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 the switch is held in the 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 head lamps 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, 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 volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that switch is ON.

Operation Mode

Combination switch reading function has operation modes shown below.

Normal status

–

When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.

Sleep status

–

When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low cur-
rent consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 60 ms, and only input from light switch
system is accepted.

CAN Communication System Description

NKS001TS

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

CAUTION:

●

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

●
