiper switch is turned to LOW position, front 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 using 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.

CONSULT-III Function (BCM)NKS00529
CONSULT-III can display each diagnostic item using the diagnostic test mode shown following.
WORK SUPPORT
Display Item List
NOTE:
Regarding wiper speed setting, if the BCM set value is initialized by the use of CONSULT-III work support,
then set it individually to OFF after the initialization because it is automatically set to ON by initializing CON-
SULT-III.
