Wiper Dial Position Setting
Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
Example: For wiper dial position 1
Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial posi-
tions 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper dial position 1.
Intermittent operation dial position 1: ON (Continuity exists between combination switch output 3 and input
1.)
Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input
1.)
Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input
2.)
BCM determines front wiper intermittent operation delay interval from wiper dial position and vehicle speed,
and sends wiper request signal (INT) to IPDM E/R.
CAN Communication System DescriptionNKS003WD
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex 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.
